Introducing Octochess

[Adam Hair]

I have to say, Jack is one handsome fellow.

Hehe, and in good company. Beware to William, he bites!

CHOMP!

I tried running your Windows compile on my non-SSE 4.2 x64 system, and it didn't seem to work. I guess it's a compile that would need a CPU with POPCNT support?

Yes, Octochess makes use of the POPCNT instruction through the __popcnt64 intrinsic. SSE 4.2 shouldn't be required though, it's a different CPU feature. I'll see if I can create a build that works without POPCNT.

If your program has an account at ICC, you are welcome to match it against my program Symbolic -- it's back after a five month hiatus.

Unfortunately I don't have an account at ICC. I do not plan to sign up for another subscription service at this point.

Wait, what, the FileZilla guy made a chess engine? Cool! Thank you for the new engine, Tim.

I was surprised when I read the fileziila comment, so thanks for both programs Tim.

It's always good news to hear about new engines, and imho even more if they're GPL licensed.

Cheers

You could get a FICS account for free, although you first must perform an elaborate song and dance to receive an approval of a program player.

Symbolic has a FICS account, but is currently inactive there. This will change at some point, but not right away.

My CPU, in a low end 64 bit laptop, supports neither POPCNT nor SSE 4.2. Thanks for the offer of a new compile, Tim, but you don't have to go out of your way to make something special for me.

Ok, I will

I don't think this will run on any Os earlier than Vista. I saw some Vista/Win7 api-specific calls in the source.

Many thanks for the release of your engine Tim.

Jim.

Thank you, Jim.

Thank you Jim. I've added an #if around the non-native popcount and applied your changes to the repository.

64 bit Linux build.
