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/MPI_plans_10thJuly2008.pdf
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). The direct link is
https://svn.mpi-forum.org/trac/mpi-forum-web/raw-attachment/wiki/PersColl/perscoll_16042008.html
