I'm trying to create really simple "cluster" from 2 multicore computers using openmpi.

My problem is that I can't find any tutorials on that matter. I don't want to use torque because it's not necessary in my case nevertheless all tutorials give configuration details either about torque or mpd (which doesn't exist in openmpi implementation).

Could you give me some tips or links to appropriate manuals?

Steps I've already completed:
- openmpi installation
- network configuration (computers see each other)
- ssh password-less login to second computer

I tried using machinefiles without further configuration and with just 2 IPs in it. But jobs don't seem to start at all after initialization part. (MPI seems to work because I'm able to scatter jobs on multiple cores of both computers without communication between them).
