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

["Matt Hope" <Matt.Hope@xxxxxxxxxxxxxxx>]

The OpSys, Arch, Disk and Memory requirements are all auto added by the submission if not explicitly stated

 

Disabling this is as simple as adding Foo =!= false to your submit script for  eaxh variable listed above.(none of the above should evaluate to false)

 

so <normal requirements> && (OpSys =!= false && Arch =!= false && Disk != false && Memory != false)

 

If any of these actually need checking just alter accordingly

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
