[Mpi-forum] Agenda for MPI-Forum Day 2

[Martin Schulz via mpi-forum]

Hi all,

 

Thank you all who participated in the first day of the MPI forum meeting. We 
had a pretty productive day and already covered quite a bit of our agenda. We 
only have two remaining items, which will both be presented remotely from 
Europe. We, therefore, decided to skip the morning session here in Perth and 
resume after lunch at 1:30pm local time.

 

Please remember to vote (see email from Wes, you should have received a ballot 
email if you are eligible). The voting block still closes tomorrow at 9:30am 
local time. If one of the no-no votes would have failed, the matching full vote 
will be pulled from the second voting block. Otherwise, the modified issues/PRs 
will be on the ballot starting at 10am.

 

Thanks and see you tomorrow!

 

Martin

[Mpi-forum] IMPORTANT: make sure to register via Pawsey AND MPI-Forum for the MPI forum meeting next week

[Martin Schulz via mpi-forum]

Hi all,

 

Please keep in mind that you need to register twice for the MPI Forum next 
week, if you plan to attend. This is the case for both virtual and physical 
attendance. Otherwise, it is very had to track attendance and with that voting 
rights. As a consequence, your vote may not count.

 

You need to register via the Pawsey site (virtual attendance is free):

https://urldefense.us/v3/__https://events.csiro.au/Events/2024/May/22/IWOMP-EuroMPI-2024__;!!G_uCfscf7eWS!cQpDpgMGmosMdcI5_6zlCv89NZZLxVtEUs31cFeBxNGgMEBvii348je-iGeSy5qhclb1pL8IwJFBjaDAnBipaazw5vyQ$
 

 

You need to register via the MPI forum webpage (virtual or physical):

https://urldefense.us/v3/__https://forms.gle/RA9EPuLxVzFLdPFX7__;!!G_uCfscf7eWS!cQpDpgMGmosMdcI5_6zlCv89NZZLxVtEUs31cFeBxNGgMEBvii348je-iGeSy5qhclb1pL8IwJFBjaDAnBipaf1qIaHL$
 

 

At the moment we have still quite a few folks who are only registered via 
Pawsey website, and which are then not tracked by Wes’s spreadsheets. It would 
be great if you could fix this as soon as possible, so we have consistent lists 
again. 

 

Thanks,

 

Martin

[Mpi-forum] Dates/Location for September 2025 Forum and EuroMPI

[Martin Schulz via mpi-forum]

Hi all,

 

In discussions with the OpenMP community, we decided to hold EuroMPI 2025 again 
in conjunction with IWOMP, this time at UNC Charlotte, and with that also the 
MPI Forum. The dates will be:

 

Sep 29 Monday - Oct 1 Wednesday: EuroMPI
Oct 1 Wednesday - Oct 3 Friday: IWOMP + MPI Forum

 

If someone sees a major show stopper with these dates, please let me know (but 
please keep in mind, that the dates are already based on quite a lengthy 
discussion without much wiggle room anymore).

 

Thanks!

 

Martin

[Mpi-forum] MPI-Forum in 3 Weeks / Deadline for Announcements on September 9th

[Martin Schulz via mpi-forum]

Hi all,

 

Our next MPI Forum meeting is getting closer – we will meet September 23 and 24 
in Perth, Australia, right before EuroMPI, as well as online. If you are 
attending (either in person or virtually), please make sure you register. 
Instructions are here:

 

https://urldefense.us/v3/__https://www.mpi-forum.org/meetings/2024/09/logistics__;!!G_uCfscf7eWS!Zwm65vEcpj_w-0v8dY7OUuEShuXUcDiD6Gqz5bcJsxhE6bGVLWMRgbuRAhjCXe_EhPHTNo8uaYBTNA5YkJWq_R38aIJG$
 

 

This also means, the deadline for announcement (ballots, readings, errata, 
etc.) is NEXT WEEK on September 9th. Please send all items to the list by then 
and we’ll add them to the agenda. Also, if there are any working groups, who 
would like to meet in person, or if there are any other discussion items to be 
added, please let us know as well. 

 

Note, meetings times will be 9:00-17:00 local time in Perth – I realize this 
will cause some strange and uncomfortable meeting times both in the US and in 
Europe, but I hope you will stick with it nevertheless, as much as possible. 
Unfortunately, we do not have any other options here.

 

Thanks and hope to see you all soon (either in Perth or online),

 

Martin

Re: [Mpi-forum] Agenda for MPI Forum

[Martin Schulz via mpi-forum]

Hi all,

 

Based on the availability of speakers, I have uploaded a revised agenda:

 
The WG time on Monday is cancelled – to avoid confusion we will start the 
plenary still at 11am CT.
Tomorrow (Tuesday) will be dedicated to WG time – currently Tony has scheduled 
a slot for the collectives/partitioned, but other WGs are welcome to use the 
slot as well – WG chairs, please send out separate zoom links for your sessions
The rest is as indicated on the agenda – plenaries will be Monday and Thursday 
(with the ABI being scheduled for Thursday first thing)
 

Thanks!

 

Martin

[Mpi-forum] MPI Forum Next Week

[Martin Schulz via mpi-forum]

Hi all,

 

We have our next MPI Forum meeting scheduled for next week, at the usual times 
for virtual meetings from 9am to 1pm CT on Monday, Tuesday and Thursday (as 
Wednesday is a US holiday that we seemed to have missed when scheduling this).

 

My apologies, though, for not sending a reminder for this – I have to admit, 
this sneaked up on me a bit quicker than I thought and I did not see this in 
time to catch it at the 2 week mark. Unfortunately, no-one else happened to 
catch this either, which now leaves us with only ballot item, the change of 
rules we discussed last time. Wes and I thought about whether we could mitigate 
this with a “creative” use of no/no votes, but we both quickly came to the 
conclusion that would not be in the spirit of the forum and the rules and, 
hence, would like to refrain from this.

 

Nevertheless, we can and should still use this meeting to make progress on some 
the larger points, in particular the ABI text. With the timeline for (what we 
commonly expect to be) MPI 4.2 not set, this should actually not set us back in 
time.

 

Therefore, if you have any particular items, you would like to have on the 
agenda, please let Wes and me know, and we will add this to the agenda asap. 
Also, if there are WGs who would like to use larger blocks for dedicated 
discussion time, this would be a good opportunity as well.

 

Wes has already created a registration link, so please register asap if you 
plan to attend, so we can the needed data for eligibility and quorums.

 

https://urldefense.us/v3/__https://www.mpi-forum.org/meetings/2024/06/logistics__;!!G_uCfscf7eWS!ZtG5TuHfs6Iw087XbvCRBEMyWwUkXvBW3xig7J6D8aLe27j4hi85o7Ah143Hfqv9xPUt_YYQRAGP0dfGYKcY6PS_XRIa$
 

 

Thanks and my apologies again for the missing reminder – let’s still make the 
best out of it!

 

Martin

[Mpi-forum] Last Call for Readings, Ballots and WG Request for the March MPI Forum Meeting

[Martin Schulz via mpi-forum]

Hi all,

 

The two week deadline for the March MPI Forum meeting is this Monday (i.e., 
tomorrow). Please send any official reading and ballot requests to the list. 
Also, please let us know if there are any requests for plenary discussions or 
any WG requests; and please check that we got anything that you have already 
sent on our agenda.

 

Please note, one item on the agenda – right for the beginning – is the annual 
reconfirmation of WGs. We have neglected this a bit lately, but will follow 
through with it this time. Hence, if you are running an active WG or would like 
to support the continuation of an active WG, but can’t make it in the 
beginning, please let me know and we’ll take this into account.

