Any information is good information. The lack of information about
verbs / RDMA is definitely a hinderance.
It would also be good to scrub all the old / useless / incorrect
information that is out there. I believe there's a ton of outdated
information on the wiki with no real indication that it's old /
outdated (I see "Install OpenIB for Ammasso1100" right on the front
wiki page).
As Gus mentioned, even a low-hanging-fruit FAQ (that is actively
maintained -- that's the killer) would be useful.
Screencasts are good; those are an easy way for developers to
broadcast info to the world.
Programming guides are noticeably missing; you probably want several,
ranging from "explaining the basics" to "advanced programming".
Videotaping humans giving tutorials are good, too. Those can be
easily web-hosted somewhere.
Like I said, any information is good information. But to do it right,
you really need one or more full-time people doing this stuff (IMHO).
And no, I'm not volunteering. :-)

I support the idea of the RDMA tutorial. Beyond the “meat” as
described below, I would encourage the tutorial to include a “how to
program RDMA” section. While OFA Verbs provides a rich set of
mechanisms, it is difficult for the average programmer to get a
solid handle on how to use the capabilities, register memory, …
Some cookbook examples, or perhaps development of several
programming “patterns” can go a long way to having RDMA become a
much more mainstream application programming paradigm.

Keep me in the loop.
I am interested to do it also.

Richard, Andy,
Thanks for copying me Richard. I had not seen Andy's email on the
general
list.
Figuring out how to get tutorial and other documentation created and
published in the list of things to get done in 2009 for me in my
part-time
role as Exec. Dir.
There is no funding set up for this at the moment but I believe
there will
be in about 30 days.
That's because I'm thinking that we can get funding for this by
making it
part of the funding for a new marketing plan for OFA that, with Wayne
Augsburger and Jim Ryan, we are preparing for the OFA Board to vote
on at
the next con-call meeting which is on May 20 at 9.00AM PDT.
Would you be willing to work with me and create a small team from
others
within OFA who have the same interest to prepare a description by
May 20 of
what the tutorial would look like, who would contribute to it, how
to get it
"polished up" for web and/or book style publication, what the
overall costs
would be, etc.
My thoughts, that could be a starting point for the team's work, are
that we
would make the creation a collective effort.
The tutorial would have several sections for example general intro,
benefits
of RDMA, applicability in HPC and Enterprise, networking background
etc.
Members of the Marketing Working Group would be responsible for this.
The "meat" would be sections for kernel level things (verbs etc.),
then user
space things (verbs etc.), then APIs like MPI, SDP, EDS etc. - each
section
overseen by the technical leaders/maintainers of the code within OFA
for
that section (for Example Tom Talpey for NFSoRDMA, or you Richard
for RDS)
Finally the tutorial would have sections about Interoperability
Testing that
OFA/IOL does but also what customers can do on there own systems -
Arkady
and Rupert and IOL have put in an SC09 tutorial proposal that we could
leverage in this section.
To all readers of this email:-
If you have read this far, please give us all some feedback. If you
have
material you'd like to contribute please say so. If there's a better
way,
tell us what you think it is!
Thanks,
Bill.

Andy, I saw your postings to ofa-general on this and I agree it
would be
great to have this documentation.
As OpenFabrics is really about RDMA... we need to make it simpler
for folks to pick up and run with RDMA concepts ...vs.. digging thru
the IB
specs and code examples, etc.
Let's see what Bill Boas thinks...perhaps OFA has a writer on board
that
can help us do this..?
I can also help provide input for a new OFA RDMA tutorial doc..
