Well almost there now. I had to shut down iptables on the playstation, the 
random port forwarding that MPI wants to set up did not really work for 
some reason. Without firewall it works.

But now it crashes with:

DiFX Generic CPU Version
About to run MPIInit
p2_859:  p4_error: Could not allocate memory for commandline args: 
889192448
rm_l_2_871: (1.829863) net_send: could not write to fd=5, errno = 32

rm_l_3_886: (1.346863) net_send: could not write to fd=5, errno = 32

Any ideas?

I'm using p4, by the way. And starting the process with
$ declare -x P4_RSHCOMMAND="ssh"
$ declare -x RSHCOMMAND="ssh"
$ mpirun -v -np 6 -machinefile /nfs/mpitest/machines.CLUSTER 
/usr/bin/mpitest /nfs/mpitest/data.in.cfg

Wasn't MPICH-1 supposed to be for heterogenous clusters too?
