CPU Affinity is available inside the kernel only, and is not exposed to
userland.
There are no plans to make it available to userland.

Hi Elias,
Why do you want to do the operating system duty in user level programs?
Kind regards,

Hi,
I was trying to port mprime to OpenBSD.
The main issue is not finding any way to set affinity on cores.
Searching for how to do this on OpenBSD bring this result in undeadly:

It sounds unlikely that CPU congestion is responsible for 5 s network
delays unless your hardware is significantly under
, sometimes even
5 sec on 1G network.
so, I'm looking into optimal "em" tuning and cpu affinity things.
disk io is not affected.

OpenBSD is not a real-time OS.
As far as I know there's no intention to make it
I meant OpenBSD feature to use only CPU00 for network things.
and I am afraid it could cause network issues when some process works on
CPU00 as well.

I've seen situations where it has been useful to dedicate a core to a backup
process so the nightly backup would complete, on a busy linux
machine, with a "cpuset".
If this isn't a planned feature in the near future it's not bothering me.
I'm very happy with what OpenBSD does for me.

I'm trying to keep CPU00 for network things, and avoid using it for user
applications (there're lots of CPUs).
is it possible to achive it without CPU affinity ?

Hello!
I'm investigating how program should set cpu affinity, is there any
examples ? (I didn't find any except the "commit that adds cpu affinity
thing", but there's no user space documentation, no utility, no man page).
cheers,
