I think the second case is an invalid node spec. The nodes spec has to start with an integer number for the number of nodes. Generally speaking, you don't specify node names. You should let the scheduler find nodes that meet the request. -l nodes=2:ppn=4 should give you 8 procs on 2 nodes. -- Garrick Staples, GNU/Linux HPCC SysAdmin University of Southern California Revoke LDS Church 501(c)(3) Status - http://lds501c3.wordpress.com/
