everyone, my opetating system is Redhat Linux as4.0, on a cluster

only have the right to install openmpi in my space of my account,
I have installed open-mpi exe files in /home/myname/bin, *.h files
in /home/myname/include and lib files in /home/myname/lib.
when I run "mpirun", the "mpirun" says it can only find one node
where I have login.
So, should I install open-meep on each node?
But I can login each node, without password, and each node seems
no different to me, and I can run "mpirun" at each node.
why does this happen?
I strongly recommend that you talk to the administrator of your cluster.
Your cluster almost certainly has a version of MPI already installed
and configured properly. And your admin can teach you how to use
mpirun to launch an MPI process on multiple nodes (there is usually a
configuration file that you must specify to tell it which nodes to
run on).
These are all basics of using MPI, not related to Meep in particular,
and it is best if you find a local MPI expert to help you.
