Komodo 3 release

[lkaufman]

The basic style hasn't changed, but we determined that Komodo 2 was too materialistic so we made it somewhat more willing to give up a pawn for positional compensation.

We are working on the next Komodo release now.

Already available are Komodo 3 for Android and Komodo 3 for 64 bit Linux. Hopefully we will have Komodo 3 for windows in the next day or two.

We believe we have approximately 30 ELO of improvement and more at non-fischer time controls which we were deficient in. However it's difficult to say for sure how much we have gained as this depends on how it scales to time controls we don't test at.

The majority of the gain has come from evaluation improvements.

Thanks Don,

I see the Windows 64bit version has been released. Bad news is I can't get it to run on my system. Crashes on install.

Both komodo-3.exe and komodo-3-sse4.exe crash immediately under my Windows 7 64-bit

thanks Larry for this additional precision about Komodo's changes

I am not able to easily verify the binaries - but I suspect that it's a platform issue of some kind because it did work on the developer machine.

I will look into it shortly ...

Whereas komodo-203-64-ja.exe has worked fine on my Sabayon/Wine/Aquarium system, I'm afraid neither of the new komodo64-3-win engines do.

One minor point. I don't know whether somewhere you've acknowledged the people who helped you test Komodo (of whom I was the least).

same here under my vista 64 bit.

Core i7: both executables are working
AMD Phenom II: both crash

Seems like misconfigured compiler options. Both compiles do contain SSE4 instructions, they crash with an 'illegal instruction' exception. The offending opcode is pmovsxdq which is indeed SSE4 one.

hope this helps.


PS: I would much appreciate a Win32 version too if it is possible.

Both crashes here too. Win 7 - Athlon II

I depend on someone else to make the compiles for me so it's very difficult for me to work through the issues. But I am trying ...

We will be also producing a win32 version of course - and also 32 bit linux.

I can make my own flawless compiles with a cross compiler, but the binaries are inferior and I'm afraid people will start testing with them.
