Re: [HTCondor-users] Non-condor Memory Usage Incorrectly Displayed

This is expected behavior.   The available memory reported by HTCondor is set by configuration, if not set by configuration it defaults to ‘all of the memory’.   No attempt is made to discover other users of memory besides HTCondor jobs – it is up to the configurator of HTCondor to do that if that is desired.

Subject: [HTCondor-users] Non-condor Memory Usage Incorrectly Displayed

 

Hello Everyone,

 

This might be a misunderstanding on my part but I am seeing some unexpected behavior in regards to Condor’s reporting of memory on a Windows exec.  Currently we have a bigger memory box (512GB) that Condor is reporting has all its memory available via condor_status:

Name               OpSys      Arch   State     Activity LoadAv Mem     ActvtyTime

 

slot1@xxxxxxx WINDOWS    X86_64 Owner     Idle      0.130 524274  0+00:32:32

 

However when I look on the box itself I can see that some user is actually using ~300GB of the available memory.  I would expect condor to report that the available memory is actually ~200GB and not schedule any jobs that request more than the actual available memory.  However a simple job requesting 400GB of memory will successfully run on this box.  Is this expected behavior?  Am I misunderstanding how Condor handles available memory.

 

 

Some useful information regarding the exec

Condor version: 8.4.3

Partionable slots

OS: Windows 2012 R2

 

Please let me know if more info is needed
