Spark released

[Mike S.]

In Windows Vista 32-bit and with a Pentium D945 cpu, the gcc32 version seems a little bit faster, but the difference is very small:

Thanks for testing.
I guess there is no need to release future 'vc32' versions then.

Any chance for a linux 32 bit Spark???

[Leto]

Doing some testing for this engine for the CEGT Blitz list, it scored 51% against Loop 13.6 x64 4CPU in 50 games.

[Vinvin]

1 thread vs 4, great result. Loop 13.6 x64 4CPU is about the same strength as Deep Sjeng WC 2008 64-bit (1CPU) !

Scored 40% in 50 games against Deep Fritz 11 1CPU.

Scored 66% against Fruit 2.2.1 (2767) in 50 games. I suspect Spark 0.3 x64 is around 2850 CEGT Blitz elo.

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

I like yours better, but here's an alternative if anybody would like one.

I have to agree. I'm running a 1400 game gauntlet at this moment,
and the results so far are impressive.
