Testing new compiles of Stockfish.

Gary, this is the answer I have received from Quocvuong:

Source is being used in Stockfish 120321: I get from Github Wednesday, ‎March ‎21, ‎2012, Link download (Marco Costalba):

Great, thanks Tom. Just wondering if the undefended pieces change was in there, and v1 of it was.

The Intel version seems weak, although its speed is not bad. However the AMD version has shown a relevant strength in this test. (Please note that my computers are not AMD but INTEL).

I was surprised by the performance of Stockfish 120331 PeterPan (Izak) with 6 real cores (+ 2 HT) and I decided to repeat the test. Here you have the results:

Critter, Houdini, Deep Rybka 6 real cores - NO HT
Stockfish120331 AMD 6 real cores + 2 HT

http://www.mediafire.com/?sm3m8vj19cpfnyr

Previous match under the same conditions (AMD compile):

Stockfish 120331P8Amd - Critter 1.4a 64-bit SSE4(x6) 21.0 - 19.0 +11/=20/-9 52.50%

http://www.mediafire.com/?nwfcsilebo9scbf

If we add the previous match I did under these conditions, we have that

AFTER 240 GAMES THE GLOBAL RESULT IS:

Stockfish 120331P8Amd - Critter 1.4a 64-bit SSE4(x6) 41.5 – 38.5 +20/=43/-17 51.87%
Stockfish 120331P8Amd - Deep Rybka 4.1 SSE42 x64 (x6) 44.5 – 35.5 +22/=45/-13 55.62%
Stockfish 120331P8Amd - Houdini 2.0c Pro x64(x6) 36.5 – 43.5 +14/=45/-22 45.62%

AVERAGE GLOBAL RESULT: 51.04%

I know that 240 games are not enough to prove anything, but this is the strongest version of Stockfish I have tested till now. Please note that:

- The INTEL version seems to be much weaker (although my computers are INTEL based!)
- I have added a bit of ‘doping’ with two HT cores. Although Houdini and Critter do not benefit from HT, both Stockfish and Ivanhoe play slightly better with them.
- I would appreciate if testers with very fast machines can work on this AMD version to confirm these results or not. Thanks in advance.

Regards from Barcelona.

Thanks for posting this very good test, Tom. It confirms my previous results. This is one of the best compiles of Stockfish ever. Thanks to Marco & Team for developing Stockfish and also to Izak for this strong compile.

[ernest]

Thanks for posting this very good test, Tom.

On my Core 2 duo, I could not test the popcount versions.
So all I could do, is run the normal mingw compile Stockfish 120331M x64

And that one seems only on par (no better) with my "official" stockfish-222-64-ja-intel...
