@Gus: According to the documentation, Schrodinger software should only run good on MPICH1, otherwise I'd have preferred MPICH2.<br><br>@Tom: Yeah I know I could do that, I could assign the IP address, that worked, but the hostname just didn't work, so I didn't bother. I did check the option for it to configure hostname via DHCP, and I also configured my server to give out hostnames, it just didn't work. I made the startup scripts assign the hostname according to the IP address, and it seems the server is giving out the IP addresses according to the MAC address already. Its not going on in the order.<br>
<br>@John: I knew that, it is not the issue I am having problems with.<br>
