In the BIOS of the compute nodes, set the CPU to Performance mode for best performance. For more details, see the Dell PowerEdge 16G Server BIOS Settings for Optimized Performance.
The following CPUfreq governor types are available in Red Hat Enterprise Linux 8. Check other operating-system-specific governors if you are not using CentOS or Red Hat Enterprise Linux 7.
Governor type | Description |
cpufreq_performance | Forces the CPU to use the highest possible clock frequency. It is meant for heavy workloads. This type is a best fit for interactive workloads. |
Cpufreq_powersave | Forces the CPU to stay at the lowest clock frequency possible. |
Cpufreq_ondemand | This allows CPU frequency to scale to maximum under heavy load but drops down to lowest frequency under light or no load. This is the ideal governor and subject to appropriate testing, and can be used (because it will reduce power consumption under low load or idle conditions). |
Cpufreq_userspace | This allows user space programs to set the frequency. This is used with the cpuspeed daemon. |
Cpufreq_conservative | Similar to the cpufreq_ondemand but it switches frequencies more gradually. |
Find the appropriate kernel modules available on the system, and use modprobe to add the driver needed:
# modprobe cpufreq_performance
After a particular governor is loaded into the kernel, enable it using the following command:
# cpupower frequency-set –governor cpufreq_performance
