Do you have bzip2 (free)?
If not, do you have 7-zip (free)?
If not, do you have PowerArchiver (commercial)?

I guess that you are trying to open it with the wrong tool.
Hi Dann,
I have PowerArchiver (commercial) and whne I open it and mark the file it shows size ? and when pressing the Extract File button it doesn't do anything....

Thanks Dann!

I also uploaded it to the gaviota web site.

Wael,
This version is 0.74.6 rather than 0.74.8. The difference is very small, related to how EGTBs are generated. If you do not generate them, they are identical.

PS: if it works well, I may include the utility tbcheck in the distribution or I may integrate it to the engine.
I ran it on my tablebases just to double-check, and all were ok
I would include as a separate exe in the distribution

A more general question: how big are all 5-men egtbs? I'm running the program around two days now. I got 117 files generated so far and around 23 GB are used. That seems a bit much to me.

Wouldn't it be possible to spread a verified set of tbs via emule or a torrent?

Regards

145 files and 38GB in total

Yes, emule or torrent would be a good idea

Hello Miguel!

Great to see your EGTB Generator is working! It would be really interesting to me if you could explain some of the details like indexing used or generation algoritm. I just tried to figure out the indexing myself but wasn't able to fully grasp it.

What I got, it uses the trick to index Kings separatly - 462 positions for pawnless. But doesn't take into account the fact that 2 pieces may not stand on the same square. Furthermore both tables (wtm, btm) are integrated into one file.

But I didn't get the way the pieces are indexed. So for example the KRK file starts with: "0x0303 0309 0909 0909 0309 0909 0909 0909" this sequence seems odd, because I would have expected it to start with a broken position as the rook is standing on the same square as one of the kings and even if broken positions are not marked I don't quite understand the following values.

Thanks in advance,
Edmund

38 GB for full set, they are not compressed.
I am negotiating with Miguel on a compression scheme. The compressed files would be about 3.8 GB.

The advantage of them being uncompressed would be much faster access by the engine, would it not ?
