Houdini 1.5 available now !

Houdini 1.5 (20101215): Improved search and evaluation. Gaviota Table Base Support.



The package contains Houdini_15_w32.exe for 32-bit Windows (up to 4 cores)

and Houdini_15_x64.exe for 64-bit Windows (up to 8 cores).

Each executable contains code for optimal execution from single-core up

to the maximum number of cores.

On a 64-bit platform the 64-bit version is about 30% faster than the 32-bit version.

If your hardware supports SSE4.2

the program will use the POPCNT instruction for another slight performance gain.

2 Deep Rybka 4 w32 +12/=63/-55 33.46% 43.5/130

woooooooooooow!!!! finally another update of houdini. Thanks for the info. been out for a while from vacation. im glad to be back.

There is no doubt that houdini is the strongest engine in the world. Look at these test results by halestorm:

Code:

1  Houdini 1.5 x64                  +61  +12/=23/-5 58.75%  23.5/40
2  Houdini 1.03a x64 POPCNT 4_CP  -61  +5/=23/-12 41.25%  16.5/40

I will run some tests later.

Is anyone else concluding that Houdini 1.5 x32 is stronger than Houdini 1.5 x64? I have seen several test results online showing this.

is the 32 bit version better?

Interesting to test it ourselves. I will try to verify it tonight. thanks for pointing it out

Can't wait to run the test myself.

so i started right away. here's some initial snapshots of the KN/S of each engines:





There seems to be a substantial difference in kn/s speeds between the two versions. will post the final results later in the engine testing room.

Houdini 1.5 w64 vs Houdini 1.5 w32 test now completed.
