Re: [mpiwg-tools] Meeting reminder: Sep 15, 2025 (Performance Topics)

Dear all, I totally forgot about a topic that Martin asked me about at ISC. Anna-Lena-Roth of University of Applied Sciences Fulda asked about a use case for tracking and mapping Requests using MPI_T and the challenges with that. Anna-Lena will also join us today, so we can discuss this topic to see whether this is also something we'd like to bring up as a plenary topic in Charlotte (because direct feedback from vendors could prove very helpful).

Nope. > - Which topics is advanced enough to benefit from plenary discussion? MPI_T semantics need, IIRC, some concrete answers from implementors (and other interested users): * Can peruse-like events be collected in MPICH without terrible pain? * If so, can MPICH and OMPI agree on common semantics that are implementable in both? * Will reserving, e.g., the “MPI_T_*” namespace for events/pvars/cvars with common semantics specified in a side doc be unreasonably limiting? * Are there things besides peruse that count as low-hanging fruit here? QMPI needs, ultimately, the static/dynamic tool list decision (from MPI’s perspective). Everything else is IMO _mostly_ settled, but we really can’t write a reasonable chapter without knowing how much flexibility we’re requiring implementations to support. > - Which timeslots are best suited? > Earlier in the day is better for me, but my afternoons/evenings (CEST) are pretty clear that week. > As I basically just returned from sick leave I did not get any work done, so would not have anything further to discuss today. > > Does anyone of you have a topic to discuss? > Nothing beyond the above. > Cheers, > Marc-Andre > -- > Dr. rer. nat.

Plenary time at Charlotte meeting?
by Marc-André Hermanns 18 Aug '25

18 Aug '25

Hi all, I don't know who will be at the Charlotte meeting in September (I will not), but we should discuss whether it makes sense to have some plenary time for our topics. - Who plans to attend the meeting in person? - Which topics is advanced enough to benefit from plenary discussion? - Which timeslots are best suited? As I basically just returned from sick leave I did not get any work done, so would not have anything further to discuss today. Does anyone of you have a topic to discuss?
