[Condor-users] How is Requirements expression constructed?

[Stephen Upton <scupton@xxxxxxx>]

Hi All,

I recently upgraded from 6.8 to 7.2 and I had jobs that remained idle in the queue. Using 'condor_q -better', I found out that the requirements _expression_ included the architecture of the host (X86_64) and I previously only had to specify OpSys = WINNT51, with no Arch _expression_. Well, I also just installed this on a new Linux host as well, but I still don't see in the manual or otherwise, how the requirements _expression_ is constructed. I looked in both the global and local config files, but still don't see how condor construct this _expression_. Once I added 'Arch == "INTEL"' in my submit file, all the jobs worked fine. Adding it there is not a problem, since I think it's a little more explicit, but was curious if I'm missing something (likely! ;-) or if adding it to your submit file is better practice.

thanx

steve
