Andscacs test version

[Jesse Gersenson]

Hi Daniel,

The files could all go in a folder named /andscacs:
andscacs/debian
andscacs/centos

running it now on 44 threads on Centos. Will let you know results.

Thanks. The new versions are able to run in any number of cores, so you can use the 90 threads or whatever you use for other engines.

I try to see what happens. I understand that this error does not invalidate Andscacs to play.

Andy crashed after a few days as live evaluation engine at TCEC using the CentOS dev build.
Here is the message from the crash and I guess this was the position it crashed.

Code: Select all

5b2/1R6/2p3k1/R3p2p/4q1p1/6P1/5P1P/5NK1 w - - 0 45

andscacs[12726]: segfault at 260095d8 ip 000000000041c806 sp 00007fffe00404a8 error 4 in andscacs[400000+b7000]

Might be a hash collision or something, since it is not immediately reproducible.

Daniel, perhaps a UCI option to output debugging into to a log file would be useful.
