Wifi credentials for MPI Forum meeting @Cisco next week
by Jeff Squyres (jsquyres) 30 Nov '17

30 Nov '17

For those of you registered for the Forum meeting next week, you probably got a few emails from me/Cisco with wifi credentials next week. Short version: - they're all valid - looks like the Cisco guest badging system now automatically *also* issues wifi credentials (previously, I had to file for guest wifi credentials separately) So -- feel free to bring additional wifi devices to the meeting next week. :-) -- Jeff Squyres jsquyres(a)cisco.com

Hi Rusty, Thanks for the feedback and the encouragement - the thanks also have to go to Wesley Bland and Jeff Squyres, though, who in their role as forum secretaries helped write the text and/or have been good sounding boards for these issues!

Hi all, Based on the discussions last time on improving the MPI standardization process, Wesley and I have been working on updates to the MPI forum procedures. There are two separate proposals, one on rules for companion documents and one on including virtual meetings. Both will be read and discussed at the upcoming forum meeting and we intend to put them up for a vote if we successfully discuss them. Both proposals are available from the MPI meeting agenda page: http://mpi-forum.org/docs/other/procedures-22.pdf http://mpi-forum.org/docs/other/procedures-30.pdf Thanks! Martin

Persistent Collective Communication Reading Request for February 2018 Meeting
by Anthony Skjellum 17 Nov '17

17 Nov '17

Please schedule a reading for issue #25 (pull request #29). https://github.com/mpi-forum/mpi-issues/issues/25 <https://github.com/mpi-forum/mpi-issues/issues/25> Adding Persistent Collective Communication · Issue #25 ... <https://github.com/mpi-forum/mpi-issues/issues/25> github.com This ticket proposes non-blocking persistent collective operations be added to the standard. The associated PR is at: mpi-forum/mpi-standard#29 Useful links: https://github.com/mpi-forum/mpi-issues/issues/25 https://github.com/mpi-forum/mpi-standard/pull/29 https://github.com/mpi-forum/mpi-standard/files/1483740/mpi32-report.pdf Summary of changes: Point to point chapter ----------------------------- 3 .9 Clarification that persistent collective requests cannot be freed while active. Collective Communication Chapter ---------------------------------------------- 5.13 Added Persistent collective communication functions 5.13.1 -- Added section to discuss Info Keys related to Persistent Collectibrs 5.13.2-5.13.13 -- Added one-to-one a persistent collective for every corresponding nonblocking collective Process Topologies chapter ------------------------------------ Added Section 7.8 -- Persistent collective communication for communication on process topologies; added one-to-one a function for every nonblocking topological collective operation As noted previously, we have a working functional implementation (libPNBC) as well. This is the implementation that matches the proposal. Please note that this will be a full reading. We went over the material in the September meeting, but determined we needed to do a new reading in December after making clarifications on several points raised in Chicago. In particular, we explain the semantics of MPI_Request_free for collective requests. And, we explain the life-cycle of persistent collectives requests as being valid for zero-or-more uses after their respective _Init.
