Two changes:
(1) pawn island evaluation term removed. Cluster testing with 32,000 games showed this to be worth +14 Elo to remove it.
(2) bug Dann found earlier has been fixed, but in a different way from what he had tried because the Malloc() need to be done by each individual thread for NUMA reasons... this should solve the problem of compiling with CPUS=4 or whatever, but running with < 4 threads, which is what would produce the segfault.

New builds are on my site as well.
I was kicked out of Chapters because I moved all the Bibles to the fiction section.

Re: Crafty 22.4 is now available
some 500,000 games played this last week has helped a good bit. The cluster testing is actually working, and quite well... There is more to come...gerold wrote:Thanks again Robert and Peter..Peter Skinner wrote:New builds are on my site as well.

Any chance for a Crafty 22.4 build which is still working on old systems (Windows 98) and CPUs (Celeron)?Peter Skinner wrote:New builds are on my site as well.

Even with new compilers this should only be a thing of setting some switches (like Win98-compatible, no SSE2/3 instructions ...).

Re: Crafty 22.4 is now available
This is the reason I stopped offering executables years ago. There are so many architectures. And everyone wants the fastest version they can get for their specific machine. And intel has indeed given us a _lot_ of architectural variance over the years. The number might well be up to near 100 possible different executables today...F.Huber wrote:Any chance for a Crafty 22.4 build which is still working on old systems (Windows 98) and CPUs (Celeron)?Peter Skinner wrote:New builds are on my site as well.

You would really do far better to get a good C compiler, learn how to compile Crafty, then play with the compiler options to produce the best speed you can. Then use that each time a new version comes out and you will always have the best that can be...

Franz,
Every person needs to be given the opportunity to test this engine. Here's the all-purpose Crafty. Just choose which compile is better for you. I did 2 profiling using single and dual-core. I don't know if there's a difference. Anyway, I added a logo for remembrance and good luck
