I don't think Martin has started putting together the agenda yet, but we've asked for time for a reading of the error handler issues and a half day time for WG time to discuss catastrophic errors and continue our ULFM/Reinit/etc. discussions.

Catastrophic Errors
by Bland, Wesley 03 Aug '17

03 Aug '17

Hi all, Pavan raised an interesting use case for catastrophic errors just now on the issue page: https://github.com/mpi-forum/mpi-issues/issues/28#issuecomment-319980621 I'm not sure if everyone tracks what's going on there or not, but it would be helpful to have some other feedback on the GitHub issue. For now, I'm going to reopen the issue so we can decide whether we want to move forward. Thanks, Wesley

Rob, Here is the pointer to the dissertation about a production grade memory database using ULFM as a communication substrate that can deal with different types of faults. The approach taken here is to add a layer of resilient collective to supplement the rest of the API, and to facilitate the integration of this code in the rest of the software infrastructure. The result section at the end shown very good results, basically 1/2 the time of the restart approach (even for small problems with 1GB / process).
