[mpiwg-hybridpm] Hybrid WG Meeting

[Jim Dinan]

Hi All,

Quick reminder that the Hybrid WG will meet from 10:30 - 12:00 on
Wednesday, Sept 28. Please note, that we are *not* using our usual zoom
meeting. This meeting will be hybrid in-person and remote using the MPI
Forum's zoom session.

Agenda for this meeting:

(1 hour) Review proposals for integrating MPI communication with
accelerators


(1) MPIX_Queue as a new MPI object (Naveen)
(2) MPIX_Queue as arguments to a function (Jim)
(3) MPIX_Stream (Hui)
(4) MPI Streams (Quincey)

(15 min) Review questions captured and pro/con
(15 min) Discuss approach we can use to reach a common proposal

Common evaluation criteria (e.g. implementation targets, application usage
models, etc.)


Each speaker will have 15 minutes to present their approach. During this
time, I would like to capture questions and pro/con so that we can use the
final half hour for review and analysis. We will use a shared Google
Document [1] to capture these notes and ask that we keep speaker
interruptions to a minimum. Please open the document link below and click
"Request Edit Access" if you would like to contribute to notes during the
meeting.

Look forward to tomorrow's discussion,
 ~Jim.
