[mpich-discuss] MPICH@ over SDP

[Pavan Balaji]

Hi Mahesh,

Did you configure SDP to go over any specific IP addresses (e.g., 
tf08ib, tf09ib)?  If yes, you need to make sure that your machine file 
uses a different set of IPs (e.g., tf08 and tf09).  This is because the 
initial setup of the processes happens over ssh and presumably on your 
machine the ssh server (sshd) is not launched over SDP.
