If i mpirun the MPI application--'hello world' on a single computer(dual core)
itself, it is work. But it can't be successful when i mpirun it across multiple
nodes. The rsh/ssh agent is work, i can rsh/ssh to other nodes.Everytime i
mpirun 'hostname' , the remote rsh/ssh agent ask for the password.I enter the
password but the Openmpi is hang. It is just hang and nothing else.
I don't know what happen to my Openmpi enviroment or operating system.
Would you ever encount this problem?

Can you provide a little more information?
What exactly are you trying to mpirun across multiple nodes? Is it an MPI
application or a non-MPI application? For example, can you mpirun "hostname"
(i.e., the Unix hostname utility) across multiple nodes successfully?
If you're trying to mpirun a user application, what application is it? Can
you mpirun a trivial MPI application (e.g., hello world) successfully?
Thanks.

Subject: [OMPI users] rsh/ssh is work but mpirun hang ?
I have installed the openmpi -1.0.2 on the Fedora Core5 operating system. I
use the Intel Fortran compiler. I can rsh/ssh to the other processor in our
cluster( 2 PC's , 4cores). I can mpirun on a processor itself successfully.
When i mpirun on 2 PC's, after entering the password, the program will be
hung!
Does anyone encounter this problem?How do i check and fix it?
Thanks in advance
Vincent
