Hi

I'm having trouble running mpi jobs when  nodes=x with x greater than the number of cores per node. The system comprises 14 nodes with 8 cores/cpus each. When x > 8 it seems to only have entries for the last node, ie 4 lines if I use "-l nodes=12". I've tried various combinations with "nodes=x:ppn=y" as well, no luck. What could be wrong?

Thanks in advance
Gordon
