[torqueusers] scheduling on CPU usage

Admittedly, I'm pretty new to the Torque admin world, but is there a
simple way schedule jobs to a node based on the CPU usage? I've found
the "$ideal_load" and "$max_load" parameters for the MOM, but, unless
I'm mistaken, these appear to refer to the load average, not the CPU
usage. Load Average and CPU usage are often related, but not always.
Just for background, I'm working on a project that needs to schedule
jobs whose length (walltime, etc.) varies widely, but will very often be
a fraction of a second. We still want to get as much utilization out of
the compute nodes as possible, but are finding that there's a lot of
unused cycles since the jobs are so short in relation to the apparent
timing resolution. If anyone has any other ideas for scheduling large
numbers of extremely short jobs, I'd listen to those too.
