[openib-general] Topspin Errors

[Srirangam Addepalli]

Hello,
 I have two three machines connected with out a switch, i can ping from all 
three to the others. How ever when i try a mpirun_ssh i get into errors. Are 
there any particular steps i need to look at if not using a switch.
 Thankyou
 Rangam
