Gaviota 0.74.6 (special for EGTB builders)

[Miguel A. Ballicora]

Version 0.74.6 =
1) I fixed a bug that prevented Gaviota to be used without logs.
2) Building Gaviota tablebases require much less RAM memory available (< 500 Mb).
3) The default download contains a smaller book, so people can download the engine without problems. If someone wants the bigger book, it is available separately.
4) Everything else is identical to 0.74

For example, to generate the EGTBs start gaviota in the console and type

memory 1
cores 4
tbgen 5

It will reduce the hastables to 1 Mb (not to occupy memory)
will use 4 cores or cpus (if you have a quad)
will generate all the 5 pc TBs in order. If you stop the generation, you can come back later, type the same thing again, and it will continue from where it left.

Do you expect a Linux version in the foreseeable future?

Done!

I just uploaded Linux 32 and 64 bit versions. The book is the same for any version (even Windows) because it is portable.

Thank you! I'm just playing around with the different tablebases. It will take some time until I get results.
First hint for Linux users of your program:

change tb_path_1= "gtb\" to tb_path_1= "gtb/"

Obiviouis but not to obvious to oversee it.

Thanks, good catch.
I fixed it already. I messed it up because I copy and pasted the folders I used from Windows. You can use "gtb" too because the engine automatically adds / or \ depending on the version.

Make sure you are using version 0.74.8. I uploaded 0.74.7 first but I found a bug right after uploading it. I fixed it, and uploaded 0.74.8 but maybe you got the wrong version in the time it took me to do the switch. If you started using 0.74.7, you can stop and start with 0.74.8. It will continue from where the other left.
