binding tool docs?
by Jeff Hammond 30 Nov '21

30 Nov '21

I can't figure out how to use the binding tool. Running various Python scripts with -h hasn't helped me. Is there any documentation, or can someone point me to a working example that I can inspect? Thanks, Jeff -- Jeff Hammond jeff.science(a)gmail.com http://jeffhammond.github.io/

Dear MPI User, the MPI Shared Memeory interface is an interesting extension of MPI. "One-Sided Communication and the MPI Shared Memory Interface" on FutureLearn: https://www.futurelearn.com/courses/mpi-shared-memory-interface/1 You can start now - it is free: Weeks 3 (just started) and 4 are dedicated to this fascinating functionality for efficient parallel programming on clusters of multi-core shared memory nodes. This online course will will run in total for four weeks, with an estimated effort of 4 hours per week. During this time you will be guided through the concepts of MPI one-sided communication and learn how to correctly and efficiently use MPI shared memory (with C and Fortran bindings). Several examples and exercises will illustrate the use of these features and help to understand their benefits. You will also be able to challenge your knowledge with some quizzes! This online course has been developed by us, i.e., by HLRS, ASTRON and SURFsara, with the sponsorship of PRACE. You can register for free via FutureLearn using the link above. Best regards, Rolf Rabenseifner, Lucienne Dettki, Zheng Meyer-Zhao, and Carlos Teijeiro -- We would appreciate if you could forward this email to interested colleagues.

Hello all, I would like to have a plenary/discussion on the current and potentially future Pythonization infrastructure. Taking into account the work by Hui Zhou, Ken Raffenetti, Wesley Bland and Yanfei Guo from the EuroMPI21 publication. Thanks, Martin Ruefenacht On 22.11.21, 01:27, "mpi-forum on behalf of Martin Schulz via mpi-forum" <mpi-forum-bounces(a)lists.mpi-forum.org on behalf of mpi-forum(a)lists.mpi-forum.org> wrote: Hi all, We are already only 2 weeks away from the next MPI Forum meeting, which we decided to hold virtually over Zoom again. Therefore, please - Register at https://forms.gle/FYUSaHSqaL1uwEEv8 - Announce any readings, errata ballots, regular ballots to this list by the end of today (Monday 11/22) Also, if there are any other plenary topics a working group would like to cover, please let Wesley and me know. Based on the input, we will create an agenda, which is then - as usual posted - on the forum website. We currently have four days earmarked with up to 4h each day - we'll see based on the suggested agenda items how much of that we actually want to use. Thanks!

MPI Forum Agenda / No virtual meeting today or next week
by Martin Schulz 24 Nov '21

24 Nov '21

Hi all, With the MPI Forum meeting in two weeks and no concrete topic in the queue, I am canceling the MPI forum meeting today and next week. If there are any plenary items to talk about, please let me know and I'll add it to the agenda in two weeks. The current agenda is, as usual, at: https://www.mpi-forum.org/meetings/2021/12/agenda Note, we only have one ballot scheduled this time, so - assuming there are no no-no votes necessary - we'll do that on the first day in the indicated voting block. In general, the agenda seems pretty compact this time, which is not unexpected as many MPI 5 discussions are going on in the WGs - if I missed anything please let me know. Due to this I already reduced the time slightly to 3 hours per day. My suggestion is to simply start on Monday, as indicated and then we'll see how much we get done on that day - after that we can schedule the remaining days as needed. Hope this sounds OK to everyone, Talk to you all in about two weeks, Thanks, Martin -- Prof. Dr. Martin Schulz, Chair of Computer Architecture and Parallel Systems Department of Informatics, TU-Munich, Boltzmannstraße 3, D-85748 Garching Member of the Board of Directors at the Leibniz Supercomputing Centre (LRZ) Email: schulzm(a)in.tum.de
