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.
