You are absolutely correct. I am using rsh/ssh based start-up mechanism.

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, -- Vipin K. Research Engineer, C-DOTB, India
