maybe Joe means this:
which is being updated for SGE 6.* I basically hacked it
together because I could not easily understand qstat.
Source is available, be advised code is ugly as it
started out as hack while I was debugging SGE parallel
environments and test suites.
I should have a new version "real soon now" there are also
some web based tools that do this for SGE as well
