Re: [Condor-users] Reseting the ImageSize

[Alan Malta <alanmalta@xxxxxxxxx>]

Hi Dan,

thank you for the prompt response. I changed the ImageSize, in fact I tried, but the command didn't ended with code 0. Also, I messed up the whole system, so it was necessary restart the services to be able to see again the status of the schedd and jobs.

I'm not sure I understood what you meant about adjust advertised memory needed. The requirements to allow that jobs can run here, are:
Requirements = (OpSys == "LINUX" && Arch == "INTEL") && (Disk >= DiskUsage) && ((Memory * 1024) >= ImageSize) && (HasFileTransfer)

It's not clear to me what will happen if I use '(Memory > 1000)' or '(Memory > 10)', because the job ImageSize still will be greater than 2GB available per job (ImageSize = 2500000, in this case).

Thanks,
Alan.

Hi Alan,

and
http://www.cs.wisc.edu/condor/manual/v7.3/7_3Running_Condor.html#SECTION008312000000000000000

It looks like you want to use:

condor_qedit Requirements 'ImageSize == 0'

but I'm not sure that this is a good idea.
Rather than messing with ImageSize, why not just adjust the advertised memory needed?

condor_qedit Requirements '(Memory > 1000)'

or similar..
