Urmila, Please send all future emails to [email protected] instead of to individual developers. There could be a number of problems here, including possibly a firewall between the two nodes. Did you try disabling that? Another possibility is that the /etc/hosts file on one or both the nodes is messed up. Did you check that? There should be more information on the mpich FAQ page, which I can't seem to reach right now. http://wiki.mpich.org/mpich/index.php/Frequently_Asked_Questions -- Pavan On 08/17/2013 02:09 PM, urmila pol wrote:
