[Improvement] Higher than 100% max-threads-hint #400

Take higher than 100% values for max-threads-hint option to quickly adjust used threads count for cases when it wasn't properly detected (in virtualized environment for example), without having to use manual threads config.

Do you've observed that somewhere or is that an assumption?

I do, happens on my 2x7702 behind eSXI 7.0.1 with rx/0. It automatically uses only 32 threads per socket, not sure if that's how it's supposed to be but settings it to use 64 threads increases the hashrate significantly.

Hmm, sounds like an issue detecting the 2nd socket then..

Nevermind. The epyc 7702 has 128t and 256mb l3, so it should run fine with 128t per socket?

It runs worse in my case with 128T per socket, 64T gives the best results.
