Tablebases - Generating them vs Downloading

[Dark Horse]

I read that it is possible to generate tablebases, is this a better option than downloading them ?

If you have a 64-bit system and lots of memory.

4-men tablebases are together 30 MB only. Easy download. (20...30 Elo)
Switching to 5-men (7.5 GB) gives only an extra 10...15 Elo.
6-men are not worth the terabytes space they occupy.

For strong engines, take lower end of mentioned Elo ranges.
For weak engines, take upper end of mentioned Elo ranges.

I use 4-men.

yeah I have 4 man too, if I figure out eMule I might download 5 man, is there anyway you can download the incremental 5 man tablebase if you already have 4 man TBs ?

and Thanks a ton for all the help guys!!!

I have a copy of the TBGen program (WIN exe) that generates the 3 to 5 man tables. If you want to generate them, PM me your e-mail address and I'll mail it to you.

The most important 6-man TB's are not anywhere near a terabyte in size. You can fit key 6man's into 25-50gb on your harddrive, I think the 12DVD version of the Gold Nalimov's takes up 100gb of space on your Hard drive.

it is better surely downloading them, rather than to produced them.
Exclusively for a matter of time.
You have to know that to produce the tablebase 5men KRPKRs, I have employed 7/8 h, with a Core2duo and 1 Gb ram, XP 64 bit.
When I had only the Pentium 4 HT and 512Mb of ram, XP 32 bit, have employed 2 days!
When I had only Celeron and 256Mb have employed 8 days!!

Download it in a few minutes. Nobody could otherwise recommend you

How about keeping the tables at some large server, and download only the moves for the current position?
After all, once you are in an endgametable position, you don't need to search very much, so 0,3s downloading moves won't be so bad?
