Spark released

Spark not work with me
maybe the compile vc or ccg w32 not for my xp win
for infomation all versions of bright work well in my pc.

Spark 0.3 is now available:

For some reason Spark 0.3 VC32 is slower than the GCC32 version.

Here is a quick match against the infamous probable clone of Rybka 3.

AMD 3500+ 2.2GHz
Time: 4'+2''
Nunn test match.
No tablebases for both engines.
Hash 256 MB

Code: Select all

1   ***** w32        1½1111½111111111111½   18.5/20  92.5%
2   Spark-0.3 GCC32  0½0000½000000000000½    1.5/20  7.5%

For unknown reasons Spark has hanged twice in the match. So it lost on time. This does not affect the result since the positions was dead lost for it anyway.

Same here for 64bit version

Thanks Allard for the new engine, how does Spark compare to Bright in terms of playing style?

I suppose Bright has the better evaluation (although 'from a different
planet' as some have said), while Spark should be tactically superior.

[Allard Siemelink]

Thanks, Allard !
... I think you forgot to upload Spark 0.1 and Spark 0.2 .
Matthias.

They're both weaker versions, why would you be interested in them?

We want all versions to have better rating lists and good opponent for all Elo ranges. We need Bright 0.1 also.

GCC seems to be stronger than VC. Why is VC slower (Per Readme)? What's different between the two versions?

Different compilers: the gcc versions are compiled by gcc 4.x compilers, the vc versions are compiled by Visual C++ 2008 Express.

On my own setup (AMD/Opteron), the gcc32 version is 10% faster than the vc32 version, but it may be different on some Intel CPU's.
The 64-bit Windows versions were given a quick test by Olivier Deville, performing roughly equally on an AMD/Opteron. But one of these might be quicker on Intel.

You should use the version that is fastest on your machine.

I'd be interested to hear if anyone gets a significant difference in nps for the 64-bit versions.

Here is a logo if you want to use it ...

Thanks!

You'll need a (relatively) modern cpu that supports SSE2, is this the case?

That's good ted but can the spark lettering be in a lighter blue - i find it a bit difficult to see
