Not really. We don't have access to a PA RISC system. Are you using HPUX
or Linux?

Rajeev,

I ran /usr/local/sbin/mpeunistall, make clean and then re-configured
with the ch3:sock device, built and installed it OK but I'm still
getting com errors albeit less errors this time. Any more thoughts?

Can you try configuring with --with-device=ch3:sock and see if that
works?

I have been struggling with communication errors when ever I run
mpiexec. This installation is on PARISC based cluster. Running
mpich2-1.2.1p1, I have configured it with --with-device=ch3:nemesis. 

Currently only 2 nodes are in the ring, hp20 and hp14 for testing/setup
purposes.

The following steps may shed some light on the problem, which I'm sure
is something I have omitted or failed to do with the initial
installation/configuration. It appears that I can run non MPI programs
OK, but MPI code like cpi or hello fail.
