Hi All, We (Jim and I) have made some progress on the communicator assertions effort! The new ticket 476 (see below) has a new version of the MPI Standard with changes designed to * oblige the user to comply with any INFO keys applied to any MPI object or operation - turning all hints into assertions/promises * prevent the propagation of INFO keys during MPI_COMM_DUP and MPI_COMM_IDUP operations - to protect legacy libraries from have their allowed behaviour being restricted by non-library code We intend to read this at the face-to-face meeting in June. Please review the marked-up changes in the document. Any comments, suggestions, word-smithing can be sent by email. Jim has offered to run the teleconference meeting on Monday 11th May at 11am CDT so that the WG can review and approve this text before the formal reading notice deadline. Cheers, Dan. -------- Forwarded Message -------- Subject: Re: [MPI Forum] #476: Allow Application Behavior Hints in Info Keys Date: Tue, 05 May 2015 14:17:55 -0000 From: MPI Forum <[email protected]> To: undisclosed-recipients:; #476: Allow Application Behavior Hints in Info Keys -------------------------------------+------------------------------------- Reporter: jdinan | Owner: jdinan Type: Text (only) changes | Status: new Priority: Not ready / author | Milestone: 2015/06/01 rework | Chicago, USA Version: MPI 4.0 | Resolution: Keywords: | Implementation status: Unnecessary -------------------------------------+------------------------------------- Changes (by jdinan): * cc: dholmes (added) Old description: New description: See attached proposal. -- -- Ticket URL: <https://svn.mpi-forum.org/trac/mpi-forum-web/ticket/476#comment:1> MPI Forum <https://svn.mpi-forum.org/> MPI Forum -- Dan Holmes Applications Consultant in HPC Research EPCC, The University of Edinburgh James Clerk Maxwell Building The Kings Buildings Peter Guthrie Tait Road Edinburgh EH9 3FD T: +44(0)131 651 3465 E: [email protected] *Please consider the environment before printing this email.* The University of Edinburgh is a charitable body, registered in Scotland, with registration number SC005336.
