Errata Vote Announcement
by Marc-André Hermanns 19 Dec '24

19 Dec '24

Dear all, we would like to bring the following issue and PR up for erratum vote in the January meeting. Title: UB for passing uninitialized variables to "significant only at root" arguments Issue: https://github.com/mpi-forum/mpi-issues/issues/854 PR: https://github.com/mpi-forum/mpi-standard/pull/988/files There remain other locations in the standard that use the term 'significant at root' that are not accompanied by the proposed AtU, but it remained unclear in the discussion on how to incorporate the AtU at those places in the text, without changes that may easily go beyond a simple erratum change. Therefore, we decided to go with this minimal change now and revisit this topic again with a broader discussion on how to improve the text without a specific time constraint. Cheers, Marc-Andre -- Dr. rer. nat.

Dear all, after input from Joseph and following discussion in the Tools WG on Monday, I prepared a minimal PR that hopefully reflects the straw poll results obtained after the Forum meeting last week.

Please add no-no votes on my addition of changelog entries. This required adding non-ABI-specific stuff to create the changelog section as well as macros for MPI-5, which I expect to be the version number we use, but of course this can be changed to 4.2 later. https://urldefense.us/v3/__https://github.com/mpi-forum/mpi-standard/pull/9… https://urldefense.us/v3/__https://github.com/mpi-forum/mpi-standard/pull/9… Jeff On Sun, Dec 15, 2024 at 11:07 PM Jeff Hammond <jeff.science(a)gmail.com> wrote: > Two voting announcements for the January meeting: > > https://urldefense.us/v3/__https://github.com/mpi-forum/mpi-standard/pull/9… (ABI without Fortran) > >> https://urldefense.us/v3/__https://github.com/mpi-forum/mpi-standard/pull/9… (ABI with Fortran) > > The Fortran ticket needs a no-no vote on the change to > remove MPI_Op_create_x based on the lack of consensus about this function. > > > https://urldefense.us/v3/__https://github.com/mpi-forum/mpi-standard/pull/9… > > > https://urldefense.us/v3/__https://github.com/mpi-forum/mpi-standard/pull/9… > > > I will propose MPI_Op_create_x for a future release of the standard once > we have strong consensus on the design. > > Jeff > > -- > Jeff Hammond > jeff.science(a)gmail.com > https://urldefense.us/v3/__http://jeffhammond.github.io/__;!!G_uCfscf7eWS!Z… > -- Jeff Hammond jeff.science(a)gmail.com https://urldefense.us/v3/__http://jeffhammond.github.io/__;!!G_uCfscf7eWS!Z…

Hi all, As discussed at the end of the last voting meeting, we will have a non-voting virtual meeting today. Marc-Andre will discuss suggested wording options to fix the issue of undefined behavior for passing uninitialized variables to “significant only at root” arguments. The meeting information is on the webpage (note, pick the zoom link at the bottom of the page, which is for the non-voting meetings). 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 You never fail until you stop trying.

Hello, I’d like to bring forward the clarification text for MPI memory kind’s default value during the January 2025 voting meeting for an erratum vote: https://urldefense.us/v3/__https://github.com/mpi-forum/mpi-standard/pull/9… Thank you, Rohit From: mpi-forum <mpi-forum-bounces(a)lists.mpi-forum.org> on behalf of Wes Bland via mpi-forum <mpi-forum(a)lists.mpi-forum.org> Date: Saturday, December 14, 2024 at 2:42 AM To: MPI Forum <mpi-forum(a)lists.mpi-forum.org> Subject: [Mpi-forum] January 2025 Meeting Registration and Call for Topics External email: Use caution opening links or attachments Hi all, TL;DR 1. New meeting coming up on Jan 8. Announce readings and votes 2. Register for meeting 3. Indicate attendance for March meeting Despite just having finished a meeting this week, we have another meeting coming up soon as we move ZjQcmQRYFpfptBannerStart This Message Is From an External Sender This message came from outside your organization. ZjQcmQRYFpfptBannerEnd Hi all, TL;DR 1. New meeting coming up on Jan 8. Announce readings and votes 2. Register for meeting 3. Indicate attendance for March meeting Despite just having finished a meeting this week, we have another meeting coming up soon as we move toward the next version of the MPI Standard. The next meeting will be a virtual voting meeting on January 8th, 2025. This will be the last opportunity for 2nd votes and errata readings and votes for the next version of the MPI Standard. If you have anything you want to be discussed or voted on, it must be announced on the mailing list before December 25th. Obviously, many people will not be working that day, so it would be good to announce as early as possible. As a reminder, I do not carry over first votes from previous meetings so all readings need to be announced. Please let Martin and I know about any other discussions that you'd like to have at this meeting. Please also go ahead and register for the meeting here: https://urldefense.us/v3/__https://forms.gle/A8FHm7BVAZUeFfLw6__;!!G_uCfscf… <https://urldefense.us/v3/__https://forms.gle/A8FHm7BVAZUeFfLw6__;!!G_uCfscf…> Lastly, if you haven't already indicated your availability for our in-person Release Candidate Meeting in Stuttgart, Germany in March, please do so here: https://urldefense.us/v3/__https://forms.gle/aFyvvk7j8EurfBoX7__;!!G_uCfscf… <https://urldefense.us/v3/__https://forms.gle/aFyvvk7j8EurfBoX7__;!!G_uCfscf…> I'm excited that we already have 15 people planning to come in-person. I hope many more will be able to join us in particular for this meeting as it makes the final process of finishing an MPI Standard version easier. Thanks, Wes

Two voting announcements for the January meeting: https://urldefense.us/v3/__https://github.com/mpi-forum/mpi-standard/pull/9… (ABI without Fortran) > https://urldefense.us/v3/__https://github.com/mpi-forum/mpi-standard/pull/9… (ABI with Fortran) The Fortran ticket needs a no-no vote on the change to remove MPI_Op_create_x based on the lack of consensus about this function. https://urldefense.us/v3/__https://github.com/mpi-forum/mpi-standard/pull/9… https://urldefense.us/v3/__https://github.com/mpi-forum/mpi-standard/pull/9… I will propose MPI_Op_create_x for a future release of the standard once we have strong consensus on the design.