 

The way it is shaping up right now, we’ll have WG time on Monday afternoon and 
will then start with plenaries on Tuesday morning, but this is still subject to 
change.

 

Thanks!

 

Martin

 

PS: If you haven’t registered, yet (virtual or in person), please do so as soon 
as possible.

[Mpi-forum] March Meeting / Agenda Requests and New Location

[Martin Schulz via mpi-forum]

Hi all,

 

Our March Meeting, which will be hybrid, is slowly coming up – we are scheduled 
for March 18-22 in Chicago. However, there has been a change in venue: the 
meeting will be hosted by Meta (thanks, Wes!). The new venue is still downtown 
Chicago, so hopefully this change will have no negative effect for anyone. 

 

The logistics page with exact location information is up and we will add a 
registration page soon (as soon we have exact cost estimates). 

 

In the meantime, please let me know if there are any additions to the plenary 
sessions and – for now more important – if any WG would like to use the meeting 
for dedicated WG time. For now, I have reserved the two sessions for WG time 
(one on Monday and one on Tuesday), but we can adjust as needed.

 

Thanks!


Martin

[Mpi-forum] Working Group Time at the March Forum Meeting?

[Martin Schulz via mpi-forum]

Hi all,

 

Happy New Year everyone!

 

Our next forum meeting (in hybrid form) is coming up March 18-22 in Chicago. 
While there is certainly some time for the plenary agenda items, it would be 
good to schedule time for working groups as soon as possible. Are there any 
working groups who would like to use the opportunity to meet in person/hybrid?

 

Please let me know and I can add that to the agenda.

 

Thanks!

 

Martin

[Mpi-forum] MPI Forum Dates for 2024

[Martin Schulz via mpi-forum]

Hi all,

 

Thank you all for an, again, quite productive and efficient MPI Forum meeting!

 

As discussed at the end of the meeting, we need to fix our meeting dates for 
the next year. Here are the current suggestions:

 
March 18-22, AWS Chicago (and online)
Please discuss the use of WG time in the WGs first and get back to Wes and 
myself if you would like to request WG time in Chicago
June 17-20 (tentative)
Online only
September 23-25, Perth, Australia
Before EuroMPI, which is scheduled for September 25-27
Also together with OpenMP events
December 9-12
Online only (tentative)
 

The dates in March and September are fixed, but for the online dates in June 
and December we do have some flexibility still. If you see any major conflicts 
on those weeks, please let us know.

 

Thanks!

 

Martin

When will our MPI Forum meeting start today and the rest of the week?
The Agenda on the website states we should be working since 0 am US Central

I assume 9 am US central (4 pm CET), lasting for 4 hours per day as usual?

[Mpi-forum] MPI 4.1 Published

[Martin Schulz via mpi-forum]

Dear MPI Forum Community,

 

For all of you who could not join us yesterday, I am happy and excited to 
announce that we finalized and then ratified the MPI 4.1 Standard yesterday! 
The document is already online at:

 

https://www.mpi-forum.org/docs/mpi-4.1/mpi41-report.pdf

 

Many thanks to all of you for contributing to MPI 4.1 and making it possible to 
get this version out before SC23. Special thanks to Wes and Bill who wrangled 
with git and Latex issues until the very end. 

 

I know this was a lot of work, both regarding new functionality and all the 
clean-up items (which may not look like that much on paper, but I think will 
really help the readability and sustainability of the standard), as well as the 
tough final push! This is really a significant accomplishment and it wouldn’t 
have been possible without the dedication, time and expertise from this group!

 

If you are at SC23, please join us for the MPI Forum BoF (Tuesday 12:15-13:15 
local Denver time) where we will present MPI 4.1 to the HPC community. If we 
get critical mass, we could also attempt a group photo at this time!

 

Also, please help publicize the new standard through your various channels! If 
there are any particular ideas that we could do as a whole forum, please let us 
know as well!

 

Thanks again and I am looking forward to continuing to work with all of you 
towards our next milestones MPI 4.2 and MPI 5.0!

 

Martin

 

 

PS: As we finished our agenda items for this meeting yesterday, the fourth and 
last day of the voting meeting is cancelled. Enjoy the weekend!

Subject: MPI Forum Virtual Meeting Wednesday on MPI_Psend_init_c & 
MPI_Precv_init_c

 

Hi all,

 

We are getting close to the final version of MPI 4.1, but there is still the 
ongoing discussion on what to do with the mistake/decision that we took on the 
count parameters in MPI_Psend_init_c & MPI_Precv_init_c. For those who have not 
been following this, here is the link to the github thread:

 

https://github.com/mpi-forum/mpi-issues/issues/765

 

We need to settle this one way or the other, but a growing email thread does 
not seem to be the most effective way. Wesley and I are therefore suggesting to 
use our traditional meeting slot on Wednesday to hold a virtual meeting on this 
(Wednesday Oct. 11th, 10am US CT). Call-in information will be, as usual, on 
the forum website.

 

I hope this works for most of you and hopefully we’ll find an easy way to 
resolve this.

 

Thanks!

 

Martin (and Wesley)

[Mpi-forum] Complete RC open issues list from MPI Forum RCM

[Martin Schulz via mpi-forum]

Hi all,

 

First of all, thank all for a very productive and focused meeting last week on 
our path to MPI 4.1 – both to those attending in person in Bristol and to those 
online at often quite unfortunate hours!

 

As discussed, I compiled a list of all open points and consolidated this into a 
single spreadsheet, which is here:

 

https://docs.google.com/spreadsheets/d/1ZpsyVTnfNHv85K9Mzi_3niNXdmQ67yV2iwSaoYBTGpI/edit?usp=sharing

 

There is a total of 380 points that we collected that we think should be still 
addressed somehow. I placed them into five categories:

 
MPI 4.1: This is more or less the default category and should at the end 
contain all small changes that we still want to apply the standard (and which 
will be voted on). For all items in these categories, we will need Pull 
requests and Issue created.
Editor changes: Small changes and formatting changes that Bill will apply 
directly – no separate PR or Issue is necessary. Once an item is in this 
category, please do not touch it (unless Bill pushes it back to one of the 
other categories)
Flow: Items covering bad page breaks, strange spacing, etc., which do not 
change the contents of the document and which need to be addressed at the very 
end during layout – Bill will go over them at the end and these items are 
mainly meant as hints for him to pay attention to
MPI 4.2: Items we think are too big and which should be pushed to the next 
version of the standard or separate erratas. For those, we will eventually also 
need PRs and Issues and we could technically start reading them in the next 
meeting if there is time.
Reject: items we decided to drop
 

Note: this list all points individually as we recorded them – multiple of them 
can of course (and should) be grouped into a single PR or Issue.

 

ACTION ITEMS:
If you reviewed parts of the standard, please check the list and make sure 
comments are properly recorded (if you noticed mistakes in the page numbers, 
please let me know, as this means updates in hidden parts of the spreadsheet)
CC chairs: please take a look at all comments for your chapter and ensure that 
they are consolidated correctly. By default you are responsible for completing 
or shepherding all items in your chapter.
If you have created PRs and Issues (or if you do so from now on), please place 
them into the appropriate columns, so we can track it and place yourself into 
the owner category.
If the PR/Issue is complete and ready for review, please mark this in the 
column “DONE”.
If you think an MPI 4.1 issue should be moved to one of the other categories, 
please move the checkmark and note the reason for the decision in the 
“Comments” column at the end (together with your name).
 

As Wes noted on Friday, we have a short time line here – all items we want for 
4.1 must be in the DONE column by September 26.

 

I hope this all makes sense and covers all steps forward – if you have any 
questions, comments or concerns, please let me know.

 

Thanks!


