Does the cluster your using use a batch system? Like SLURM, PBS or
other?
If so many have native ways to launch jobs that OMPI can use. SO
that when the job is killed all the children are also.

Dear all,
I have enjoyed the openmpi a couple of days. With the help of
openmpi I could run ESPRESSO efficiently.
I started the mpi-job by the openmpi command like this,
" nohup mpirun -hostfile ~/hostfile -np 64 pw.x < input > output &".
When I want to stop the job before it finished, I find it not easy
to stop all the process manually. When I killed the process
in one node of the cluster, the processes in other nodes were still
running. So I must ssh to every node, find the
process id and kill the process. If there are 100 processors or
more for one mpi job, the situation even worse.
Is there a command for openmpi to force all the process to stop in
the cluster or a list of nodes to stop.
