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. Do we want to mention somewhere in the document, that different objects might have different default error handlers attached? You have a distinction between COMM_WORLD and COMM_SELF -- which is good, but maybe we should explicitly mention other objects as well... Thanks Edgar Supalov, Alexander wrote:
Dear Rich,
Thanks. We had a scheduled site maintenance and my phone connection was terminated for some reason. Sorry for that.
Sure, I can take on fleshing out the rest of the fault handling proposal. I invite everybody to contribute to the respective Wiki page in the meantime (see http://svn.mpi-forum.org/trac/mpi-forum-web/wiki/Fault%20Handling), and/or send comments to me or this list.
Best regards.
Alexander

Here is a summary of the action items from today's call: - The consumer/producer scenario is ready for discussion before the full forum, once we have nailed down the approach to error handling within MPI. The plan is for Edgar to bring this to the full forum for discussion at the April meeting. - The approach to error handling is almost ready to bring to the full forum. Several items came up in today's call (async notification and handler stacking) that still need to be fleshed out and fully defined. Alexander, since you were kicked off the call - would you be willing to coordinate getting this ready for discussion in the full forum setting at the April meeting ? We should discuss this again an the call in 2 weeks (4/11/2008) and go over the remaining items. - Josh will work with ? to get the proposal for non-blocking dynamic process creation ready to go. We should aim to continue discussions on this next time, but this may not be ready by the April meeting. If the forum is amenable to this proposal, it should be integrated with the rest of dynamic process control chapter.
Also, time permitting we will discuss the data piggy backing proposal on the next call.
What did I forget? Rich
