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. vega Vega Lew （weijia liu) PH.D Candidate in Chemical Engineering State Key Laboratory of Materials-oriented Chemical Engineering College of Chemistry and Chemical Engineering Nanjing University of Technology, 210009, Nanjing, Jiangsu, China _________________________________________________________________ Explore the seven wonders of the world http://search.msn.com/results.aspx?q=7+wonders+world&mkt=en-US&form=QBRE
