Fab: Hmm. I don't know if is a ticket 0 change (probably not) but it definitely is an errata that we should fix before we relaese MPI-3.0. Can you write up a ticket? I'm happy to look over the text. I hope this can get on the March agenda since it should...

MPI_WAIT/MPI_TEST and generalized, I/O, and NBC requests
by Fab Tillier 10 Feb '12

10 Feb '12

Hi Folks, Looking at the text for MPI_WAIT (page 54, line 15) and MPI_TEST (page 55, line 7), it seems to imply that the request handle is only set to MPI_REQUEST_NULL for non-blocking send and receive requests. Are generalized, I/O, and NBC requests not completed the same way? Are users required to free such requests explicitly after they complete using MPI_REQUEST_FREE? I would have expected that all request handles except those to persistent requests are set to MPI_REQUEST_NULL, and persistent request just rather marked inactive. If that is indeed the intent, shouldn't we update the text to reflect this? Is this a ticket-0 level change? Thanks, -Fab

Re: [Mpi-forum] Better Use of Time Monday Afternoon

This is a fair suggestion - actually Josh and I talked about this before this was sent out. From what I hear now, seems like the discussions with the RMA group and the I/O folks are going fine, and seems like the open issues with the fault-stabalization proposal should be ironed out very soon. The other 2 proposals will get a first discussion in the WG this week, and then we should have an idea where things stand, and can make an informed decision.

Better Use of Time Monday Afternoon
by Bronis R. de Supinski 07 Feb '12

07 Feb '12

Rich: I have been lurking on the FT mailing list and I have observed that we are far from agreement on the form of interface on which we should standardize, let alone how to spell it. While I appreciate the time that you and Josh have put into the RTS proposal, it is clear that we should not adopt it at this time. As a result, I respectfully comment that a reading of the RTS ticket on Monday afternoon is not a productive use of the Forum's time. I think it would be much better to review the new proposals (and perhaps changes to the RTS proposal). Further, since we are already running long for this March meeting, we should reduce the session to a more reasonable two or three hours and not five. I relaize that you are free to insist on reading the ticket. However, I do not see the benefit of ramming through the reading only to have it almost certainly be defeated when it comes time to vote.

If you need help installing MPICH2 on Windows, try mpich-discuss(a)mcs.anl.gov. This email list is for topics related to the MPI standard.

Re: [Mpi-forum] March MPI Forum meeting

Upon further peer review, ticket #291 has been withdrawn. Comments regarding the discussion have been appended to the ticket for those interested. So there is no need to add it to the agenda for March.

Jeff, I plan to look at the agenda again over the weekend, and will see what things look like. The agenda is more than packed, so if there is time we will keep 159, otherwise we will defer to later.
