Jan, It looked good, but unfortunately this is a PBS-only extension, and most of our resources (specifically, the one the user in question wants most), are using SGE.
You know, my users say, "Why should I do job submission via Globus? Why not just gsissh in and do a job submission to the cluster's job manager?" My answer has been "Ah, because the Globus way abstracts away all the details of the cluster's job manager---you just write one job description for Globus, and voilà, it runs on all Grid clusters". If in fact the user has to write different job descriptions for each job manager on each cluster... ... what is the correct answer to this question? Thanks!
