Meeting Notes
by Jim Dinan 30 Sep '21

30 Sep '21

Hi All, I did some housekeeping on the wiki and posted notes from yesterday's meeting. I encourage WG members to take full advantage of this being a wiki. Please do feel free to add to and improve upon the (somewhat sparse) notes I took yesterday. After each discussion, we should try to clearly capture any conclusions that were reached, open items, and next steps for proposal authors. I didn't create a spot for it, but it would also be easy to create wiki pages for individual proposals if proposal leads feel it would be helpful. https://github.com/mpiwg-hybrid/hybrid-issues/wiki Please send topics for our next meeting. Otherwise, our standing agenda will be to spend time on each of the active topics [1]. I'll work on updating our private fork of the MPI standard git repository next and share an update when that is ready for hosting PRs of work in progress. Best, ~Jim.

Fwd: [mpiwg-persistence] HACC WG This Wednesday

Sorry, the email went to the persistence mailing list only... -------- Forwarded Message -------- Subject: Re: [mpiwg-persistence] HACC WG This Wednesday Date: Tue, 28 Sep 2021 18:59:05 -0400 From: Joseph Schuchart <schuchart(a)icl.utk.edu> To: mpiwg-persistence(a)lists.mpi-forum.org Hi all, On 9/27/21 11:40 AM, Jim Dinan via mpiwg-persistence wrote: > Hi All, > > This Wednesday, the HACC WG will meet and discuss: > > 1) Message ordering in the case of multiple threads (#117). I put my proposal for turning the disputed paragraph into a short AtoU up at [1] so we can work on it during the meeting. If someone has a better idea for how to organize this out of the eye of the broader forum please let me know. > 2) The draft continuations proposal. I'm attaching the current PDF (which is similar to the one I sent out a while ago). The github diff can be found at [2]. We had some internal discussions about changing the current proposal and found that the lack of a compelling use-case for multiple continuations doesn't help in justifying the added complexity and overhead. We will go with the current version of it.

Hi Jim, all, From my point of view, there are two topics to discuss: 1) The question of message ordering in the case of multiple threads (#117). 2) The draft of my continuations proposal. I had a quick conversation about it with Dan during EuroMPI and I believe the API in the proposal can be improved by making a few tweaks (mainly to allow for multiple continuations to be attached to the same request). I won't have enough time to implement my ideas in the next couple of weeks to see whether it can be done efficiently but I'd like to present them to get feedback from the WG. If there are no other topics, I'd like to take 15-30 minutes to discuss the changes to the API and then we can continue to talk about the multi-threaded message ordering issue.
