Scyld Beowulf clusters replace rsh and other methods of launching jobs via a distributed process space. There is no need for a nodelist file or any special daemons. In order to allow access to files, the first NAMD process must be on the master node of the cluster. Launch jobs from the master node of the cluster via the command:
charmrun namd2 +p<procs> <configfile>
For best performance, run a single NAMD job on all available nodes and
never run multiple NAMD jobs at the same time. You may safely suspend
and resume a running NAMD job on a Scyld Beowulf using control-Z or
kill -STOP and kill -CONT on the charmrun process.
