Sounds like a typical problem with the p4 libraries when the account isn't setup properly. Try executing the following rsh localhost ls If it gives "permission denied", then you know that is the problem. The easiest fix is to add the user to the .rhost file. I wouldn't recommend doing this for root. GB wrote: > > Hi. I just installed MPICH on our lab's SGI Indigo2 R10000 (IRIX > 6.4).
