Faking "fast time".. No idea who would want to do that that, but.. Would not loading the entire log, and scaling down the times proportionally pass your validation? :-) Yes, it could :) The reason I made the log file so complicated was to discourage that. You would have to scale the times...

But I wonder if the existing TBGEN for the TB6 generation uses multicore. I can't get it to run at all! It came with a pre-configured file looking to run under 2 cores, so I am wondering what is messing it up? Here is where you can get a 3.9 GHz, 4.0 GHz, or 5.0 GHz system: http://www.liquidnitroge...

I did solve tb7 for checkers with a programming buddy of mine named Gil Dodgen (this was back in 2003) and ...

I have access to some very fast hardware. I am generating the 5-piece tablebase set on my slowest computer right now using these settings: Cache size: 256 MB Memory usage: 571 MB Main memory: 4096 MB I am wondering if anyone knows if these settings are optimal for TB5 generation? (they were filled i...
