You may also want to check with the admin. I know on the system I use, he will prevent you from using many nodes until you demonstrate you know what you are doing. -Original Message- From: users-boun...@open-mpi.org [mailto:users-boun...@open-mpi.org] On Behalf Of Jeff Squyres Sent: Wedn

Can you mpirun non-MPI applications, like "hostname"? I frequently run this as a first step to debugging a wonky install. For example: shell$ hostname barney shell$ mpirun hostname barney shell$ cat hosts barney rubble shell$ mpirun --hostfile hosts hostname barney rubble shell$ On Mar 24, 20

[OMPI users] Non-root install; hang there running on multiple nodes

2010-03-24 Thread haoanyi
Hi, I installed OpenMPI1.4.1 as a non-root user on a cluster. It is totally OK when I run with mpirun or mpiexec on one single node for many processes. However, when I lauch many processes on multiple nodes, I can observe jobs are distributed to those nodes (by using "top"), but all the jobs j

[OMPI users] Meaning and the significance of MCA parameter "opal_cr_use_thread"

2010-03-24 Thread ananda.mudar
The description for MCA parameter "opal_cr_use_thread" is very short at URL: http://osl.iu.edu/research/ft/ompi-cr/api.php Can someone explain the usefulness of enabling this parameter vs disabling it? In other words, what are pros/cons of disabling it? I found that this gets enabled automa
