Andscacs test version

Post by cdani » Sun Dec 09, 2018 11:47 am

Hello!
Maybe someone can test if this test version of Andscacs scales well in nps with more than 64 threads in Windows?

Also included is a Linux version that should work well, using events instead of sleep for the waiting threads (Windows version already had this for quite some time), and maybe someone can test it also, better with a lot of threads :-).

http://www.andscacs.com/downloads/andscacs094157.zip

This test version should be more than 20 elo stronger in selfplay than 0.94.
Thanks!!

The linux version was Ubuntu. I added to the same file a Centos 7 version. Otherwise it said GLIBC... not found.

I have tested the CentOS version and seems to scale without problem with 128 cores.

Does this mean we will see Andscacs 0.95 playing in the TCEC Premier Division?

Will it be possible for the engine to use endgame tablebases?

Yes, is the most probable.

Will be nice, but for the moment I don't want to spend time on this, as I have too much other ideas to try.
