If you check the documentation that comes with Scyld Beowulf, you will see we have a different system for chosing which nodes to run on. There's a default setting which works pretty nicely, plus some environment variables you can modify to adjust how many nodes or processors to run on, wether or not to run a job on the master, and an exact listing of nodes if you want. You might want to try that and see if it gives you any better luck with the SMP nodes. -------------- next part -------------- A non-text attachment was scrubbed...
