Hi,
everyone, my opetating system is Redhat Linux as4.0, on a cluster computers. I am just common user and do not have ROOT privilege. I 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?

If I recoll correctly, you should clearly specify hosts for mpirun - either via its configuration file or as a command-line option. But before you should copy your binary to all that hosts. I may be wrong, though.

With respect,
Shawkat
