Get rid of the 'ncpus' piece (by changing the job scripts and/or 
server/queue parameters with qmgr). I can't tell you why exactly, but I am 
quite sure that ncpus caused problems for me in the past. I'm also 
completely sure that this attribute is not needed (based on our 
TORQUE+Maui installation, which successfully runs a mix of single and 
multi-processor jobs).
