[Mauiusers] Floating resources not working properly

Actually, I tried that. I ran into two very severe limitations. First, it won't let me specify more than 3 different resources...any more than that and it ignores them. We have 8(!!!) different tape types. Also, even when I got 2 tape types working, using the method you described, consumption doesn't work beyond the first resource. Ie, if I have 5 type atl4 tapes, and submit six job, you get the expected behavior. 5 jobs run, and the sixth is queued. However, when you submit 6 jobs asking for the second tape type, atl5, all 6 queue up and never run.
As for the "qsub -W x=GRES:atl4", unfortunately that didn't do anything either. So far the only secret sauce is "software=XXX". :(

I ran into something like this just last week. A workaround which
worked for me was to specify each resources separately, e.g.:
This clearly doesn't agree with what's in the documentation, but it

What about "qsub -W x=GRES:atl4"?
