Hello,
I'm trying to get SunGrid to manage licenses, like the pam_crash example.
Though it seem to track the resource on a host by host basis, instead of on a Q basis.
I have a small setup, 3 hosts, 3 licenses. I'm trying to limit the number to 2, but it takes 2 per host. I tried setting consumable to Jobs as well as yes, but same difference.
Hope this question makes sense, and there's a way to get this done.
Host group?
Cheers,
Ric
