Anything special about the worker?
This machine is an aarch64 Equinix machine and it is currently used to run benchmarks to be uploaded to speed.python.org. Given its spec, we'd like to run also bigmem tests. Tagging @ambv for visibility
Hmm, if it's a benchmark runner, do we really want it running a buildbot as well? It seems that would impact its ability to run benchmarks effectively, or would require routinely stopping the buildbot worker process.
We have set up the machine with cpu isolation. The machine has 80 cores and we have isolated the last 14 cores for running benchmarks: to be precise we run benchmarks just on the odd cores in the range 65-79 (65, 67, 69..) using cpu affinity.
Daily benchmarks are run at midnight (UTC) only, the rest of the time the machine is idle.
The aim is to maximise the use of this machine. If we want to be on the safe side we could pause buildbot jobs 2 hours before and after midnight so it won't be scheduling jobs when benchmarks will be running.
Ok. I'm no expert at benchmarks, so if that configuration is deemed sufficient from that side of things, I'm ok from the buildbot side of things :)
Can you create a PR adding the public configuration? #404 should be a reasonable template to follow, though there may be some extras needed to enable bigmem testing.
I have my hands blocked until this https://discuss.python.org/t/top-level-license-not-present-on-some-repos/47973 gets resolved.
