A Tour Of Cgroup2 Resource Control With Resctl-Demo

Recorded June 9, 2021

View A Tour of cgroup2 Resource Control with resctl-demo, with Tejun Heo, Software Engineer at Facebook.

We all want to use our machines reliably and efficiently. We don’t want our build jobs to stomp over the web browser, or a periodic maintenance task to interfere with the revenue generating latency-sensitive service. It’d also be nice if the hot spare capacities we keep around for lower latencies and emergencies can be used for something productive transparently.

Resource control on Linux can now achieve all of the above and many parts are in wide production use at Facebook. We learned a lot of lessons and subtleties the hard way and documented them in [resctl-demo] (https://github.com/facebookexperimental/resctl-demo).

This session walks through various resource control topics using [resctl-demo] (https://github.com/facebookexperimental/resctl-demo).

The session begins with an overview by Tejun Heo (45 minutes) and is followed by Q&A.
