Subject: Re: [RFC PATCH v1] pin_on_cpu: Introduce thread CPU pinning system call
Date: Wed, 22 Jan 2020 16:48:06 +0100 [thread overview]
Message-ID: <CAODFU0pi6MVJ+XgUmZRS_+ihAyZF+aq_V7sdnbeNeDtPzCZS=A@mail.gmail.com> (raw)
Hello
I would like to note that this does not help userspace to express
dynamic scheduling relationships among processes/threads such as "do
not run processes A and B on the same core" or "run processes A and B
on cores sharing the same L2 cache".
Sincerely
Jan
