Hi all, I am checking the --cpu-freq option of the sbatch command. The CPU frequency of the target node is as follows.
# cpupower frequency-info analyzing CPU 0: driver: acpi-cpufreq CPUs which run at the same hardware frequency: 0 CPUs which need to have their frequency coordinated by software: 0 maximum transition latency: 10.0 us hardware limits: 1000 MHz - 2.60 GHz available frequency steps: 2.60 GHz, 2.60 GHz, 2.50 GHz, 2.40 GHz, 2.30 GHz, 2.10 GHz, 2.00 GHz, 1.90 GHz, 1.80 GHz, 1.70 GHz, 1.60 GHz, 1.50 GHz, 1.30 GHz, 1.20 GHz, 1.10 GHz, 1000 MHz available cpufreq governors: conservative userspace powersave ondemand performance current policy: frequency should be within 1000 MHz and 2.60 GHz. The governor "performance" may decide which speed to use within this range. current CPU frequency: 2.60 GHz (asserted by call to hardware) boost state support: Supported: yes Active: yes # Set 'CpuFreqGovernors' in slurm.conf. # scontrol show config | grep CpuFreqGovernors CpuFreqGovernors = Conservative,Performance,PowerSave,OnDemand,UserSpace # And submitted a sleep job. $ cat sleep_60.sh #!/bin/bash #SBATCH -J sleep_60 # Job name #SBATCH -o job.%j.out # Name of stdout output file (%j expands to jobId) prun sleep 60 $ $ sbatch --cpu-freq=1000000-2000000:UserSpace sleep_60.sh Submitted batch job 56 $ squeue -l Thu Oct 3 14:37:04 2019 JOBID PARTITION NAME USER STATE TIME TIME_LIMI NODES NODELIST(REASON) 56 normal sleep_60 test RUNNING 0:03 1-00:00:00 1 ohpc137pbsop-c001 I thought that the value of CPUfreq could be confirmed with the sacct command. However, the value of CPUfreq was Unknown. Why isn't the CPUfreq value displayed as requested value? $ sacct -j 56 -o JobID,Partition,JobName,AveCPUFreq,ReqCPUFreqMin,ReqCPUFreqMax,ReqCPUFre qGov JobID Partition JobName AveCPUFreq ReqCPUFreqMin ReqCPUFreqMax ReqCPUFreqGov ------------ ---------- ---------- ---------- ------------- ------------- ------------- 56 normal sleep_60 Unknown Unknown Unknown $ Regards, Tomo
