6 piece EGTB

[vb4]

There has not been much conversation on this subject and I was curious if any of you out here knows of anyone who has completed the set of 5-1 EGTB's. My interest is in the stat files and not the actual tablebase files themselves. I understand there are 32 of these tables and I think someone had mentioned they generated 16 of the 32 remaining ones which means only 16 remaining. Does anyone here know of anyone who has completed the remaining 16 tables or has a generator that can generate them without code modification? I am studying the 3-4-5-6 piece EGTB's and need to have completed sets to finish my work. Any help or guidance would be deeply appreciated.

What would be the approx. size of all 6-men TB? (or even 7 men, if anyone wants to guess)

The whole set of 6 man EGTBs would require 1.2 Terabytes of spae. They can all be downloaded from here:

Regarding generator this may be of interest:

Thanks for the info, mark. I am going to buy a system with 140gb memory now (I kid, I kid). I don't think the 7-men tb will be made any time soon - not because we won't have the resources to create the tablebases, but who will download supposedly several 100s of terabytes worth of TB and where will they save them?

Hard disk is about $100/TB now.

Fast Ram is about $40/GB or $40,000/TB.

If IBM were to build Deepest Blue today, I am pretty sure they would go ahead and load them all into RAM. The millions of dollars spent would be recoverable, anyway.

Now, as to "the rest of us"...
In six years, hard disk will be less than $2/TB and RAM will be about $600/TB.

Even today, $2000 worth of disk will get you 20 TB and $2000 worth of RAM will get you 50 GB. So a serious hobbyist with plenty of cash can build a realistic system for access of the full 7 man TB files today.

And in less than one decade, all of us will be able to do that. And we will instead be puzzling about the 8-man files.
