Errata for reading
by Jeff Squyres (jsquyres) 31 Jul '20

31 Jul '20

The Fortran/language bindings working group would like to announce the following issue and associated pull requests for reading at the next Voting Meeting: * "Fortran errata: Clarify where TYPE(MPI_Status) type must be defined": https://github.com/mpi-forum/mpi-issues/issues/298 * MPI-3.x errata PR: https://github.com/mpi-forum/mpi-standard/pull/262 * MPI-4.0 errata PR: https://github.com/mpi-forum/mpi-standard/pull/255 It is the same issue for both PRs, hence there's only one issue. However, the PRs are quite different between the mpi-3.x and mpi-4.x branches because of the Pythonization of the MPI bindings on the mpi-4.x branch. Hence, there's two different PRs. The rendered text changes between the two PRs are (nearly) identical: the only difference is the annotation of the Fortran bindings in section 18.2.5 (the difference is due to Pythonization). The issue has links to the PRs and associated PDFs for review. -- Jeff Squyres jsquyres(a)cisco.com

EuroMPI/USA 2020: Call for Research Poster (Submissions due Jul 25, 2020)
by Marc-André Hermanns 20 Jul '20

20 Jul '20

Subject: EuroMPI/USA 2020: Call For Research Posters **** EuroMPI/USA 2020 **** **** Austin, TX USA **** **** Sep 21-24, 2020 **** Research Poster Submissions due Jul 25, 2020 (AOE) EuroMPI/USA 2020 will continue to increase its focus outside MPI, to include extensions or alternative interfaces for high-performance homogeneous/heterogeneous/hybrid systems, benchmarks, tools, parallel I/O, fault tolerance, and parallel applications using MPI and other interfaces. Through the presentation of contributed 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. The poster session at the EuroMPI 2020 conference is an excellent opportunity to engage with the community and propose and discuss new ideas and latest results not yet ready to be full papers. We are soliciting poster submissions for EuroMPI 2020 that show-case work on the Message Passing Interface (MPI) or work that is related to message-passing parallel computing. We invite submissions from users of MPI, developers of MPI, and researchers in the broader field of message-passing parallel computing. We particularly encourage graduate students to publicize their ongoing work. Topics of interest include, but are not limited to: Implementation Issues * Implementation improvements towards exascale computing, such as many-core, GPGPU, and heterogeneous architectures. * Performance bugs in MPI implementations. * Interaction between message-passing software and new high-performance hardware architectures. * New MPI-IO mechanisms and I/O stack optimizations. Programming Models * API limitations of MPI; extensions to MPI. * Hybrid and heterogeneous programming; combining MPI with other interfaces. * MPI support for data-intensive parallel applications. * Fault tolerance in message-passing implementations and systems. * New programming paradigms implemented over MPI, like hierarchical programming and global address spaces. * MPI parallel programming in clouds. Applications and Performance * Performance evaluation for MPI or MPI-based applications on HPC machines or using cloud resources. * Automatic performance tuning of MPI applications and implementations. * Verification of message-passing applications and protocols. * Applications using message passing, for example, in computational science and scientific computing. * New parallel algorithms expressed in the message-passing paradigm. Posters will be reviewed for quality, originality, clarity, correctness, technical strength, and relevance to the topics of the meeting. Each poster will receive at least 3 reviews from members of the poster committee. Reviews are blind (but not double-blind), the names of the authors will be seen by the poster committee. Important Dates: - Submission Deadline: Jul 25, 2020 (AOE) - Notification of Acceptance: Aug 15, 2020 Submission Guidelines: All posters need to be submitted through EasyChair: https://www.easychair.org/my/login_author?conference=244017 All poster submissions must include: * A title and a short abstract (175 word maximum). * An extended abstract (3 pages maximum, including figures and references, and formatted according to the “sigconf” style in the ACM 2017 Template (http://www.acm.org/publications/proceedings-template) * A poster draft. Note that complete results are not necessary. It is acceptable to have placeholders for last- minute results. * Poster format should be A0 page size (either portrait or landscape). See the attached size guide instructions for more details. The abstracts and posters will NOT be published in the conference proceedings. Due to the Covid-19 situation, the posters selected this year will have an entirely online presentation, divided in two parts: a promotional video and an online presentation. The authors of accepted posters will need to create a short 5 minute promotional video discussing the poster, that will be posted on the EuroMPI'20 website 2 weeks prior to the event. During the EuroMPI'20 event posters will be presented in an online session as part of the conference program, followed by discussions. Poster Track Chairs: - George Bosilca, The University of Tennessee, Knoxville, USA - Marc-Andre Hermanns, RWTH Aachen University, Germany Poster Committee: - Anja Gerbes, Goethe Universität Frankfurt, Germany - Claudia Blaas-Schenner, TU Wien, Austria - Julien Jaeger, CEA, France - Servio Rivas-Gomez, EPFL, Switzerland - Radita Liem, RWTH Aachen University, Germany - Emmanuel Jeannot, INRIA, France - Nuria Losada, The University of Tennessee, Knoxville, USA -- Dr. rer. nat.

