MPI Forum Trac users to be deleted
by Jeff Squyres 30 Nov '09

30 Nov '09

There are a pile of users who were created in the MPI Forum Trac but never activated (meaning the accounts were created, but the user never logged in). If these users still don't login within the next week, we're going to remove them: lums dnagorny mpiforum thakur ecap matthijsvanwaveren ryzevia penoff gingold jmlover jrkingsb chanel570816 hpcbetti ghrisgottbrathtvtech trj_ornl.gov geoffp laipi s-sumi ptero RikiKiki JackyLee blavkmarble jeackariecevy mcnightflash Alex-usda-ru insocuoum YCMichael -- Jeff Squyres jsquyres(a)cisco.com

Hi all, >> Last meeting we were supposed to have the first vote on ticket #171: Ticket 171 has already the first vote. We have to do the second (=final) vote!

Errata: Ticket #171
by Graham, Richard L. 24 Nov '09

24 Nov '09

Last meeting we were supposed to have the first vote on ticket #171: Change MPI_C_BOOL external32 size to 1 byte We did not do this, and there was a suggestion that we make an exception, and have a mail vote by those organizations that were eligible to vote in the last meeting, and were present at that meeting. I propose that we go ahead with this vote on the errata. If people object to this, please let me know by Friday, Dec 4th. If there are no objections, we will follow with a 2 week voting window. Rich

The meeting in Atlanta will go ahead as planned Tuesday ï¿½ Thursday, Jan 19-21. However, logistics will NOT be in place for up to a month. I know I will start getting questions on this soon, so just wanted all to know about this delay in advance. Rich

Re: [Mpi-forum] Final call: user survey
by Richard Treumann 18 Nov '09

Given these 2 statements: I expect to be able to upgrade to an MPI-3 implementation and still be able to run my legacy MPI applications *without recompiling*. I expect to be able to upgrade to an MPI-3 implementation and only need to recompile my legacy MPI applications *with no source code changes*. If I have said "Strongly agree" on the first because I think breaking binary compatibility is intolerable, do I "Strongly disagree" or "Strongly agree" with the second? How much are each of the following sets of MPI functionality used in your MPI applications? should distinguish between multiple compute threads with one thread making MPI calls vs multiple threads expecting good performance from concurrent MPI calls. It would be really good to know how may people would be happy to use MPI_THREAD_FUNNELED with one MPI task per OSI (node) but reluctantly do more complex things because an MPI call on a single thread does not give them full utilization of the network resources.
