I am leaving Tuesday night after the Forum for Annapolis. Jim is going to OpenSHMEM but not the Forum last time I heard. I believe Brian is heads-down on AWS now and won't be involved in the Forum any more, but I could be wrong.

Hi Bill, I updated the wiki page, with some more tickets. Note that some of the open tickets that I added were capturing an idea or a question that came up in discussion, so they need not all receive discussion at the upcoming meeting. Unfortunately, I won't be able to attend this meeting. Depending on the timing, if there is a bridge set up, I may be able to dial in. Best, ~Jim.

Bill, Pavan, Rajeev, Brian, Dave and Jeff, Bill, thank you for the ticket. Pavan, thank you for supporting it in the March meeting (Rajeev will not be there). Is there a RMA WG Meeting at the March Forum Meeting? Will you do an MPI-3.0 errata plenary reading or will you put it into the errata by WG dicision, because it is only an example? In both cases #413 should be latest tomorrow on the agenda. Because it is one block of text at one precise location, the ticket format may be enough formalism, i.e., no extra pdf.

MPI Aint arithmetic formal proposal
by Jim Dinan 11 Feb '14

11 Feb '14

Hi All, Apologies that I did not send this to the RMA list the first time around: I have prepared a formal proposal for tickets #349 (MPI_Aint_add), #402 (RMA example updates), and #404 (MPI_Aint_diff) and attached it to #349: https://svn.mpi-forum.org/trac/mpi-forum-web/attachment/ticket/349/review-3… Please help me to review this document before the window closes on readings at the March meeting. Updates to the examples don't put change markers in the margins, so please search for the ticket numbers to locate all of the changes. I have moved the proposal to SVN under trunk/working-groups/mpi31/ticket-349/. Thanks! ~Jim.

Note that #362 is included in the proposal (sorry I goofed on the upload and forgot to click "replace existing file" *facepalm*) for reference and reassurance only. Ticket #326 has already been passed as an erratum. ~Jim. On Tue, Feb 11, 2014 at 11:55 AM, Jeff Hammond <jeff.science(a)gmail.com>wrote: > I assume this is trivial so I can do it.
