Re: [HTCondor-users] Why doesn't HTCondor-CE support the standard RequestMemory attribute?

[KÃhn, Max (SCC) <max.fischer@xxxxxxx>]

Hi Jaime,

I was suspecting something like this. Thanks for the confirmation and considering this!

FWIW, I was considering to check for the default value by temporarily setting `MemoryUsage` to some sentinel (either a random number or ERROR) and checking that `RequestMemory` reflects that.

Cheers,
Max

That value was too small and so the jobs would fail. There wasnât a good way in the CE to detect if the value was the default supplied by condor_submit, so we deicded to always ignore it. The factories for glideins always use the attribute maxMemory, which the CE copies to RequestMemory, so they werenât affected by the change.
