Hi,

The hostfile comes from the batch system; it just contains the
unqualified host names:

    $ cat $TMPDIR/machines
    nh64-1-17
    nh64-1-17

No problem if we modify the setup script to create the hostfile using
FQDNs instead. (`uname -n` returns the FQDN, not the unqualified host name.)

Thanks,
Riccardo
