In general it's most efficient to have a job use whole nodes. If you use a partial node, jobs will likely interfere with each other, reducing overall performance. Now if your code only runs on N**2 nodes, using whole nodes can be painful. But with M*N nodes, you're usually OK. -- greg _______________________________________________ Beowulf mailing list, [email protected] sponsored by Penguin Computing To change your subscription (digest mode or unsubscribe) visit http://www.beowulf.org/mailman/listinfo/beowulf