Martin

 

PS: This is a shared spreadsheet, so please be careful when editing and please 
do not change anything structural. Also, mark any decisions, observations or 
comments in the last column together with your name, so we have a track record 
for the discussions next time. Thanks!

[Mpi-forum] MPI Forum Starting Tomorrow / Wednesday: Missing Reviews / Chapter Readings

[Martin Schulz via mpi-forum]

Hi all,

 

We will be starting tomorrow afternoon (local time) with our MPI Forum RC 
Meeting. The core will be the reading of the changes made to all chapters, as 
well as the creation of a list of all outstanding issues.

 

For this, we are still missing a few reviews of the MPI standard – the 
procedure is laid out below in a previous email by Wesley. If you haven’t had 
the chance to do this, yet, please complete your section as soon as possible, 
so that we can get a complete overview. If you would like to volunteer for an 
open section, please let us know as well.

 

Also, just a reminder for all chapter committee chairs: please let us know if 
you won’t be reading your chapter diffs who from your committee you have 
designated to do so.

 

Thanks and see you tomorrow (in Bristol or online),


Martin

Subject: Re: Action Required -- MPI 4.1 RC Review

 

Hi folks, 

 

I’m sorry that I left out the detail about the page numbers. A couple of you 
have already asked about this.

 

The document essentially has two sets of page numbers. The first is the one 
that your PDF reader will likely give and starts at 1. The second is what is 
printed in the document and starts at i (lowercase “eye”).

 

The original numbers in the sheet were the first set, but I’ve now added 
another set of columns with the second as well. So you can hopefully decipher 
which ones are assigned to you from that.

 

When you fill out the form with your response, please use the first set of 
numbers.

 

Thanks,

Wes

Hi all,

 

Thanks to each of you for being an active participant in the MPI Forum this 
year. As we come to the end of the MPI 4.1 ratification process, we have one 
more ask for each of you who have been most involved.

 

As we discussed during the July 2023 meeting now is the time that we will 
collectively review the MPI 4.1 RC Document before we go through the final 
steps for ratification. Each of you who have been active participants over the 
last year have been assigned a chunk of the document (each chunk is 30 pages). 
Your assignments can be found on this Google Sheet:

 

https://docs.google.com/spreadsheets/d/16o1Zf0YGGEIHIn9ULp9IodBok2TF2YNKEFHJ3f-6YGE/edit?usp=sharing

 

You can find the document itself here:

 

https://github.com/mpi-forum/mpi-forum.github.io/raw/master/docs/mpi-4.1/mpi-41-rc1.pdf

 

As you are reviewing, these are the guidelines for things you should be looking 
for:

 

1. Formatting and whitespace problems

2. Spelling errors or other typos

3. Logical inconsistencies in the overall document

4. Problems with the way approved changes were applied

 

You are welcome to note any other issues you see as well.

 

As you finish your review, please use this form 
(https://forms.gle/93hXANvVkp3MhrCD9) to provide your feedback. I’ll be able to 
triage issues from there. If you have no notes, please still fill out that form 
and mention that so we know each chunk has been covered. These reviews must be 
completed by September 8th (there are no review deadline extensions 😀) so we 
can discuss them at the meeting the following week. If you cannot complete your 
assignment by then, please let Martin and I know as soon as possible so we can 
try to find someone else who is willing to take over your section. If you are 
willing to look through an extra section, please let us know that too so we can 
line up extra reviewers just in case.

 

If you have any questions, feel free to reach out to us for clarification.

 

Thanks,

Wes

[Mpi-forum] We need new dates for the March 2024 meeting

[Martin Schulz via mpi-forum]

Hi all,

 

We are planning to hold the March 2024 meeting in the Chicago area – U of I 
graciously has offered space in the Big Ten Center close to O’Hare airport.

 

Unfortunately, the dates we originally had in mind will not work. Here are the 
alternate dates currently held for us:

 
Option 1: reduce to 2 days (Feb 27/28) only 
Option 2: March 4-8 , note this conflicts with SIAM-PP in Baltimore
Option 3: March 18-22 (a bit later than usual)
 

Are there any particular preferences or major conflicts? How big is the 
conflict with SIAM?

 

Please let me know in the next few days.

 

Thanks,

 

Martin

[Mpi-forum] MPI Forum VOTING BLOCK open until 1pm US CT

[Martin Schulz via mpi-forum]

Hi all,

 

Just as a reminder – we will not meet anymore today or tomorrow for the MPI 
forum meeting, as we (almost) concluded yesterday. However, one item is still 
open – if you haven’t done so, please remember to vote for the remaining 
outstanding errata votes. If you are eligible you should have gotten an email 
with the voting link yesterday. The voting block will stay open until 1pm US 
CT, i.e., for about the next 4 hours.

 

Thanks!

Hi Rolf, 

No problem - I added a meeting slot for next week.

@All: as for this week, let's meet anyway and go over the pending items - this 
may be a short meeting, though, as not much seems to be left at this point - 
thanks to Wesley, here is the current overview:

Therefore, I must skip my topics #710/PR823 and #676/PR825 to next week.
I hope that any discussions can already be resolved during this weeek.
If you are interested, please look at the commented pdf files.

[Mpi-forum] Upcoming MPI Meetings

[Martin Schulz via mpi-forum]

Hi all,

 

Just has a heads-up, as our next voting meeting is coming up quickly (due to 
our compacted schedule for MPI 4.1) – we will meet virtually July 10-13, in the 
usual timeslots from 9am-1pm US CT. The agenda is being already formed at (feel 
free to send items rather earlier than later):

 

https://www.mpi-forum.org/meetings/2023/07/agenda

 

Note, the deadline for announcing ballots is: June 26th (2 weeks prior). Please 
note, that this will be the last chance (assuming we stick to our schedule) to 
announce any 2nd votes or erratas to make it into MPI 4.1. The following voting 
meeting will already be during EuroMPI in Bristol and we are planning to make 
this the release candidate meeting with the complete review of the standard.

 

In order to prepare for this meeting, we still have the chance to have several 
virtual meetings in order clarify text before the June 26 deadline. Currently, 
we only have one slot scheduled:

 

June 7th: discussion of pending erratas (Rolf)

#705 Errata: Fortran has only compile-time constantsRolf,Joseph

#710 Errata: 'Pending communication' not defined in MPI_Comm_disconnect
Rolf

#676 Errata: 'Pending operation' not defined, pending proper definition
Rolf,Joseph

 

If there are any further requests for virtual meetings, please let me of Wesley 
know. Unless there a specific requests or other changes in schedule, I am 
planning to use the June 14th slot to discuss any pending items on the github 
project boards to make sure we don’t miss anything before the deadline.

 

Thanks!

 

Martin

[Mpi-forum] Next Voting Meeting starts May 2nd - Deadline for announcements is April 18th

[Martin Schulz via mpi-forum]

Hi all,

 

We’ll have our next voting meeting starting May 2nd – this will be a virtual 
meeting and we’ll use the usual timeslots from 9am to 1pm US Central time. A 
preliminary agenda is already online (I know a few items are still missing, 
they will be added soon). The deadline for any ballot or reading announcements 
is Tuesday April 18th. Priority will be to complete the needed discussions, 
(no/no and errata) readings for MPI 4.1 and the associated votes, but there 
should be time for other items. Hence, if any WG would like to have plenary 
discussions, please let me know.

 

Thanks,

 

Martin

Thanks for digging this out – yes, that was the list. If the respective groups 
are still active and would like to participate, please send me a contact. Also, 
there are a few new additional MPI libraries from the last few years (or even 
older) – if you would like to be included let me know as well.

