dee 🏳️⚧️ (nprofile…8er8) Very few things are native NUMA aware :(
yet platforms have become very NUMA heavy (even if they dont explicitly expose it at NUMA nodes), EYPC 9XXX SKUs in even a single socket config can expose their NUMA nodes to help you get the most out of the socket by keeping your memory on the same CCD.
Assuming your workload is massively parallel it's extremely worth the lift to make it NUMA aware if a ~7% CPU "time" reduction would be a big deal.
(Also, the newer Intel parts will have the same quirks as they go for CCD style setups too)
