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.

Best,

Jeff

Jeff -

Thanks for the reminder. We had a meeting two weeks ago, the notes are on the web page:

https://svn.mpi-forum.org/trac/mpi-forum-web/wiki/PtpWikiPage

There's another meeting at 11:00am Central today. Someone scheduled a meeting I can't reschedule for 10:30 - 11:00 this morning, so I'm going to be 5 minutes late. Call in information is on the Wiki page.

Hi all -

At the Forum today, progress was made at re-instituting the point-to-point working group. We'll initially be focusing on the point-to-point reduce and the unknown message size receive problem. If you're interested in joining in, please join the mailing list:
