Nope, this isn't to do with scheduling, just if you
do build Torque with --enable-cpuset (not the default)
then jobs may fail when they are scheduled as I am
guessing that pbs_mom will get confused about trying
to allocate cores that don't exist.

This shouldn't happen in the default case where
the --enable-cpuset option isn't set.

cheers,
Chris
