Hi, When I run mpi program on multiple hosts, if executable fails to start on any of the host (due to missing library etc. type of reasons), other hosts just keep waiting for the process to come up. The program just hangs forever. Is there any way to set a timeout in such cases such that MPI should abort if not all processes were launched in a given timeout period? Thanks, Pranav _______________________________________________ discuss mailing list [email protected] To manage subscription options or unsubscribe: https://lists.mpich.org/mailman/listinfo/discuss