The last version of this slide that I could find easily was from 2018 
(https://www.mpi-forum.org/bofs/2018-11-sc/intro.pdf slide 3). At that time, we 
had these implementations:

MVAPICH 
Open MPI
Cray
Tianhe
Intel MPI
IBM (BG/Q, PE, Spectrum)
HPE
Fujitsu
Microsoft
MPC
NEC
Sunway
RIKEN
Adaptive MPI
 

I’m sure there are some on here that would drop off, but maybe we can start 
with these folks?

Hi all,

 

We have gotten a few requests to restart the tradition on reporting on the 
status of MPI implementations at the traditional SC and ISC BoFs, in particular 
their compliance with the newest standard on the various new features. I would, 
therefore, like to try to get that information together for ISC, but I will 
need from the MPI implementors. 

 

For the main open source implementations I can guess the right contacts, but 
then we have a wide range of other implementations and variants, which would be 
great to include as well. Therefore, I would like to ask any MPI implementation

[Mpi-forum] Reading Announcements Buffer Send Handling

[Martin Schulz via mpi-forum]

Hi all,

 

Adding to Rolf’s previous announcement of the reading of Issue 586 
(MPI_Buffer_attach and Sessions):

 
The issue/PR has been updated to reflect the discussion from last time
Zero buffer size behavior is now the same as in MPI 4.0
Automatic buffering is enabled by using a constant for the buffer argument
Small text updates
No changes in default behavior
 

Further, there are now two companion issues with PRs, which I would like to 
read as well:

 

Issue 684: make the automatic buffering the default behavior

Issue 685: adds iflush procedures

 

Note: the PRs for those two issue contain all changes for 586 as well and will 
have to properly merged should they pass. Also, should 586 fail, these issues 
will be retracted.

 

Thanks!

 

Martin

[Mpi-forum] MPI Forum Virtual Meeting today (Wednesday) 10am US CT

[Martin Schulz via mpi-forum]

Hi all,

 

Just as a quick reminder: as discussed last week, we’ll use the next two MPI 
Forum Virtual Meetings (today/Wednesday 10am US CT and next week, same time) to 
cover the three remaining topics that require pre-discussions before the voting 
meeting in March. Those are:

 

- MPI_(MIN|MAX)LOC (covered by Marc-Andre)

- Buffer attach (Martin/Rolf)

- Memory Alloc Kind Info (Jim)

 

The exact timing and order may change based on how the discussions go and based 
on availability.

 

Dial-in coordinates are, as usual, on the MPI Forum website.

 

Thanks!

 

Martin

[Mpi-forum] Upcoming Meeting Schedule for the MPI Forum

[Martin Schulz via mpi-forum]

Hi all,

 

We need to discuss the schedule for the upcoming meetings in 2023/24. Formally, 
we will decide on this during the MPI forum meeting, but I wanted to send out 
the following proposal ahead of time, so everyone can check for major conflicts 
and or other issues. Note, we decided to hold the spring meeting in 
person/hybrid (preferably ET/CT), summer and winter fully virtual and Fall 
together with EuroMPI (and keep co-locating EuroMPI and IWOMP).

 

For the spring meeting, we have an offer to host this in Boston – location and 
dates are confirmed:

 

Spring Meeting:

    March 13 to 16, 2023, Boston (AWS Offices, thanks Quincey)

    Start noon, end noon

 

Assuming we finish all final reading in that spring meeting, and we want to hit 
SC for MPI 4.1, we need two voting meetings instead of one summer meeting (both 
virtual):

 

Suggestions (decent spacing plus avoiding summer conflicts, I hope):

    May 1 to 4, 2023, virtual

    Could be fewer days if votes are the core items

 

    July 10 to 13, 2023, virtual

    Could be fewer days if votes are the core items

 

The fall meeting will be with EuroMPI in Bristol – this will be the RCS meeting 
(the one we read the entire standard page by page – hence, onsite will make 
things a lot easier):

 

Fall Meeting:

    September 13-15, 2023, Bristol (right after EuroMPI, parallel 
to IWOMP)

    Three full days

 

Again, assuming we intend to hit SC23 for MPI 4.1, we need an additional voting 
meeting.

 

Suggestion: two weeks before SC23

    October 31 to November 3, 2023, virtual

    Could be fewer days depending on agenda

 

Starting after SC23 we would be back on a normal schedule:

 

Winter Meeting:

    December 4-7, 2023, virtual

    

Spring Meeting (space reserved):

    February 26-March 1, 2024, Chicago (Big Ten Center in Chicago, 
thanks to Maria and Bill)

    Start noon, end Noon

 

Summer Meeting:

    June timeframe, virtual

    Let’s wait for 2024 summer conflicts before fixing dates

 

Fall Meeting:

    September, again with EuroMPI and IWOMP 

    Location would be Pawsey Supercomputing Center near Perth, 
Australia

    (the location was already picked by IWOMP - I know this is a 
stretch for many, but we will have a hybrid option and it would help cover an 
area that is traditionally underrepresented in the forum and – especially – the 
conference)

 

Please take a look at the dates and send me any information about major 
conflicts.

 

Thanks!

 

Martin

Re: [Mpi-forum] December Meeting Draft Agenda Posted

[Martin Schulz via mpi-forum]

Hi Jeff,

 

This just means changes were made since the reading on the respective issues. 
If the No No passes, then we proceed to the first vote. If it fails, we either 
vote on the issue/PR without these changes or (more likely) restart the reading 
process, as the changes are deemed too large for the No No process.

 

Hope this helps,

 

Martin

Why are 407, 429, 551 and 553 listed under both "NO NO" and "FIRST"?  Is this 
because if they fail the "NO NO" vote then they proceed down the 2 vote path?

[Mpi-forum] Key Points from the MPI Forum, September 2022

[Martin Schulz via mpi-forum]

Hi all,

 

Thanks to all of you who participated in the September MPI Forum – either in 
person or remotely. I hope the hybrid mode worked out for everyone.

 

A few key points from the meeting as a summary for those who were there (please 
feel free to amend if necessary) or as update for those who couldn’t be there:

 
We completed an assessment of all open and possibly gating issues for MPI 4.1 
from all WGs – the slides covering the details are available from the meeting 
page
Based on that (as most critical issues are close), we decided on a rough 
timeline to ratify MPI 4.1
Last readings in March 2023
Additional voting meeting April/May 2023 (virtual)
Second votes during the June 2023 meeting (virtual)
First ratification meeting September 2023 (with EuroMPI, see below)
Additional virtual ratification meeting (virtual) in October 2023
MPI 4.1 ready for SC 23
To make this work, we need the WGs to complete the items on the slides by March 
2023. The same is true for all tickets assigned on the MPI 4.1 github project 
board, which in many cases refers to chapter committees. 
The board is at: https://github.com/orgs/mpi-forum/projects/1
We need to make sure chapter committees are active and have engaged members – 
we will go over this in December and replace members as needed – chapter 
chairs, please look at your committees and let us know if changes are needed.
The discussion so far shows that virtual or hybrid meetings are here to stay – 
we are working on an update of the rules document to codify this, which will be 
discussed on 10/19 in the virtual meeting
Nevertheless, we got good feedback that a) the hybrid part worked and b) that 
the folks in person found the personal interactions very valuable. We are 
therefore strongly considering holding the March meeting in person again with a 
hybrid component – I hope a lot of you would consider joining in person. To 
make the hybrid component palatable for the most folks, we are looking at 
locations in the eastern US time zone.
EuroMPI 2023 and the 2023 September forum will be Bristol, UK – again 
co-located with Iwomp and with a virtual component and on the same schedule, 
which worked very well this year
To keep the connection to Iwomp, EuroMPI and the forum in September 2024 will 
likely be in Perth, Australia (hosted by the Pawsey supercomputing center) – 
details to be done, but we strive again to offer a virtual component
 

This should cover the majority of larger (non-technical) topics covered – 
please let us know if there are any comments, corrections, approvals or 
concerns!

