[Mpi3-ft] MPI Process Management Proposal - Updated
by Josh Hursey 11 Apr '08

11 Apr '08

I just updated the Process Management proposal in the wiki: http://svn.mpi-forum.org/trac/mpi-forum-web/wiki/Async-proc-mgmt This contains discussion of the non-blocking process management interfaces. It also moved the discussion of connect/accept extensions from the FT Mgr/worker proposal to this one for consolidation purposes. I put a note in the FT Mgr/Worker proposal indicating this transition, but did not remove any of the original text from it so we can have it as a reference. This should be regarded as a rough draft still as I made no actual attempt at writing precise standardize language, but opted for a more casual presentation so we can more freely discuss the high level merits of the proposal. Sorry for the delay on this. I was hoping to finish it earlier to allow more time for review before the teleconf. Cheers, Josh

[Mpi3-ft] fault handling proposal updated in Wiki

Hi everybody, Thanks a lot for your comments on the fault = error proposal.

Re: [Mpi3-ft] Summary of today's call

Dear Edgar, Thank you. I've not thought about error classes for fault handling yet, but most likely they will have to be added. The files, etc. are mentioned in the second half of the proposal (I hope). In any case, the intention has always been to use any of the objects that can carry error handlers for fault tolerance as well. Best regards.

Do we want to address that, i.e. does the concept make sense and we suggest to keep it, do we modify the concept since the original idea and its benefits are not entirely clear or do we want to get rid of error classes? second, if I remember right, MPI_FILE_NULL has a different default error handler than MPI_COMM_WORLD.
