Hi, When I run any parallel job I get the answer just from the submitting node even when I tried to benchmark the cluster using LINPACK but it look like the job just working on the submitting node is there a way to make openMPI send the job equally to all the nodes depending on the number of

[OMPI users] How to check that open MPI installed and work correctly

2012-03-25 Thread Hameed Alzahrani
Hi, I installed open MPI on Linux cluster which consist of three machines. I want to ask how can I check that open MPI work correctly and is there a special configurations that I need to set to make the machines connect to each other because I just installed open MPI without making extra confi