 

Thanks!

 

Martin

[Mpi-forum] MPI Forum Agenda Posted

[Martin Schulz via mpi-forum]

Hi all,

 

We have posted the preliminary final agenda for the forum meeting on the usual 
space at:

 

https://www.mpi-forum.org/meetings/2022/09/agenda

 

Note, in contrast to our purely virtual meetings, all times are noted in 
Eastern Time, i.e., local time of the meeting. Also, we will have to utilize 
the whole days (8:30-17:00 local time). I realize this is not ideal for many 
virtual participants, but for a hybrid meeting I fear this is the best we can 
do.

 

We also had two requests for WG meetings – to not limit the plenary time (where 
we have a full agenda), we decided to overlap them with the tutorials, which I 
hope works for everyone. Of course, feel free to also arrange other times 
outside the normal program, but please not that Tony informed us that the 
meeting facility is only available from 8:00 to 17:00.

 

As you have seen in the previous emails, the registration for in-person is 
closed, but registration for virtual attendance is still open (we noticed that 
a few usual suspects are still missing, please register asap if you plan to 
participate to make Wesley’s bookkeeping job easier). Note, there is a fee this 
time, even for virtual attendance (as it always has been before the pandemic) 
to cover a share of room and virtual logistics costs.

 

Thanks and hope to see all of you (virtual or in person) next week,

 

Martin

[Mpi-forum] No MPI Virtual Meeting today / Reminder: please send agenda requests

[Martin Schulz via mpi-forum]

Hi all,

 

We do not have any scheduled topics for this week and hence the MPI virtual 
meeting today is cancelled.

 

As a reminder: next Wednesday is the two week deadline for the MPI forum in 
Chattanooga – please send reading and ballot requests by then to the MPI Forum 
email list. Also, if there are any other requests for the agenda (general 
discussions or WG meeting times), please also send those as soon as possible.

 

Thanks!

 

Martin

 

PS: If you plan on attending EuroMPI, please don’t forget to register – if you 
do not plan to attend, perhaps rethink your decision ;).

[Mpi-forum] Virtual MPI-Forum Meeting Today at 10am Central Time

[Martin Schulz via mpi-forum]

Hi all,

 

Just as a quick short term reminder – we will have a virtual MPI forum meeting 
today at 10am US Central Time – the link is, as usual, linked via the MPI forum 
website.

 

https://www.mpi-forum.org/virtual_meetings/

[Mpi-forum] Virtual MPI Forum Meeting Tomorrow (ACTION ITEMS INCLUDED)

[Martin Schulz via mpi-forum]

Hi all,

 

After some break, we’ll have an MPI Forum Virtual Meeting tomorrow at the usual 
time – 10am CT – and using the usual link, which is on github at the usual 
place.

 

As mentioned before, the goal tomorrow is get an overview of the state in the 
various working groups and chapter committees in our progress to MPI 4.1. We 
will use this to build a todo/gating issues list during the September meeting 
and with that plan a (hopefully) concrete timeline for MPI 4.1.

 

However, this means that we need your input on two things:
The status of the open items on the github boards (see Wesley’s email from July 
6th)
Any open issues from the WGs that should be considered for MPI 4.1 (or which 
ones can be postponed to MPI 5.0)
(keep in mind, though, MPI 4.1 was not supposed to include major items or 
additions, just cleanup and minor urgent changes)
 

Therefore, I would like to ask all of to review these items above (especially 
if you are tagged on one of the items on the github boards). Also, it would be 
really helpful, if each WG lead would be able to join us tomorrow or have a 
representative, so we can discuss the open issues.

 

For reference, here are the links to the boards:

 

* https://github.com/mpi-forum/mpi-issues/projects/3 (GitHub’s old project 
boards version)

* https://github.com/orgs/mpi-forum/projects/1/views/2 (GitHub’s new project 
boards version)

 

Thanks and hopefully see/hear you all tomorrow,

 

Martin

[Mpi-forum] FEEDBACK REQUESTED: Upcoming MPI Forum Meetings

[Martin Schulz via mpi-forum]

Hi all,

 

At the end of the forum meeting we also had an initial discussion on how to 
proceed with the MPI Forum meeting series, now that the pandemic is at least 
(hopefully) nearing its end.

 

First, the next meeting will be 9/28-9/30 and it will be held as a hybrid 
meeting, i.e., both online and in person after EuroMPI in Chattanooga – 
following our rules, this will again be an “exceptional virtual voting 
meeting”, i.e., the same rules will apply as for the fully virtual meeting this 
week. What will change, though, is that we will follow a timing for the 
sessions that matches the local setup. However, we do know that this will 
create issues for folks joining from other timezones and we will take this into 
account.

 

As for the following meetings: there seemed to be a consensus that our normal 
cadence of 4 voting meetings per year is still appropriate (please speak up if 
you disagree). Following our usual timeline, the following dates/weeks could 
work:

 

Winter 2022: December 5-8, 2022

Spring 2023: February 27-March 2, 2023

Summer 2023: May 29-June 1, 2023

Fall 2023: together with EuroMPI in September (Dates tbd.)

 

Note, this are just proposals! Please check if there are any substantial 
conflicts – we will adjust the dates if there are such and we will send a final 
proposal for dates before deciding on final dates. However, please send 
possible conflicts rather sooner than later, to give us time to react.

 

Third, we had a discussion on whether to return to all or part in Person 
meetings – both for the tail end of the pandemic, but also afterwards. The 
general consensus from the attendees this week was that we need some in person 
meetings again (1-2 per year), but neither fully virtual nor fully only in 
person are good options. Also, there was a strong push towards allowing hybrid 
participation of some sort, possibly coupled with different voting roles. 
However, it was also clear that hybrid meetings will cause technical challenges.

 

As a consequence, we decided to wait out the first hybrid meeting in September 
and then decide on how to proceed after that. The December meeting will be 
virtual for sure, with a possible hybrid option for the Spring meeting. If we 
do want to go hybrid for the spring, though, we would need volunteers that 
could host us in their organization and that have good video conference setups 
(similar to what we had at Cisco or Microsoft) in order to support such a 
meeting. If you are interested and willing to host the MPI forum (for the 
spring meeting or also in general), please let Wesley and me know.

 

I think this covers the discussion at the forum meeting – if I missed 
something, or if you were not able to attend the discussion this week and would 
like to comment, please follow up here.

 

Thanks!


Martin

[Mpi-forum] ACTION ITEM: timeline for MPI 4.1

[Martin Schulz via mpi-forum]

Hi all,

 

As mentioned during the forum meeting, we should start thinking about the 
timeline for MPI 4.1. Our goal was to produce a relatively quick turn-around 
version of the standard, with a big focus on clean-up and fixed terminology and 
only minor technical additions. While we have made good progress in this 
direction, several important items are still outstanding. I would like to use 
the September meeting to make a final collection of these items and with that 
start fixing a timeline that we can plan with (keep in mind, we need several 
voting meetings before the last idea being read and when a standard can be 
ratified).

 

To enable this, it would be helpful if each working group and chapter committee 
could provide a list of items they still consider outstanding and needed for 
MPI 4.1. Also I would like everyone to take a look at the MPI 4.1 project board 
at 

 

https://github.com/mpi-forum/mpi-issues/projects/3

 

and check whether you have items there and whether they are still in the MPI 
4.1 range.

 

I would like to get a preliminary assessment on this by mid July, so we can 
have a first discussion at the July 20th virtual meeting. I hope this gives 
enough time – please let me know if you have questions or concerns!

