Hi all, Thanks Durga for your reply.
Jeff, once you wrote code for Mandelbrot set to demonstrate fault tolerance in LAM-MPI. i. e. killing any slave process doesn't affect others. Exact behaviour I am looking for in Open MPI. I attempted, but no luck. Can you please tell how to write such programs in Open MPI. Thanks in advance.
