0.74.12 FINALLY! solved the problems to build Gaviota tablebases in Windows, with lower memory than 1 Gb, in both 32 and 64 bit systems. Thanks a lot to Gabor, Ray, and Volker who generated them in different systems. (win32, win64, Linux). Thanks to them, the generation for any other user will be very straightforward.
As a consequence of all this testing, I wrote tbcheck, which is an utility that checks if any of the files you generated is corrupted. You want to have this if you decide to generate the TBs.
Dann C. found two problems that were also fixed. In analysis mode now Gaviota ignores the book as it should, and an apparent communication problem with Arena. He also compiled a Win64 version.
If you downloaded any 0.74.xx version and did not experience any of these problems, maybe you can ignore this message
. The strength is exactly the same and you can keep using that version.Regarding TBs, now that the generation is correct the roadmap is
1) build a compressor for the tables (I do not believe is needed for performance but releasing > 30 Gb of the HD of testers will be a good thing)
2) Optimize for speed (generation, compression/decompression, & probing)
3) Probably release the code at this point
4) go for DTZ50
5) go for 6 pieces?
Just for the record v0.74.11 (unreleased) was used in the ACCA tournament using the TBs, who were critical to draw crafty in a BP vs R position with few seconds left in the clock