 

Thanks,

 

Martin

 

PS: Please also check the chapter committee membership, which is listed on the 
MPI 4.1 page of the forum website. If would like to make any changes or sign up 
for particular CCs, please let me know. Thanks!

[Mpi-forum] ACTION ITEM: Virtual MPI Forum Meetings until September

[Martin Schulz via mpi-forum]

Hi all,

 

Thanks to all for a productive MPI Forum meeting this week! I think we made 
good progress on several large items.

 

At the end of the forum, though, we ran out of time to discuss the upcoming 
virtual meetings. As we have seen in the past, these are more effective when we 
plan them long term pre-assign slots. Hence, I would like to ask everyone to 
think about whether you would like a slot until September and if so, please 
send that request to me (topic, date, speaker). The following slots are 
currently available:

 

June 15th 

June 22nd    

June 29th 

July 6th 

July 13th  

July 27th  

August 3rd  

August 10th    

August 17th

August 24th

August 31st

September 7th

September 14th (after the two week deadline) 

September 21th (after the two week deadline)

 

Please send requests early, so everyone can prepare and note this on their 
calendars.

 

Thanks!


Martin

[Mpi-forum] MPI Forum This Week!

[Martin Schulz via mpi-forum]

Hi all,

 

Just as a quick reminder: our next (exceptional voting) MPI Forum meeting is 
this week, starting tomorrow May 23 and will run until May 26. On all days, we 
will run from 9am US CT to 1pm US CT. The details, including dial in data, is 
at:

 

https://www.mpi-forum.org/meetings/2022/05/agenda

 

Note: the link is a different link specifically for this meeting.

 

On May 23 we will have WG meetings – this time, this will be in one track. The 
rough split is:

    9:00   HW Topologies

    10:00 Hybrid/Accelerators

    11:00 Sessions

However, slight shifts may occur at the common discretion of the WG leads.

 

The other three days are intended for plenaries, as listed on the agenda. We 
have several large reading scheduled we would like to get through. Hence, it 
would be good if for those readings everyone could work with the github 
versions of the PRs during the reading, so that small change suggestions can be 
made directly into the PR and will not derail the overall readings. I am sure 
the “readers” will appreciate this and it gives us a better chance to focus on 
the conceptual issues in the discussion.

 

Thanks and talk to you all tomorrow!

 

Martin

[Mpi-forum] No Virtual MPI Forum Meeting tomorrow / September dates changed

[Martin Schulz via mpi-forum]

Hi all,

 

Tomorrow’s virtual MPI forum meeting is cancelled. We will meet for the voting 
meeting the following week. The agenda is online – Monday is WG day, Tue-Thu 
plenaries.

 

Further, due to a conflict with another large event, the EuroMPI conference 
(and with that the forum) had to pushed back one week. The conference now 
starts on September 26, the MPI forum on September 28 and then runs to 
September 30. The webpages should all be updated by now.

 

See you all next week!

 

Martin

[Mpi-forum] Agenda items for May 2022 Meeting / deadline Monday (tomorrow)

[Martin Schulz via mpi-forum]

Hi all,

 

Time is flying and our next voting meeting is coming up quickly on May 23-26. 
As discussed in February, we will hold this meeting again fully virtual in the 
usual timeslots, i.e., Mon-Thu of that week from 9am to 1pm US CT. A first 
agenda draft is posted on the website, also in the usual spot.

 

https://www.mpi-forum.org/meetings/2022/05/agenda

 

Please send any requests for ballots and/or reading requests to the list by 
tomorrow/Monday and I will add them to the agenda.

 

Also, since it worked well and seemed productive, I would like to suggest to 
use the first one or two days (depending on demand and depending on plenary 
time needed) to be used for longer WG discussions. @Working Group Leads: please 
let me know if you would like a 2h or 4h block on Mon and/or Tue for this.

 

Wesley also already posted the registration link – please don’t forget to 
register in time at:

[Mpi-forum] MPI Voting Meeting Feb 28-Mar 3 2022 (next week)

[Martin Schulz via mpi-forum]

Hi all,

 

I have added the agenda for next week’s meeting onto the MPI forum website at:

 

https://www.mpi-forum.org/meetings/2022/02/agenda

 

If I forgot any issues/ballots/items, please let me know.

 

It seems, though, that we actually have a very light plenary agenda. On the 
other hand, we have currently some quite active WGs. Therefore, I am proposing 
to go back to the format from before corona and before the MPI 4.0 push, where 
we mixed longer blocks for working groups and plenary times.

 

We will meet at the usual times, as the last few voting meetings – 9am to 1pm 
US CT – but Monday and Tuesday are reserved for WGs. Currently, the Sessions WG 
is scheduled for Monday and the RMA WG for Tuesday, but we can add parallel 
sessions, if WGs would like to. Please let me know.

 

Wednesday/Thursday is reserved for plenary work – however, as the agenda is 
light, we could well be done on Wednesday (famous last words) and so I marked 
Thursday as a backup day for now.

 

Thanks and talk to you all next week,

 

Martin

Re: [Mpi-forum] Reminder: Virtual Meeting Tomorrow and Voting Meeting Soon

[Martin Schulz via mpi-forum]

Hi all,

 

Thanks to Wesley for the reminder on the items for the next voting meeting – I 
have to admit, I am currently mostly offline and hence missed that. As Wesley 
said, please send announcements today via the usual way and we will still 
include them.

 

In this vein: I would like to announce 1st readings of the following two 
issues/PRs:

 

Issue 541 / PR 647: Minor updates to the info chapter for MPI 4.1

Issue 542 / PR 646: Corrections regarding error/return codes

 

If you have any other items for the agenda, please let me know and I will add 
these next week once I am back with normal connectivity.

 

Thanks!

 

Martin

Hi all, 

 

As a reminder, we have a virtual meeting scheduled for tomorrow at the usual 
time (10 AM US Central). The topic will be a Hybrid and Accelerators Discussion 
led by Jim Dinan. The meeting information can be found here: 
https://github.com/mpi-forum/mpi-standard/wiki/Virtual-Forum-Meeting-Information.
 If that link comes up as 404 for you, make sure you’re signed into GitHub 
first and that if you’re not a member of the MPI Forum group on GitHub, you 
send me an email and I can add you.

 

Also, our next voting meeting will be on Feb 28 - March 3. Announcements for 
reading. plenaries, and votes were due yesterday, but I’m not sure if a 
reminder went out so if you can send those today, we can still add them to the 
list.

 

See all of you tomorrow!

 

Thanks,

Wes

[Mpi-forum] Update from the MPI Forum: Next MPI Meetings

[Martin Schulz via mpi-forum]

Hi all,

Thanks to all for a quite productive (and at times intense) meeting last week. 
I think we made good progress on several issues.

For those who were not there at the end, we also covered next meetings - Wesley 
already put them on the website (thanks!), but here is a summary as well:

- We decided to make the next meeting virtual again - it will be in the week of 
Feb. 28. The exact number of days and the timing will be decided again closer 
to the meeting, depending on the agenda. Expect a 9am CT start, though, and 
likely 3 or 4 hours for each day (as we had it up to now as well)
- The May meeting will be in the week of May 23rd (after the OpenMP F2F, before 
ISC and IPDPS) - this meeting will either be virtual or hybrid, with a 
preference of hybrid if we can make it work safely. In this case, we are still 
looking for organizations that can host us and that have a good setup for 
hybrid meetings. If you would be willing to be a host, please let Wesley and me 
know.

