there's plenty of good places in that area. the place we want drinking last time has reasonable food as far as i know. can you share details about your optimized implementation in written form? if you're implementation is MPICH2-derived then i'd prefer to read the code. jeff On Thu, Jul 12, 2012 at 1:59 PM, Torsten Hoefler <htor(a)illinois.edu> wrote: > Dear RMA Group members, > > We found some small issues with #284 and would like to discuss them in > the RMA working group before bringing them forward to the Forum. > > I can also speak about some early experiences with implementing (an > optimized) version of MPI-3 RMA.

I unfortunately have a 9:00 flight out of ORD, so I won't be able to stay very long if we meet. Do we really want to focus on things that are post MPI-3 at this meeting (keeping in mind, we can't add info arguments to MPI-3 at this point)?

Dear RMA Group members, We found some small issues with #284 and would like to discuss them in the RMA working group before bringing them forward to the Forum. I can also speak about some early experiences with implementing (an optimized) version of MPI-3 RMA. I think we want to add some info arguments to improve performance of some cases. I propose to have a quick meeting over dinner on Monday. This gives us enough time to present back to the Forum. Given that we probably finish earlier on Monday and time constraints of some people, I'd propose to meet around 6:30. Does somebody know a good place?

Ticket #283 is now also committed (r1244). Please review it or include it in your chapter committee review! I put a copy of the document for your convenience at http://www.unixer.de/sec/mpi-report-r1244.pdf .

[This message got stuck in mailman because the chapter committee is too large (max recipients exceeded :-) -- here is a copy for the working group -- Thanks, Torsten] Dear One Sided Chapter Committee and Working Group, Nearly all commits to the One Sided chapter for MPI-3.0 should be done by now (most of them since quite a while). Ticket #283 is unclear, so I didn't commit anything yet. Jim, can you elaborate? Please review the correct implementation of the following tickets *and* sign off *at each ticket* that you reviewed it before the next Forum (in two weeks): #140, #270, #284, #298, #308, #309 Everybody is welcome to review, there can never be enough eyes checking the implementation. You can either pull a copy from subversion or use a build of r1243 that I put at: http://www.unixer.de/sec/mpi-report-r1243.pdf . Please let me know if you have any questions!

Dear One Sided Chapter Committee and Working Group, Nearly all commits to the One Sided chapter for MPI-3.0 should be done by now (most of them since quite a while). Ticket #283 is unclear, so I didn't commit anything yet. Jim, can you elaborate?
