I'm not too familiar with that tutorial nor your particular method of
installation. In general, Open MPI needs a bunch of files to be
available on all nodes (e.g., see if you can find "mpirun" on all
nodes). See these FAQ entries:

I followed the steps given here to setup up openMPI cluster :
http://www.ps3cluster.umassd.edu/step3mpi.html
My cluster consists of two nodes, master(running on fedora 10) and
compute(CentOS 5.2) node, connected directly through a cross cable.
I installed openmpi on both, there were many folders n files on de
master node but there were none on de compute node. i again ran yum
install openmpi successfully on de compute node but still there were
no openmpi folders or files installed.
Why is this happening? is it because of the OS?
