[mpich-discuss] Is there a way to set timeout to mpi process launch?

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?
