Re: [HTCondor-users] Steer job towards high memory nodes

Maybe the recursion is confusing it? Try defining a âhighmemory-rankâ value with the if statement, and then adding it to the negotiator_pre_job_rank sum.

Hello Experts,

 

I want to steer jobs with memory greater than 5342MB to highmemory nodes. HighMemory is added to machine classAD and value is either true or false. 

 

_expression_ used to achieve this: 

 

NEGOTIATOR_PRE_JOB_RANK = $(machine_rank) \
                        + $(disk_speed_rank) \
                        - $(cpu_utilization_rank) \
                        - $(disk_utilization_rank) \
                        + $(memory_rank) \
                        - totalcpus

 

NEGOTIATOR_PRE_JOB_RANK = ifthenelse(requestmemory > 5342 && requestcpus == 1, $(NEGOTIATOR_PRE_JOB_RANK) + 1000000 * (HighMemory =?= true), $(NEGOTIATOR_PRE_JOB_RANK) + (HighMemory =!= true))

 

But still jobs with high request memory like 7000 MB going to machines with machine classAD of  "HighMemory false". 

 

It's partitionable slot setup with scheduler splitting enabled. I want to avoid injecting the hard requirement for high memory node in submit file. 

 

Can anyone please help to understand what is wrong here.

Thanks & Regards,
