I think that you need to install Open MPI into other machine as well.
You might want to setup NSF (network file system) for the master (you are
saying your local machine) so that your slave nodes could see your

This error might go away if you install Open MPI into all machines.

it returns right result! but still only 2 local processes.
I tried again to add a hostfile option "--hostfile $HOME/openmpi/bin/hostfile" to
mpirun, with the hostfile containning two items: IA64_node0 and IA64_node1 ,but
this time it complained:
[time returned by IA64_node0]
bash line 1: orted : command not found
oops,did I do a misconfig for openmpi?
btw,openmpi was installed under HOME directory of user semper on each node of the
cluster. The 4 nodes can "ssh" or "rsh" login in each other without password
