Pythonization effort
by Jeff Squyres (jsquyres) 26 Nov '19

26 Nov '19

This is not going to be a formal reading for the December meeting (because we're not expected to be done by then), but we will present the bindings Pythonization effort in December. The end effect will be a "largely ticket 0" result on the MPI-4 document, but since this touches nearly every chapter in the spec, it's important to get this in front of the Forum, and possibly even vote on it using the errata process. I've created an issue with details on the proposal, details on the process, and links to the Virtual Meeting slides and the current status of the rendered PDF document here: https://github.com/mpi-forum/mpi-issues/issues/158 -- Jeff Squyres jsquyres(a)cisco.com

Voting on Safe String Handling tickets for MPI_Info
by Grant, Ryan Eric (-EXP) 25 Nov '19

25 Nov '19

Hello Everyone, I’d like to announce the following tickets for voting at the MPI Forum in Albuquerque. They are separate tickets for the solutions that were discussed for safe string handling with MPI for Info strings for the readings in Zurich and Chicago. Minor changes (if any) on the tickets since their last readings are included in a single commit, linked to at the bottom of each ticket. It is intended that Ticket #146 will be voted on first and if it passes, ticket #133 will be withdrawn (not voted on). There are minimal clarifying changes to the text that do not impact the behavior of the proposals in any way. These will require a no-no vote. Ticket #146: https://github.com/mpi-forum/mpi-issues/issues/146 This solution uses a single function MPI_Info_get_string to both provide required buffer lengths and the value string itself. Ticket #133: https://github.com/mpi-forum/mpi-issues/issues/133 This solution proposes two new functions for safely handling string MPI_Info_get_string and MPI_Info_get_buflen Ticket #147: Deprecates the existing functions of MPI_Info_get and MPI_Info_get_valuelen that were unsafe in C Best Regards, Ryan ================================ Ryan E. Grant Principal Member of Technical Staff Center for Computing Research Scalable Systems Software Department Sandia National Laboratories Albuquerque NM, USA 505-844-1252 regrant(a)sandia.gov<mailto:[email protected]>
