Re: [HTCondor-users] Counting job num of holds for a given reason

Thanks Todd. I wasnât thinking about using MemoryUsage but instead trying to work with NumSystemHolds and NumJobStarts. I think your approach will work and let me do the periodic release exactly once.

    No easy way to have a counter like you ask above, but I think you could still achieve the policy you want (only increase the memory once).  How about a submit file like the following?  I didn't test it, but I think it will demonstrate the gist of what you want.  The trick it to record the initial memory request in the ad, and then compare the current memory request to the initial request to decide when to stop releasing the job instead of relying on a (non-existent) counter.
    
      executable = foo.exe
      +initial_memory = 256
      request_memory = ifthenelse(isUndefined(MemoryUsage),initial_memory,2*MemoryUsage)
      periodic_release = (HoldReasonCode =?= 34) && (request_memory < (2 * initial_memory))
      
    regards,
    Todd
