PMIx, EasyBuild Tech Talks

[deliciouslytyped]

@boegel was there ever a recorded talk by Ralph Castain about PMIx as mentioned at https://youtu.be/U_xC6L1f3B8?list=PLhnGtSmEGEQhK-qmBEM-tg4AiwBOcm5k1&t=298 ? (" EasyBuild Tech Talk I - The ABCs of Open MPI, part 3 (by Jeff Squyres & Ralph Castain) ")

@deliciouslytyped No, not to this point, it never materialized...

Totally fell off my radar - I'm in the process of moving, but I'll add it to my list of things to do and try to get to it soon. Thanks for the reminder!

@rhc54 Any updates? :)

Maybe now is a better time even, with the recent release of PMIx v5.0...

[rhc54]

Sigh...my apologies. The move has been drawn out and difficult, death in the family, trying to slow down in retirement, etc. I'll try to put something together over the next month.

Appreciate the patience and friendly reminders 😄

@boegel Would you be interested/willing to setup another EasyBuild meeting for me to present this? Would be easier for me if you could record/post it, and make it more interactive. Are there specific topics/questions people would like me to address?

[boegel]

@rhc54 That would certainly be interesting to have an EasyBuild Tech Talk on this.

Do you mind sending me an email about that? I'm bound to overlook replies in issues, since I have notifications disabled for that due to too much noise...

Hey folks, any news on this? I assume it's gone somewhere in the pile... ;)

Not sure if slides or documentation already exists, but if that do that would be helpful already.

[rhc54]

Oh my - yes it did fall off the radar as I began to make a concerted effort to actually (finally) retire. I have been greatly reducing my effort as a result. However, that doesn't change the fact that I promised to do this and have so far failed - which is disturbing.

There is documentation out there, but I can/should provide the talk to supplement it. I probably forgot to send @boegel an email as requested. I'll do that now and try to follow thru.

Thanks for the reminder!

Ping? :)

[rhc54]

Sorry for the silence - I exchanged some emails with Kenneth et al shortly after your initial "ping". With planned holidays, we agreed to do this talk sometime in 2nd half of Aug or perhaps early Sept. I don't think we settled on an actual date before folks left for vacation, but it shouldn't take long to resolve once they return.

Plan is:

I can talk about the rather large architectural change in OMPI v5 to focus solely on PMIx (dropping PMI-1 and 2 completely) and switching to use PRRTE as their RTE (and dropping their embedded ORTE). I can also talk about the new features in OMPI as they rely on new PMIx/PRRTE capabilities, and how people are using the scheduler integration to study malleable applications. Finally, can talk a bit about project directions given my "retirement".

Feel free to suggest additional/alternate topics!