by Mohror, Kathryn 20 Jul '20

20 Jul '20

Hi all, This is a friendly reminder that the PMIx Q3 ASC Meeting will be held this Wednesday July 22 (see below for details). Thanks, Kathryn From: pmix-forum(a)googlegroups.com<mailto:[email protected]> <pmix-forum(a)googlegroups.com<mailto:[email protected]>> On Behalf Of Josh Hursey Sent: Monday, June 29, 2020 2:12 PM To: pmix-forum <pmix-forum(a)googlegroups.com<mailto:[email protected]>> Subject: [pmix-forum] Q3 2020 PMIx Standard Quarterly Administrative Steering Committee (ASC) Meeting Hello everyone, The PMIx community is pleased to announce the third-quarter meeting of the Administrative Steering Committee (ASC) of the PMIx standardization body for 2020. The objective of the PMIx standard is to provide an implementation-independent specification to facilitate interaction between applications, tools, and middleware and system runtime environments. The interface focuses on supporting application launch and wire-up; supporting tools that wish to inspect, steer, and/or debug parallel applications; providing interfaces to manage dynamic workload applications, to support fault tolerance and cross-library coordination; and facilitate communication across container boundaries. The PMIx standard is governed by the ASC comprised of representatives from a wide range of research, academic, and industrial organizations. The ASC plays a critical role in shaping the evolution of this critical system interface. The goal of this meeting is to read, discuss, and vote on modifications to the PMIx standard, discuss potential modifications or new ideas for the standard, welcome formal participation in the governance body from new, interested groups, and learn of community progress with respect to PMIx. As such we are calling for broad participation from the parallel and distributed computing community to participate in this meeting. Meeting information: * Date: July 22, 2020 * Time: 11 am - 5 pm US Central Time * Location: Virtual (online) Meeting (see agenda link for details) * Meeting Link: https://github.com/pmix/pmix-standard/wiki/ASC-Q3-2020-Meeting For more information about the PMIx standardization body and its activities please join the mailing list [1], check out the activity on the GitHub repository [2], and/or review the website [3]. Note that we will still hold our monthly teleconference on July 10. Watch the email list for details.

Upcoming MPI Meetings and Topics
by Martin Schulz 12 Jul '20

12 Jul '20

Hi all, Thanks everyone again for a highly productive meeting the other week. We got a lot of issues completed and we seem to be on track with MPI 4.0, which is great. As discussed, we will have an additional virtual voting meeting on August 17-19 and I started to compile the agenda. Priority goes to the issues needed for MPI 4.0, but we will probably have time to also start talking about MPI 4.1/5.0 issues. If you and/or your work WG would like to bring something forward for the agenda, please let Wesley and me know. Leading up to the meeting, we have slots for only 3 (!) virtual meetings in our usual Wednesday slot before the ballot deadline on August 3rd (please keep this in mind for announcing any readings to ballots). These dates are: - July 15th - July 22nd - July 29th The first one is reserved for the errata re-readings from the tools WG, but we may also have time for other topics, the other slots are still open. If a WG would like to discuss an issue, please let us know. We also decided to turn the September and December meetings virtual - those will run on a similar schedule as the one we just had on the original dates. We will post the details as we get closer. For the following year, we are looking at the following dates: - Spring: February 22-25 - Summer: June 7-10 Please double check the dates - unless we hear objections, we will fix those dates in the next week. We will leave open whether those meetings will be virtual or physical (or hybrid) until we can judge the situation better. As for the September 2021 meeting, the plan is to again coordinate with EuroMPI (as well as iWomp) and hence we will wait on that organization before making further plans. Thanks!
