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? Vincent "Jeff Squyres (jsquyres)" <jsquy...@cisco.com> 說: 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?

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?
