Hi all, Based on the availability of speakers, I have uploaded a revised agenda: The WG time on Monday is cancelled – to avoid confusion we will start the plenary still at 11am CT. Tomorrow (Tuesday) will be dedicated to WG time – currently Tony has scheduled a slot for the collectives/partitioned, but other WGs are welcome to use the slot as well – WG chairs, please send out separate zoom links for your sessions The rest is as indicated on the agenda – plenaries will be Monday and Thursday (with the ABI being scheduled for Thursday first thing) Thanks!

Re: [Mpi-forum] MPI Forum Next Week

I will provide an update on the MPI ABI discussions, including: 1. Why we need MPI_<handle>_{to,from}int instead of f2c/c2f in the C API in order to support Fortran in a non-stupid way. This is completely noncontroversial and makes the C API better since apparently even C++ users are using f2c/c2f to "(de)serialize" handles. 2. Why we need new callbacks to support third-party language bindings (including Fortran in an implementation-agnostic way). This is useful both for Vapaa and mpi4py. There's one unsolved issue to discuss. 3. Why we need some sort of sentinel registration. This addresses the hackish way the C implementation knows what MPI_IN_PLACE, .e.g, is in Fortran. 4. Why we need Fortran datatype registration. Basically, the Fortran API tells the C API the mapping from Fortran to C types so the C implementation doesn't need to know how the Fortran compiler works. There might need to be an init hook here since it is legal to initialize MPI from C and then use Fortran features. https://urldefense.us/v3/__https://github.com/pmodels/mpich/pull/6953__;!!G… and https://urldefense.us/v3/__https://github.com/pmodels/mpich/pull/6965__;!!G… have some discussion. You don't have to read these or the thousands of Slack messages if you don't want, as the purpose of this plenary is to summarize the situation and get guidance on the text changes I should make.

MPI Forum Next Week
by Martin Schulz 11 Jun '24

11 Jun '24

Hi all, We have our next MPI Forum meeting scheduled for next week, at the usual times for virtual meetings from 9am to 1pm CT on Monday, Tuesday and Thursday (as Wednesday is a US holiday that we seemed to have missed when scheduling this). My apologies, though, for not sending a reminder for this – I have to admit, this sneaked up on me a bit quicker than I thought and I did not see this in time to catch it at the 2 week mark. Unfortunately, no-one else happened to catch this either, which now leaves us with only ballot item, the change of rules we discussed last time. Wes and I thought about whether we could mitigate this with a “creative” use of no/no votes, but we both quickly came to the conclusion that would not be in the spirit of the forum and the rules and, hence, would like to refrain from this. Nevertheless, we can and should still use this meeting to make progress on some the larger points, in particular the ABI text. With the timeline for (what we commonly expect to be) MPI 4.2 not set, this should actually not set us back in time. Therefore, if you have any particular items, you would like to have on the agenda, please let Wes and me know, and we will add this to the agenda asap. Also, if there are WGs who would like to use larger blocks for dedicated discussion time, this would be a good opportunity as well. Wes has already created a registration link, so please register asap if you plan to attend, so we can the needed data for eligibility and quorums. https://urldefense.us/v3/__https://www.mpi-forum.org/meetings/2024/06/logis… Thanks and my apologies again for the missing reminder – let’s still make the best out of it!

Please feel free to distribute it to those who might be interested. ********************************************************************** EuroMPI is an annual conference with a focus on advancing the ubiquitous Message Passing Interface (MPI) model and specification of parallel programming. It also encompasses extensions and alternative interfaces for high-performance heterogeneous and hybrid systems, benchmarks, tools, parallel I/O, fault tolerance, and parallel applications using MPI and other interfaces. The EuroMPI conference series has been attracting an international audience of leading academic and industrial experts since 1994. EuroMPI/Australia 2024 (25-27 September 2024) will be hosted by the Pawsey Supercomputing Research Centre in Perth, Australia, and will be co-located with the International Workshop on OpenMP - IWOMP 2024 (23-26 September 2024). Having EuroMPI, IWOMP, and the MPI Forum grouped together allows attendees to interact and share ideas and experiences to contribute to the improvement and furthering of message-passing, shared-memory parallelism, and related parallel programming paradigms - and their combined usage. Through the presentation of full papers, short papers, posters, and invited talks, the meeting will provide ample opportunities for attendees to interact and share ideas and experiences to contribute to the improvement and furthering of message-passing and related parallel programming paradigms. We solicit quality submissions of unpublished work that detail innovative, original research and development related to MPI. We invite high-quality, paper submissions on all topics related to message-passing parallel programming with MPI and related or competing models. Topics of interest include, but are not limited to: - Implementation issues and algorithms: Efficient and scalable implementations of message-passing constructs. - Architectures and systems: Towards exascale computing, efficient use of accelerators and other features of modern, large-scale systems, hardware-software interaction. - Programming models and paradigms for large-scale, parallel, distributed memory systems, hierarchical and hybrid models, partitioned global address space (PGAS) models. - Extensions to and shortcomings of MPI, alternative interfaces and solutions. - New, parallel (MPI-)I/O mechanisms optimizations. - Hybrid and heterogeneous programming with MPI and other interfaces. - Message passing interface support for data-intensive parallel applications. - Fault tolerance in message-passing implementations and systems. - MPI parallel programming in clouds and non-dedicated systems. - Applications and performance: Performance evaluation for MPI and MPI-based applications. - Automatic performance tuning of applications and implementations. - Verification of message-passing applications and protocols. - Applications using message passing, in particular in computational science and scientific computing. - Parallel algorithms in the message-passing paradigm. - Interactions between the message-passing library and runtime systems. Papers will be reviewed for quality, originality, clarity, correctness, technical strength, and relevance to the topics of the meeting. Each paper will receive at least three reviews from members of the program committee. Reviews are blind (but not double-blind), the names of the authors will be seen by the program committee. Papers that are not accepted for publication in the proceedings may still be recommended for short presentations or poster presentations. All accepted full papers will appear in the conference proceedings. Additionally, selected short papers can be included in the conference proceedings. All other accepted short papers and posters will be published informally on the website, but are not intended to appear in the proceedings. Even without inclusion in the proceedings, we consider short presentations and posters to be a good way to present early work to the community, which can lead to discussions, constructive feedback, and collaboration opportunities. Among the papers selected for presentation, a few of the best papers will, as has been the tradition for the last couple of years, be selected by the program committee and recommended for publication in a EuroMPI 2023 plus EuroMPI/Australia 2024 Special Issue of a Journal, more details about the journal special issue coming here soon. These papers will go through a separate round of reviews and are intended as extended, more polished versions of the conference versions. ********************************************************************** SUBMISSIONS: Submitted papers should follow LNCS Guidelines https://urldefense.us/v3/__https://www.springer.com/gp/computer-science/lnc… <https://urldefense.us/v3/__https://www.springer.com/gp/computer-science/lnc…> and obey the Authors' Code of Conduct. https://urldefense.us/v3/__https://www.springernature.com/gp/authors/book-a… <https://urldefense.us/v3/__https://www.springernature.com/gp/authors/book-a…> Submitted full papers should be 12-15 pages, and short papers should be 6-11 pages (not all short papers will appear in the proceedings).
