主题: [alto] Presenting ALTO-related work at MOPS WG on Friday

Dear ALTOers,

For those interested, next Friday at MOPS WG I will have the opportunity to 
present the work in Telefonica for the integration of ALTO as a way of exposing 
topology information to Telefonica CDN.

The session is entitled “Exposure of Telefonica network topology through ALTO 
for integration with Telefonica CDN” 
(https://datatracker.ietf.org/meeting/114/materials/agenda-114-mops-02.txt).

Best regards

Luis

Re: [alto] IETF 114 ALTO Hackathon projects

2022-07-25 Thread Mario Lassnig

Hi everyone,

just came back from holidays. This is fantastic news, and a big thank
you to the people who invested so much of their time.

I'm really excited to try out the new algorithm for ATLAS.

Cheers,
Mario

Hi Mihai, Steve, Mario, all,

This is an update on the IETF hackathon which just finished today
(July 24) in Philadelphia, PA. Mahdi presented the results to the
whole hackathon audience at slightly over 2 pm on behalf of the team.
The initial integration of ALTO and FTS and the zero-order algorithm
are fully functional (at least in the concurrent setting).

This excellent progress is the result of hard work that takes a
village; Jensen stayed up 24 hours non-stop until 2 pm to finish up
the FTS production code integration framework, Mahdi was sleeping only
4 hours per day in consecutive days to implement the full zero-order
gradient algorithm, Kai and his team made great progress on
implementing openalto with both standard features (path vector) and
next step features (FCS), and the team worked under the great
organization of Jordi. We plan to do some more demos and socials
tomorrow (Monday) at the IETF Happy Hour to try to get more IETF
feedback. The working slides are at:
https://docs.google.com/presentation/d/1CcCMvZ_SeWLRAN32Qz8RFcHrF8spAu_6/edit?usp=sharing&ouid=110882839032059047983&rtpof=true&sd=true

As soon as the IETF this week is over, we will schedule an overall
group meeting to go over the technical details, and plan for the next
steps. I consider HTTP a great example of a hugely successful
collaboration between the networking community (IETF) and the data
sciences (CERN). Let's use this project to promote collaboration
between these two communities again.

Cheers,

Richard for the team

Hello Richard,

I'll summarize my answers from the other thread.

Unfortunately, due to other arrangements, we won't be able to
attend the hackathon this weekend.

However, we are very excited about the proposed objectives. We
already established a way for the FTS Optimizer zero-order
algorithm to make it's way into production. Once the feature is
ready, with the help of Mario, we can organize a large-scale test
and compare the results we get in production with the simulated
results.

On further ALTO and FTS integration, one aspect I see particularly
promising is:
1. Use ALTO information to assess the network capability of a
given RSE
2. Set a maximum limit for how much network percentage FTS can
occupy. In a feedback loop via ALTO, FTS would find whether it may
increase or should decrease traffic involving that RSE

This maps directly to what we see in production: FTS can hit some
sites too hard.
Any extra knowledge FTS gets on this aspect would allow it to
improve.

Best Regards,
Mihai for the FTS team

Hi all,

During the weekly ALTO meeting today, we discussed the coming
hackathon and Qin suggested that we send an update to the mailing
list on the FTS+ALTO project, and here is the update:

- In short, if you want to work on ALTO integration
with production, open projects, this can be a wonderful project
to work on: it may help both ALTO (in terms of its crucial
deployment mandate) and the largest data-intensive science
projects at CERN.

Specifically:
- For those who have not tracked the hackathon, as Jordi said, it
is a continuation of the 113 Hackathon. In particular, the 113
Hackathon focused on the integration with Rucio, which is a
wonderfully designed tool used widely in CERN and some
other projects for data movement of a large amount of data (PB ->
EB). In 113, the hackathon modified the manual workflow, which is
the workflow to select the source to download a dataset when a
client issues a download command. The other workflow of Rucio is
the automatic workflow, which selects the sources and
destinations to realize user-specified replication rules. In our
original plan, 114 would focus on the automatic workflow.
However, the team realized that Rucio is built on top of FTS,
which is the main tool used at CERN to schedule which transfer is
scheduled at what time, where Rucio is at a higher layer
providing the transfers for FTS to schedule.

