You can join mpi3-ft at http://lists.mpi-forum.org/mailman/listinfo.cgi/mpi3-ft, there is also an archive http://lists.mpi-forum.org/mpi3-ft/ which covers fault tolerance. I was pointed to it here http://www.open-mpi.org/community/lists/users/2011/01/15440.php -- Reuti > On Sep 12, 2011, at 5:52 PM, Rob Stewart wrote: > >> Hi, >> >> I have implemented a simple fault tolerant ping pong C program with MPI, >> here: http://pastebin.com/7mtmQH2q >> >> MPICH2 offers a parameter with mpiexec: >> $ mpiexec -disable-auto-cleanup >> >> .. as described here: http://trac.mcs.anl.gov/projects/mpich2/ticket/1421 >> >> It is fault tolerant in the respect that, when I ssh to one of the nodes in >> the hosts file, and kill the relevant process, the MPI job is not >> terminated.
