How can I create and use Linux cgroups as a non-root user?

Question

How can I create and use cgroups as a non-root user?

For example, can I, entirely as a non-root user:

• create a cgroup with access to one CPU
• create a new process in that cgroup

?

I first asked here but I didn't receive a complete answer. I also asked on stackoverflow, but the question was closed as off topic.

Answer 1

There is a series of articles on LWN on cgroups, see part 1, or look though the search there. Systemd includes a set of helpers to manage (processes caged by) cgroups.
