The speed is only 1k~2k N/s for the mid and endgame, which is slower than the Senpai running on my laptop using 1 core....
Looking at the ongoing game "Senpai 1 - Komodo 8" at TCEC, the speed of Senpai there (-- running at 16 cores) is much slower than Senpai running on my i7 4700MQ, from position after move 15.
Thanks for the report. This forced me to file a bug report myself!
Actually I tested Senpai in March/April and luckily at that time I only used fast tc with 1 thread and 128MB hash under CuteCli and had not much problems(I vaguely remembered unloading problems in various GUIs though).
Now I wanted to reproduce something with more threads after reading your report.
To my surprise there were lots of problems and due to completely different conditions(WB GUI - different hash - different threads number) I needed quite a while to figure out what causes them.
Finally I found out that Senpai crashes before move 1 when threads is set >1 in game mode(around depth 13/14).
Moreover it does not crash in analysis mode but always shows only usage of 1 thread independent from the setting(e.g. 2,4).
NOTE: This is the 32bit compile which was offered in this thread and here it is used under WINXP on a Quadcore from 2011.
Error happens at 0x00035acd and/or 0x00000000 according to the crash reports from windows. Not sure if the second is real.

Are there other 32bit compiles for XP I could test?
