A chess wish

[kgburcham]

I wish Houdini, Fire, and Stockfish would run 12 threads.

Your wish can be granted .
I can compile a 12-thread x64 Houdini development version, optionally with Large Page support, if you like.

Why not directly to for example 512 cores/threads version!!

Or a automatic core/thread setting!

ok thanks. i will post results once you tell me it is ready.

I noticed some smp programs go immediately to 100% usage in task manager on all threads and stay at exactly 100%. some programs do not. Some will show it is using 12 threads 100% of the time but not 100% of each core.

Some programs may have some threads waiting with a "loop" (busy but acturally doing nothing) and others (like gaviota) wait without using the CPU. That is why CPU usage may not be a good measure of efficiency. A car waiting in red light with the engine on or off is still waiting. How the NPS scales up may give a better idea, but still... The best will be time to reach a certain depth in several positions.
