Hi George & Allan
First of all i would like to thanks George, for the information. I think with this i can further imporve the performance of my cluster. I was wondering if there is any manual available where all these parameters are listed out. So then i can experiment with them.
Allan i would like to bring to your notice the benchmark results i posted here http://www.open-mpi.org/community/lists/users/2006/03/0875.php
Maybe this could answer your query as to why you were not getting improved performance.
Thanks
Jayabrata
