Is the torrent still active? If so shouldn't be to hard to get it added to the system.

Re: Can we add this .torrent file to Olympuschess tracker ?

I will do my best to see about hosting this. I've been tempted to host this set (and I do I have the full set) but due to its enormous size was concerned about seeds.

Will update once I figure out an answer.

Would a public snail mail swap still be something of interest? Say use this forum, and make the request. I load it up and send to the first person...

Re: 6 piece scorpio bases

Side topic, but I host the 3-4-5 scorpio bitbases on my site. Someone told me they were no longer useful, because as of the most recent version of scorpio the format has changed, so I would need to regenerate them for the latest version. Is this true? If so I'll remove the version I have. Willing to...

Giving this app another try. Now that I have a Windows-64bit machine with 8gigs of RAM. My last attempt was via wine and didn't fair so well.

Seems like a promising project.

Re: Generator of 3-4-5-6-7-chessman tablebases. Version 4.

Took a look at the site but the download button doesn't yield anything.

If it really generates 3-7 then this is amazing. Looking at the html didn't yield anything though in terms of a download, system requirements, etc.

Re: 7-man EGTB Bounty Reborn - General Discussion

I agree the generator and example probing code should be in C. It's robust, fast, and you can pretty much write a wrapper in any other language. If I may suggest, I think the file format should be one of the first things that needs tackled. Because even if we can get a hodge podge generator running ...

When you rewrite the 5 man and generalize it for larger counts, how about making it totally general so that 7,8,9 etc. man files can also be generated.

Gaviota and 6-men

When Gaviota was released there was a lot of discussion on how to do the egtb generator (that ultimately was for the benefit of 6men).

Wondering if there has been work on that since or if it was still a goal? Then perhaps even 7-men.
Hope everyone is well :)

Not familiar with par but will check it out.

I have 3-4-5 stored on 3 different drives, some 6men duplicated but most of my 6men are on just 1 large drive. So I hope it never dies lol. Drives are getting cheaper though so might pick one up on a good sell day for duplication.

7-Men and fast Hard drives

A while back I was reading about an egtb generator that mentioned the possibility of 7-men, but do to the intense memory usage it would require swapping to to disk. (Muller perhaps?). Came across this today and thought maybe this would help with such a bottleneck. http://www.physorg.com/news18543812...

Gaviota 3-4-5 Soon available

I finished generating the 3-4-5men set for the gaviota engine/egtb's. It will probably take about 12 hours or more to upload to my site but they will be stored there. Included is a sha1sum and md5sum of the files but the authors tbcheck also works wonderfully. http://olympuschess.com/egtb/gaviota/ T...
