Were these configured for NUMA, or non-NUMA?
I've not gotten my hands on a TR3. But rome gives you the option of 1, 2 or 3 Nodes Per Socket. Various benchmarks (eg, stream) published by vendors such as Dell show better performance in 4NPS mode. My own testing on Netflix workloads shows a similar speedup.
I run my dekstop (2990WX) in numa mode, exposing the real topology to the scheduler, and I find that it seems to help compilation times.
- stagger87 7y agoThe issues surrounding NUMA are addressed extensively in the article.
- drewg123 7y agoNo, not really. They're discussing windows "processor groups" which seem to be arbitrarily created for chips with 64 or more SMT threads. That's why i'm wondering if 2-NPS or 4-NPS is available with TR3, and what impact it would have.
- bitL 7y agoIn general, in Linux it's best to run TR1 and TR2 in NUMA mode. Not sure about TR3.
