Hi, I know that I have to include some information to get the right answer. But, I have one simple question which does not need that information.
1. I could not find any document except FAQ and mailing list for Open MPI. Is there any user manual or something like that? Or, the LAM MPI's manual can be used instead? 2. Another question is about installation. If I want to use rsh/ssh for Open MPI, do I have to install Open MPI on all master and slave nodes? Or, should I use something like NSF file system so that even though I installed Open MPI on only master node, all the other salve nodes could see Open MPI installation in the master node? The error I have is from I wanted to run a program on two slave nodes but shell complained that there is no orted. It is true that there is no installation of Open MPI on each slave node. Thank you, Sang Chul P.S. The Errors when I ran the command line % mpirun --hostfile hostfile -np 2 hello ============================================= bash: line 1: orted: command not found [node00:04841] ERROR: A daemon on node node02 failed to start as expected.
