You can try setting MPIEXEC_TIMEOUT=<timeout value in seconds> to force the job to abort after running for the specified period. This is for the whole execution though, not just for the process launching step. Halim www.mcs.anl.gov/~aamer On 10/26/16 6:30 PM, Pranav Ladkat wrote:

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