- The 114 hackathon includes 2 objectives: (1) introducing
resource control to FTS, and (2) evaluating an alternative design

so.

When: Mon july 25, at 7:30pm EST
Where: Maggiano's Little Italy. It's a 14' walk from the Sheraton. Directions: 
https://goo.gl/maps/n14tiEGEYvCZdsJfA
Optional: Come to the Sheraton Lobby at 7:10pm to start walking towards the 
restaurant at 7:15pm. Otherwise, you can go directly to the restaurant.

That's great to hear Richard.

And great thanks to the team.

Hello Richard,

I'll summarize my answers from the other thread.

Unfortunately, due to other arrangements, we won't be able to
attend the hackathon this weekend.

This maps directly to what we see in production: FTS can hit some
sites too hard.
Any extra knowledge FTS gets on this aspect would allow it to
improve.

Hi all,

During the weekly ALTO meeting today, we discussed the coming
hackathon and Qin suggested that we send an update to the mailing
list on the FTS+ALTO project, and here is the update:

resource control to FTS, and (2) evaluating an alternative design
of FTS core: the FTS Optimizer. Hence, the work includes 3
components, integrating the FTS production code and framework:

Hi Mihai, Steve, Mario, all,

This is an update on the IETF hackathon which just finished today (July 24)
in Philadelphia, PA. Mahdi presented the results to the whole hackathon
audience at slightly over 2 pm on behalf of the team. The initial
integration of ALTO and FTS and the zero-order algorithm are fully
functional (at least in the concurrent setting).

This excellent progress is the result of hard work that takes a village;
Jensen stayed up 24 hours non-stop until 2 pm to finish up the FTS
production code integration framework, Mahdi was sleeping only 4 hours per
day in consecutive days to implement the full zero-order gradient
algorithm, Kai and his team made great progress on implementing openalto
with both standard features (path vector) and next step features (FCS), and
the team worked under the great organization of Jordi. We plan to do some
more demos and socials tomorrow (Monday) at the IETF Happy Hour to try to
get more IETF feedback. The working slides are at:
https://docs.google.com/presentation/d/1CcCMvZ_SeWLRAN32Qz8RFcHrF8spAu_6/edit?usp=sharing&ouid=110882839032059047983&rtpof=true&sd=true

As soon as the IETF this week is over, we will schedule an overall group
meeting to go over the technical details, and plan for the next steps. I
consider HTTP a great example of a hugely successful collaboration between
the networking community (IETF) and the data sciences (CERN). Let's use
this project to promote collaboration between these two communities again.

Cheers,

Richard for the team

Hi all,

Confirming that I have made reservations for the restaurant Maggiano's Little 
Italy. However, in order to accommodate all of us, I could only find a table at 
7:30pm, hope that time works for all of you who accepted.

Here are the coordinates:

When: Mon july 25, at 7:30pm EST
Where: Maggiano's Little Italy. It's a 14' walk from the Sheraton. Directions: 
https://goo.gl/maps/n14tiEGEYvCZdsJfA

If anybody else wants to attend who still has not confirmed, we should still 
have a bit of room to have you.

Looking forward to seeing you all there.

Jordi

Thank you for confirming those of you who have. I am looking into making 
reservations to this restaurant:

  *   Maggiano's Little Italy

which is nearby the Sheraton and appears to have a wide variety of foods to 
accommodate for different preferences. Attached the menu. Please let me know if 
you'd like me to look for somewhere else otherwise.

Thanks,

When: Tuesday, July 26, 2022 1:00 AM-4:00 AM.
Where:

Sending this invitation to block the calendar for those ALTOers who will be in 
Philadelphia.

We will make a reservation to a restaurant for dinner once we confirm the full 
list of attendees. This is an informal gathering/meal outside the official IETF 
114 meeting events so that we can spend some time together. The dinner is of 
course optional though we encourage your attendance. Each of us will need to 
cover for the cost of the meal.
