we've done this kind of color-job band before, and found that
it was difficult to read. another approach is to show jobs
as logical blocks, rather than cpus mapped directly to y-axis:
admittedly, that's not terribly pretty. and MPI implementations
that busy-wait make the %cpu report less useful than it might be.

we run LSF, a home-grown scheduler and Maui on ~21 clusters,
and feed job data into a central DB which permanently records all
history. graphs like above (and others that show various usage
metrics by user/group/cluster/jobsize/jobtype) are derived from the DB.
