Yep, if the HP 9000 cluster has a shared /tmp directory then you have
to compile PVM with -DSHAREDTMP.
This is necessary because PVM put a lock file in /tmp (/tmp/pvmd.<uid>)
and if this file already exists when trying to start pvmd then it isn't
started.  This means that only one pvmd can be started in a cluster
with shared /tmp - unless PVM is compiled as mentioned above.

Hope this helps.