Until the Feb/Mar meeting, we will have a series of virtual meetings in our 
usual 2h slot at 10am CT on Wednesdays (starting in January after the 
holidays). To make things more easily accessible, we already specified the 
topics:

12 January, 10:00 - 12:00 - RMA Terms (Joseph S)
19 January, 10:00 - 12:00 - Logical Concurrency (Dan H) 
26 January, 10:00 - 12:00 - HW Topologies (Guillaume M)
2 February, 10:00 - 12:00 - Tools WG Topics (Marc-Andre H)
9 February, 10:00 - 12:00 - Continuations (Joseph S) 
16 February, 10:00 - 12:00 - Hybrid / Accelerators Discussions (Jim D) 
23 February, 10:00 - 12:00 - Logical Concurrency (Dan H)

No Meetings anymore in December

With that, happy holidays to all of you and see you all in the new year!

Martin

[Mpi-forum] MPI-Forum Dec. 21: No Meeting Wednesday, Next Meeting Thursday, Remaining Agenda

[Martin Schulz via mpi-forum]

Hi all,

As discussed during the meeting today, we will skip tomorrow's MPI Forum 
meeting and we will continue on Thursday in the usual time-slot 9am CT. Here is 
the remaining agenda:

- Strawpoll on next steps for the "logical concurrency" issue discussed today - 
Dan has sent the slides from today around, please take a look at them before 
the meeting on Thursday (we don't plan a long discussion, just the strawpoll 
after everyone had some time to think about it)

- Bill's discussion on "Feedback on proposed changes to the appearance of the 
code and examples"

- Joseph's two discussions on RMA topics (Issue 407 and Issue 6)

- Scheduling of the virtual meetings in the coming weeks (please let me know if 
you have any topics that you would like to lead/present/see) - I would like to 
go back to scheduling them ahead of time, for more predictable schedule planning

- Discussion on the next forum dates and locations. In June we had tentatively 
decided on 2/28-3/4 and 5/23-27 based on various constraints and conflicts, but 
we left the actual decision open on whether we want Virtual, Hybrid or 
In-Person (and in the last two options) where? 

Thanks!

Martin

[Mpi-forum] MPI Forum Agenda / No virtual meeting today or next week

[Martin Schulz via mpi-forum]

Hi all,

With the MPI Forum meeting in two weeks and no concrete topic in the queue, I 
am canceling the MPI forum meeting today and next week. If there are any 
plenary items to talk about, please let me know and I'll add it to the agenda 
in two weeks.

The current agenda is, as usual, at:

https://www.mpi-forum.org/meetings/2021/12/agenda

Note, we only have one ballot scheduled this time, so - assuming there are no 
no-no votes necessary - we'll do that on the first day in the indicated voting 
block.

In general, the agenda seems pretty compact this time, which is not unexpected 
as many MPI 5 discussions are going on in the WGs - if I missed anything please 
let me know. Due to this I already reduced the time slightly to 3 hours per 
day. My suggestion is to simply start on Monday, as indicated and then we'll 
see how much we get done on that day - after that we can schedule the remaining 
days as needed.

Hope this sounds OK to everyone,
Talk to you all in about two weeks,
Thanks,

Martin

[Mpi-forum] Deadline for MPI Forum Announcements TODAY (11/22)

[Martin Schulz via mpi-forum]

Hi all,

We are already only 2 weeks away from the next MPI Forum meeting, which we 
decided to hold virtually over Zoom again.

Therefore, please
- Register at https://forms.gle/FYUSaHSqaL1uwEEv8
- Announce any readings, errata ballots, regular ballots to this list by the 
end of today (Monday 11/22)

Also, if there are any other plenary topics a working group would like to 
cover, please let Wesley and me know. Based on the input, we will create an 
agenda, which is then - as usual posted - on the forum website. We currently 
have four days earmarked with up to 4h each day - we'll see based on the 
suggested agenda items how much of that we actually want to use.

Thanks!

Martin

Re: [Mpi-forum] mpi info behavior

[Martin Schulz via mpi-forum]

Hi Ken,

To my understanding, this is actually a bug in the MPI library or an incorrect 
implementation according to the standard. We had a very lengthy discussion 
about this during MPI 4.0 - here is a link to the issue:

https://github.com/mpi-forum/mpi-issues/issues/63

We had in there at some point the following principles that guided the new text:

Principles:
a) the key/value pairs returned by MPI_GET_INFO must always have been supplied 
by the user and not ignored by the MPI library
b) the semantics of supplying an INFO during object creation and during 
MPI_SET_INFO should be identically defined
c) the MPI is permitted, but not required, to 'ignore' any INFO key/value pair 
supplied by the user
d) if an INFO key/value pair is ignored by MPI, then it will not appear in 
subsequent MPI_GET_INFO calls
e) if an INFO key/value pair was not ignored by MPI, then it must appear in 
subsequent MPI_GET_INFO calls

(the same was then applied to all get infos)

d) seems to be the key aspect here. From what I remember, this was a deliberate 
choice, as the assumption back then was that the user wanted to know what the 
library actually did with the info (and a library was allowed to not store 
other values that are not used). Also, we allowed the return of a different 
value - if a library knows and uses the key "foo", but only uses the first 
character, the value returned would be "b" - again with the idea that the user 
wants to know what is used.

We had actually discussed a second version of MPI_Get_info that would return 
the actual user supplied values, but we never pursued that - perhaps it is 
worth reconsidering this again.

Martin

Here's an example program that illustrates the current file info behavior 
with MPICH and Open MPI. Neither library will abort the application in my 
tests. MPICH does not recognize the "foo" key, and I would guess the same for 
Open MPI.

So is this correct behavior according to the standard? Or a bug? There are 
users who prefer the current behavior, I suspect in part because there is no 
attribute caching interface for MPI file objects.

We brought this to the forum because during our internal discussion is 
was shown that ROMIO will return any "ignored" key/value pairs set by the user 
in MPI_FILE_GET_INFO. Essentially, ROMIO duplicates the users info object, and 
only adjusts settings for keys it recognizes. Perhaps this is wrong behavior 
according to MPI-4.0?

This behavior was introduced into ROMIO somewhat recently in May 2020. 
There was a user request for it based on how OMPI-IO behaved.

Hi Rob,
This seems reasonable to me. I think you can draw an analogy to an 
application setting "mpi_assert_no_any_tag = true" and checking the value 
returned by MPI_Comm_get_info to decide whether to use MPI_ANY_TAG on the 
communicator. I would suggest info values like "true" and "false" so that ROMIO 
can return back the same value passed by the user if the info key is accepted.

As of MPI 4.0, MPI_File_get_info must return "all hints that are 
supported by the implementation and have default values specified; any 
user-supplied hints that were not ignored by the implementation; and any 
additional hints that were set by the implementation." So, true/false would 
also allow ROMIO to return a default value for the info key if the user hasn't 
set it.

One thing you can't do with info today is fail the operation 
because of a key/value pair in the info argum

[Mpi-forum] FW: No MPI Virtual Forum Meeting Today

Hi all,

We again don't have a particular topic for today and hence I am canceling the 
meeting. However, please take a look at the project board and see if you have 
an issue assigned to you and/or if there is something in a WG you are part of 
that should be pushed forward. Here is a link to the board:

https://github.com/mpi-forum/mpi-issues/projects/3

In particular, it would be great of all Chapter Committee leads could look at 
the issues labeled "All CCs Must Check"

https://github.com/mpi-forum/mpi-issues/projects/3?card_filter_query=label%3A%22all+ccs+must+check%22

and see if the changes for the respective chapter is still missing for that 
issue.

Thanks!

Hi all,

We'll have no virtual MPI Forum meeting today - so far, no forum wide 
discussions are ready from the side of the WGs and there wasn't much progress 
in direction of MPI 4.1, yet.

