All compute nodes have had a change made to their BIOS to ensure they're operating in 'Max Performance' mode.
|
|
|
|
|
|
|
|
Should new nodes be introduced to the cluster, it's likely they'll need this setting updating.
|
|
|
|
|
|
|
|
Upon build of the OS, the 'onecli' tool is installed which will allow you to apply BIOS changes from the operating system.
|
|
|
|
|
|
|
|
The following command will set the BIOS to max performance:
|
|
|
|
|
|
|
|
`onecli config OperatingModes.ChooseOperatingMode="Custom Mode"`
|
|
|
|
|
|
|
|
A reboot is then required for this to take effect.
|
|
|
|
|
|
|
|
It is worth noting that in a HPC Environment, Hyperthreading should also be disabled, in this case, the option is called 'SMT' since the CPUs in the cluster are AMD instead of intel
|
|
|
|
|
|
|
|
You can disable SMT by running the following from the OS of the compute node:
|
|
|
|
|
|
|
|
` onecli config set Processors.SMTMode Disable`
|
|
|
|
|
|
|
|
The onecli commands can both be issued one after the other and a single reboot will apply them |
