4) Updates on MPI Plans (I have a slightly different proposal/implementation than Christian for the same thing) I just added my proposal to the wiki in case anybody wants to take a look at it before or during the telecon: https://svn.mpi-forum.org/trac/mpi-forum-web/wiki/MPIplans (scroll down to the bottom). Thanks Torsten!

And for completeness, I attached my interface proposal for "MPI plans" to the same wiki page (very bottom). Alternatively the direct link is: https://svn.mpi-forum.org/trac/mpi-forum-web/raw-attachment/wiki/MPIplans/MP... This description has already been revised a couple of times, and is since 10th of July in a quite stable and hopefully complete state. A second implementation (independent of Torsten's reference-implementation) for NEC's proprietary MPI has been completed and is currently evaluated/tuned in application contexts. The difference to Torsten's proposal is quite small and is mainly based on the question if we should give some memory management things to the programmer (because she might know already how large the plan will become) or hide all these aspects. I'm locking forward to discuss the advantages/disadvantages of both ways with the audience. Best regards, Christian PS: Since April there is also a first draft for persistent collectives in the wiki (see appropriate section).
