Re: [Condor-users] How is Requirements expression constructed?



Thanks John and Matt! Yes, I see now that it had to do with a new cluster and a new machine. Is this feature noted somewhere in the manual? I didn't see it, but I was perusing rather quickly. ;-(

To my knowledge this has been a feature of COndor for some time. If you
don't specify Arch and/or OpSys, condor provides one for you and will default
to the same Arch/OpSys as the submitting machine.
 
As well as upgrading to 7.2, have you also upgraded your submitting machine?

Subject: [Condor-users] How is Requirements _expression_ constructed?

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
