You are absolutely correct. I am using rsh/ssh based start-up mechanism.
A batch/queueing system might be able to tell you whether a remote computer

Right now I don't have any Idea about batch/queuing system, I will explore
about that also. And I think you mean it before launching the jobs.

I will think about these also.
I have already spent significant amount of time in LAM-MPI and OPEN-MPI and
due to lack of time I don't want to switch to another mechanism. Anyway Open
MPI is doing great for me, Atleast 80% what I want.
Thanks & Regards,
