Hi All,
additionally write...
I changed the CPUFreq driver from intel_pstate to acpi-cpufreq.
The result was the same for intel_pstate.
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

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?

Hi all,
I am checking the --cpu-freq option of the sbatch command.
The CPU frequency of the target node is as follows.
