Life In 19x19

In my test matches I always use one search thread for the optimized network in BadukAI because:

1) Almost all calculations are done on the NPU which exists only once, so you don't gain significant speed with more threads, so why use them ?

2) Due to the above SW architecture, one thread may be blocked by the other for a lot of playouts, which can have very bad effects on the search process, so might lose significant strength.

BadukAI 40b optimized version 1.13.2 (maxPlayouts 15, numSearchThreads 2) - Sabaki 40b s1110 (maxPlayouts 10, numSearchThreads 2) 1:1
