[Condor-users] Dynamic Partitioning Updating Memory Usage

[Jake Adriaens <jtadriaens@xxxxxxxx>]

I've configured condor to use dynamic slot partitioning, however the memory size for the dynamic slots are never updated.  When my jobs run, each dynamic slot always has a memory size of 1 and never grows with the image size of the job. It is my understanding that once a dynamic slot is allocated the resources assigned to it cannot change.  To work around this I've tried to configure condor to preempt a job if its image size grows larger than the memory allocated to the slot.  However, my jobs are never preempted even though image size shown by condor_q is considerably larger than the amount of memory available in the dynamic slot as shown by condor_status.  Below are my preemption settings from the condor configuration. Any suggestions would be greatly appreciated.

PREEMPT = True

RAN_FOR_A_BIT = $(StateTimer) > (10 * $(MINUTE))

PRIORITY_EXCEEDED = RemoteUserPrio > SubmittorPrio * 1.2

MEMORY_EXCEEDED = (TARGET.ImageSize/1024*0.7) > (Memory*1.0)

PREEMPTION_REQUIREMENTS = $(RAN_FOR_A_BIT) && ( $(PRIORITY_EXCEEDED) || $(MEMORY_EXCEEDED) )
