I found one way to run PVM.

On the Master, edit the inetd.conf and uncomment the rshd and 
rlogin parts. 
a 'killall -HUP inetd.conf' to re-read the file.

Prepare a suitable /etc/exports file to allow the nodes to have 
nfs access.

Prepare a suitable .rhosts file in $HOME to rsh without a 

The following commands should then be run:

bpsh <n> hostname <hostname> for each of your nodes. I do this 
friendliness though it is not necessary. You will need a suitable 
file if
you use this method.

Mount the following:

bpsh -a mount -t nfs -n /home (if not mounted 
bpsh -a mount -t nfs -n /etc
bpsh -a mount -t nfs -n /bin
bpsh -a mount -t nfs -n /usr
bpsh -a mount -t nfs -n /lib

The -n flag stops any problems with mtab.

Run bpsh -a /usr/sbin/inetd

Start a pvm session on the master and then add your nodes by 
hostname. Once 
check pvm>conf to see that all is in order.

This is very much the long way round and should really be
