It has been on my to-do list for a while to start a FAQ listing of the various resilience/FT related activities in and around Open MPI. This would provide a starting location for users and new developers could go to for an overview of each of the features, and how to activate/use the feature.
I'll try to bump that up the priority list and post a message once it is ready. Probably a month or so off since I need to collect some information from various developers. -- Josh On Sun, Jun 26, 2011 at 6:01 PM, Ralph Castain <r...@open-mpi.org> wrote: > I think we're some ways away from declaring a "resilient ORTE".
