with a simple 'bench' you can verify functionality is equivalent. For a guess about speed it is better to test with

Code: Select all

./stockfish bench > /dev/null
so that console output time is not included.

Did you run from starting position ?
I don't mind the speed to much but a "bench" should test speed ... !

Yes from the starting position.

As it is reproducable by others I would say, start a GUI ...

Thx for the Stockfish version regardless of minor problems

Ingo,

If the GCC x64 SSE42 version gives the same PV as the 32-bit version, that is probably the one to use... But perhaps wise to hold off for now. Did you run the 32-bit version as a comparison ?

Hi Ray,

All builds are Gcc/Mingw compiler except normal Windows 64 bit SSE 4.2 which is Intel compiler.
I included the Intel version for AMD compatibility. GCC SSE4.2 compile did not run on AMD Phenom with last release.
It does now so Intel version may not be needed anymore.

Jim.

OK, that is clear now. We should all ignore the normal Windows 64 bit SSE 4.2 Intel compile. Perfect, now I can move forward.

OK, so to summarise, on my AMD Phenom II X6, infinuite analysis from start position, Shredder 12 GUI:

Depth 21/32 (21323761 positions with all the exes below and identical PVs)

32-bit kn/s 950
64-bit generic kn/s 1235
64-bit SSE42 GCC 1276 kn/s

Jim, I think you should remove the Intel SSE42 exe from the distribution.

Hi Marco,

here some numbers from my machine.

JA-Compile 64bit Linux:

Code: Select all

bestmove e2e4 ponder e7e6

JA-Compile 64bit SSE42 Windows:

Code: Select all

my compile (make build ARCH=x86-64-modern) Linux:

Everything looks fine to me.

Many thanks for this new version.
Kind regards,

Hmm... the GCC SSE42 version just crashed under chessgui and chess960. I'll investigate further.

Thanks Joerg,

In case you plan to integrate in Droidfish I'd suggest to set "Use Sleeping Threads" to default to true in ucioption.cpp: it should be much better reagarding power consumption on Android with multicore.
