[mpich-discuss] Fault tolerance of an MPI cluster after one node dies

[YANG Fan]

Hi,

Is it possible for an MPI distributed cluster to continue working if one
node dies? I'm not sure if MPICH provides such functionality.

It seems that MPI_Comm_create requires that all processes in the superset
communicators to be alive; while the errhandler with --disable-auto-cleanup
also does not avoid such issue, as one process cannot call MPI_Finalize().

Thanks in advance!

Best Regards,
Fan
