For some strange reason, I am now locked out of https://svn.mpi-forum.org/trac/ and thus cannot add my material to the ticket. I am trying to reset my password but so far it is not working. In the event that I can contribute to the ticket at some point in the near future, I will.

This overlaps with an Argonne meeting I have to attend that has been a moving target on my calendar until recently. I'll try to to provide detailed material but it possible that I will not be available to discuss it for the entire call.

Meeting notes from this week
by Brian W. Barrett 07 Feb '14

07 Feb '14

Hi all - First, a reminder that as of today, my bwbarre(a)sandia.gov e-mail address will not work. So you can find me at brbarret(a)open-mpi.org. I posted the meeting notes on the wiki: https://svn.mpi-forum.org/trac/mpi-forum-web/wiki/PtpWikiPage/notes-2014-02… For some reason, I forgot to write down who was on the call. So if you were on the call and I forgot to add your name, please edit the wiki or let me know. With all the craziness of switching jobs, my memory is pretty bad this week. Brian

Hi Jeff, Is there any particular reason you want the accumulate op to be specified on the Recv side, vs. the send side? I ask because in RMA we have the accumulate specified on the origin. Typically, most networks expose APIs for atomic ops on the origin side as well. i.e. why not Send_accumulate and Recv.

I attached everything I have in non-mental form for recv_reduce, which is not a huge amount. The first 23 lines of the C file attached are most useful of what I've attached. Dave and Jim have already pointed out that my use of generalized requests is wrong w.r.t. MPI and instead requires the MPICH extension. That shouldn't really matter since I am providing the implementation on top of MPICH only as a reference point for implementers to evaluate the feasibility. When I mention the optimized implementation over PAMI, it might be useful to reference https://bgq1.epfl.ch/navigator/resources/doc/pami/pami_8h_source.html, particularly functions associated with pami_data_function. I don't have a full implementation over PAMI but I can describe the performance of one-sided streaming accumulate, which is how I will implement this if necessary.
