Hi,

I need to disable TurboCore/Core Performance Boost in two nodes (clgpu022 and clgpu023) in my experiment (u1266544-QV96224), as well as C States. I cannot access the file /sys/devices/system/cpu/cpufreq/boost as it does not exist, which leads me to believe it needs to be shut off in the BIOS. Similarly, I believe that C States also need to be disabled in the BIOS. How can I go about doing that? If this is not the way, do you have any resources on how could disable these? I have not had much luck with Google results.

Thanks,

Meghana

I have changed the BIOS on these two nodes. You will need to reboot for
the changes to take effect.

Hi,

I have another new experiment (u1266544-QV97346) that requires the same BIOS modification for nodes clgpu016 and clgpu009. Could I get some help with that?

Thanks,

Meghana

Sorry, I had to delete that experiment and start a new one (u1266544-QV97354), though the nodes remain the same.
