Dear Slurm Users, I have a question regarding the energy consumption of a node during application execution.
Following is the output from a job executed on one node. ============================================================ *$ scontrol show job 13513617* JobId=13513617 JobName=dgemm ... JobState=COMPLETED Reason=None Dependency=(null) Requeue=1 Restarts=0 BatchFlag=1 Reboot=0 ExitCode=0:0 RunTime=00:00:31 TimeLimit=00:30:00 TimeMin=N/A SubmitTime=2020-02-06T13:26:35 EligibleTime=2020-02-06T13:26:35 AccrueTime=2020-02-06T13:26:35 StartTime=2020-02-06T13:26:36 EndTime=2020-02-06T13:27:07 Deadline=N/A SuspendTime=None SecsPreSuspend=0 LastSchedEval=2020-02-06T13:26:36 Partition=workq AllocNode:Sid=cdl2:17930 ReqNodeList=(null) ExcNodeList=(null) NodeList=nid00024 BatchHost=nid00024 NumNodes=1 NumCPUs=64 NumTasks=0 CPUs/Task=1 ReqB:S:C:T=0:0:*:* * TRES=cpu=64,mem=128448M,energy=9429,node=1,billing=64* Socks/Node=* NtasksPerN:B:S:C=0:0:*:* CoreSpec=* MinCPUsNode=1 MinMemoryCPU=2007M MinTmpDiskNode=0 Features=(null) DelayBoot=00:00:00 OverSubscribe=NO Contiguous=0 Licenses=(null) Network=(null) ... Power= ============================================================ The Trackable RESources (TRES) line is below: * TRES=cpu=64,mem=128448M,energy=9429,node=1,billing=64* Is the energy displayed here the energy consumption of the node during the job execution? Could you please tell me how the energy is calculated? Is it using RAPL or IPMI or external power meters? Many thanks for your help. -- Kind Regards Ravi
