Put it under Linux.  It is a Linux representation of Windows11.  And it is legal to use.

If I wasn't already doing ok with Ubuntu for crunching I might be tempted. But I would lose Keith and Ian&SteveC's expertise and support if I did switch.

This seems to indicate the default CPU scheduler should be different than what it is. What not clear is would it make a difference on boinc CPU projects.

Well we currently use the cpufreq scheduler which is based on the 20 year old CFS scheduler.  The devs have been wanting to update the scheduler to better use all the improvements in technology and architecture.

20 years ago, multi-core cpus didn't exist.

If you are runing Ubuntu 20 or 22 then you are using the acpu-cpufreq scheduler with either the on-demand governor for Ubu 20 or the schedutil governor for Ubu 22.

They are trying to come up with a better scheduler for AMD called p-state but the older acpi scheduler is still better than most of the p-state governors.  It might get better in the future once they work out the kinks.

If you just select the performance governor, no matter whether the older acpi-cpufreq or the p-state version you will get the best BOINC performance.

What is default is chosen for the most popular platform which is the laptop and general purpose PC.  Our BOINC hosts are far from the generic use case.

So this is how to set it to performance mode?

I never found that changing

I never found that changing the governor from default to performance made any difference for BOINC. Same clocks and same runtimes either way.

Doesn't make any difference for the hosts that run overclocked at a locked all-core clock, but absolutely makes a big difference on the Epyc hosts.

I’m including the Epyc hosts they run the same either way.

Well I just looked again on my Milan cpu and I lose 500Mhz on each core flipping back and forth between Performance and OnDemand.

2.63Ghz >> 2.57Ghz

Did you see this that came out today:

"

Zorin OS 16.2 is now powered by the same version of the Linux kernel as in Ubuntu 22.04 and comes with new drivers, bringing even better support for hardware such as:

  • NVIDIA graphics cards, including the GeForce RTX 4090
  • AMD Radeon and Intel graphics cards"

I wonder if that means more people will be trying it so they can run either type of gpu with fewer problems?
