7-men Syzygy attempt

[noobpwnftw]

All 5v2 pawnful tables are now built.

How much do they take? The fttp link in the first post gives me 630 files at about one giga per file.

Code: Select all

151G    ./3-6men
3.2T    ./7men_testing/4v3_pawnful         (ongloing)
2.4T    ./7men_testing/4v3_pawnless
2.3T    ./7men_testing/5v2_pawnful
660G    ./7men_testing/5v2_pawnless
117G    ./7men_testing/6v1_pawnful
87G     ./7men_testing/6v1_pawnless

And the first post link is still valid? I'm getting 333 items for 4v3_pawnful (less than 450GB).

The link is valid, item numbers looks correct but not the size.

I know, I tried to download one of the smaller ones, to see if the actual size differs from the reported one, but there's no progress downloading. Also, upon trying to stop it, it froze and I had to perform a hard reboot. I'm logged in as guest.

You can try the mirrors or use an FTP tool to download them.

The out-of-the-box Mac tool was obviously being creative (and lazy):

My estimation was just wild extrapolation. People talked about 10 TB for WDL, and for the current generated 7-man TBs, DTZ files are about 2.6x the size of WDL.

The pawn tables will probably take the ratio down.

The current ratio for the built 4v3 tables is 1.203, so indeed.

I guess we are still hovering around the 20 TB mark for the total estimate, at least based on some very quick extrapolation.

What I'm really wondering, is how big the SSD I place in front of the mechanical HDD will have to be. For 6-men, I use a 256MB drive, which has plenty of room to spare for the cache, even after housing the WDL tables. For 7-men, I'm guessing you'd need something closer to 2TB, rather than 1TB.

You don't need cache for the DTZ tables; they're only looked up at the root, ie., nearly never.

With tables like KQBPvKQR.rtbw and KQNPvKQR.rtbw close to 100GB each, I fear the cache will fill up to unprecedented levels, as soon as we begin to add the ones with Rook(s) and Pawn(s).
