Default cpuset for 5.3
Hi All,

I'm looking for functionality similar to "cpuset" but for FreeBSD 5.3. I want to lock a given process to a specific core or specific cores. I wouldn't be opposed to minor patching/kernel tweaking/rebuilding/whatever if needed. Just not sure what the available options are. Thank for any input on this.

Thanks, but that's not an option at this point.

You can't expect 'minor kernel patching' when the kernel source code is two major versions behind the one that first featured (the entire family of system calls associated with) cpuset(2) (7.1).

Uhh.. yeah, I know that. I don't believe I implied that I thought moving up to 7.1 was my option. I'm asking for other possible solutions - "similiar to cpuset but for FreeBSD 5.3."

coleb, you might be able to run the process from a jail, and limit the CPU shares for the jail.

This is a little on the 'hack' side, but it may work.

Upgrading to a newer version of FreeBSD would probably be your best option overall, though.
