Raptor Lake efficiency cores in Linix with Docker?

[fmstrat@lemmy.nowsci.com]

Hey all,

Anyone familiar with the state of Raptor Lake performance + efficiency cores in Linux? I'm specifically curious about how the kernel balances things when running multiple containers (without pinned CPUs)

Thanks!

Looks like you'd have to manually assign cpus by with --cpuset-cpus

What makes you say that?

[maniel@lemmy.ml]

A quick look at docker docs says it's the only way. Same with any other way of running a program/service, you have to manually set an affinity of an executable

No you don't? There's nothing with Docker that forces you to pin.

I didn't say it's forced, it's the only way I know of to force usage of specific threads/cores, that's all