For the latter, please take a look at the project board and see if you have an 
issue assigned to you and/or if there is something in a WG you are part of that 
should be pushed forward. Here is a link to the board:

[Mpi-forum] No Meeting Today

[Martin Schulz via mpi-forum]

Hi all,

Since I noticed some logins into Zoom: after the last full voting meeting, we 
said that we would skip for 2 weeks and then pick up again (at least I 
thought/hope we did). Sorry if there was any confusion.

If there any particular topics for next week, please let Wesley and me know - 
otherwise, we'll use next week to continue to push on MPI 4.1 (or pick up 
left-over topics from the last meeting).

Thanks!

Martin

[Mpi-forum] EuroMPI Starts Today, MPI-Forum starts Thursday, Joint Session on Wednesday

[Martin Schulz via mpi-forum]

Hi all,

Just as a quick reminder, EuroMPI and the MPI Forum will be this week, with a 
joint session between the two on Wednesday (more below). If you haven't 
registered, yet, please do so at https://www.eurompi21.lrz.de/ - registration 
is free!


EuroMPI 2021 


EuroMPI 2021 starts today with a keynote by Olga Pearce and several paper 
presentations plus a poster/open discussion session. Tomorrow (Wednesday) we 
will have two topical sessions on RMA and MPI Sessions where we will look into 
the future of these two important concepts - more on this below. The conference 
will run 9am to 1pm US CT each day.


September MPI Forum
=== 

Starting Thursday we will transition into the MPI Forum starting on Thursday 
with plenary discussions, mainly focusing on MPI 4.1 - the agenda is at 
https://www.mpi-forum.org/meetings/2021/09/agenda. The forum will run 9am to 
1pm US CT each day.


Joint Session on Wendesday
===

In the spirit of bringing EuroMPI closer to the activities of the MPI Forum, we 
will use the second day of EuroMPI to discuss perspectives on two important 
topics for MPI 5.0: RMA and Sessions - for each topic we will have a separate 
session starting with a vision talk by Bill Gropp for RMA and Dan Holmes for 
Session, followed by three paper presentations on these topics, and then an 
interactive panel discussion. While officially part of EuroMPI, this will also 
guide discussions in the forum - therefore, we also invite all Forum 
participants to join us in this session (please register for the conference to 
get the link - it is free!)


Looking forward to seeing/hearing you all this week!

Best regards,

Martin

Re: [Mpi-forum] Questions on MPI Standard formatting

[Martin Schulz via mpi-forum]

Hi Bill, all,

 

I also agree with what has been said so far and I also agree with the statement 
that if we don’t find a good solution for tables, leaving it off there is not a 
big problem (lines should be easily identified there.

 

As for the syntax highlighting – I personally don’t mind it sticking out, but I 
can also see Joseph’s point – perhaps something between the two version would 
work.

 

One question, though: in the example that goes over two pages, the 
“MPI_Waitsome” call is only bold for “MPI_Wait” and not bold for “some” – is 
this an annotation bug or a problem with the package of not detecting prefixes 
correctly?

 

Thanks!

 

Martin

I am in agreement with all that has been said so far -- generally, this is 
great.  Minor tweaks (already cited by George and Joseph) would be nice 
improvements.

One option is to use a different font; the one I used in the first examples has 
a strong bold.  Here’s the same page with a different font with a less bold 
look. In some ways, this may go too far in the other direction - the bold text 
is a little heavier, but the difference is slight. 

 

One advantage of this choice is that the code text is not quite as wide as with 
the font choice for the previous example, which works better with the current 
code examples.

 

Let me know your preference.  It is easy to change, modulo the issue of needing 
to wrap a few lines of code.

I am OK with leaving out line numbers in tables. Maybe that will be solved in 
the future.

One comment I had was on the code formatting. While I definitely prefer the 
lstlistings formatting over the verbatim we have so far, I find the bold 
highlighting somewhat distracting. I find it hard to focus on the surrounding 
code pieces. Would it be possible to tone down the highlighting somewhat 
(slightly thinner, maybe grey)?

Thanks
Joseph

Thanks, George.  On the line numbering, unfortunately, this is very difficult 
to fix (and is a known problem). My proposal instead is to not use the line 
numbers in these cases; in the rare cases where we need to identify the 
location, we can count rows in the table or otherwise identify the line. There 
are some alternatives, but they are awkward and IMHO ugly, and don’t add much.

Bill,

These PDFs looks great, a clear leap forward in improving the readability and 
cleanness of the MPI standard.

The only issue I noticed (and that was pinpointed in your email) was about the 
multi-page tabular where the numbering is done consecutively for the entire 
tabular environment despite the fact that the table is split across multiple 
pages, and the numbers are placed on the same side as the first page on all 
pages. If we can fix this to have the line numbers per page and on the correct 
side for all environments, that would be great.

Thanks,
  George.

   I’ve been experimenting with updating the MPI Forum document
   formatting, and in particular, modernizing the use of LaTeX and
   reducing the custom LaTeX in the document. Attached are a few
   pages from my tests.  These show:

   1) Use of the lineno package to label each line of text - this
   replaces the ruler currently used, and means that text is more
   accurately labeled, but “boxes”, including tables, figures, and
   captions may not have line numbers. All of the attached pages
   show the line numbers in the margins.
   2) Use of the lstlisting package, with syntax and MPI routine
   highlighting. This also sets a background to gray to help the
   code examples standout. The approach used in MPI 4.0 creates a
   box with a border; because of the box, in that approach, the
   individual lines of code are not numbered.  Hence this change in

[Mpi-forum] MPI Virtual Meeting / EuroMPI / MPI-Forum September Meeting

[Martin Schulz via mpi-forum]

Hi all,

Just a few reminders:

- We have our next MPI Forum Virtual Meeting tomorrow (Wednesday 8/25) at the 
usual time of 10am US CT (link on github). The agenda is to continue 
discussions on changes for MPI 4.1. In particular, Bill is planning to discuss 
a few items from his editorial pass(es).

- EuroMPI registration is open and registration is free. As last year, the 
conference is virtual.  I think we have an exciting program over the two days, 
September 7th and 8th (from 9am US CT to 1pm US CT), which will also bleed over 
to the MPI forum with RMA and Sessions discussions on Day 2. More information 
on https://www.eurompi21.lrz.de/. Please help spread the word.

- The MPI-Forum on September 9th and 10th (also virtual, also 9am US CT to 1pm 
US CT) is getting close and this Thursday is the two week deadline for plenary 
announcements (readings, erratas, regular ballots). I already saw some going 
around - if there are any others, please post them to the email list. If there 
are any other items you would like to see on the agenda, please let me know as 
well.

- We have a combined registration for both events (thanks to Wesley!), which is 
at https://forms.gle/vJ32yJqNxe2DCUxC7 - if you plan on attending either one, 
please register as soon as possible.

Thanks!

Martin

Hi all,

Since we don't have any particular topic lined up, we'll have no MPI Forum 
virtual meeting today (8/18). The next meeting will be next Wednesday - we'll 
again talk about minor clean-up issues for MPI 4.1. Specifically, Bill has 
several items he would like to go through. If there are other topics, please 
let Wesley and me know.

Thanks!

Martin

[Mpi-forum] Reminder: MPI Forum Virtual Meeting today (8/11) at 10am CT

[Martin Schulz via mpi-forum]

Hi all,

Just as a quick reminder: we will have our usual MPI Forum Virtual Meeting 
today (usual time 10am CT, usual spot - link on github). The topic is a reading 
of the minor fixes in Chapter 3 (Pt-2-Pt), with a discussion on how we want to 
fix terminology. The results from today are intended as blue prints for the 
remaining chapters.

Thanks,

Martin
