I got a chance to recompile the 64 bit Crafties with the new compiler that has optimizations for AMD64 and EM64T chips. No idea if you will see an increase in speed as I do not have access to either of them.

Enjoy!

Will there be an amd64bit verison with smp of the new cito?
Also is it possible to compile an smp for up to 8cpu?
Wondering if the bscale option could be turned back on, and I have read before that someone was experiencing problems that when an someone resigned on ICC, crafty would logg out. Although, this is much better it does happen from time to time.
Thanks these complies are fantastic!!!

Sure I can do the 64bit compiles of Cito, I will try to get them on line this weekend. I can compile for 8 CPUs if need be, but who would need such a compile? Do you need a 8 CPU compile for windows, if so let me know and I will create one. As for the resign problem, that was due to the SSE/SSE2 compiler flags which I do not use now.

Glad you enjoy the compiles and thank you.

Hi Bryan,
I tried to download Crafty Cito for a single cpu several times,but it keeps giving me a server failure
Any ideas about the reason for this....

I have no idea, as I just went to the page and downloaded the file. If you send me a private message with your email address, I will mail it to you.

bryan thanks for the quick response. I have a quad 870 dual core on order so yes 8-way would be great for cito and crafty in 64bit of course. thanks

This is a $15,000.00 system (bare bone) for chess??????

Ok, I have updated the SMP compiles for Crafty to 8 CPUs and added 64 Bit compiles for Crafty Cito.

Hi Bryan,
I have sent you an e-mail requesting the Crafty Cito 1.2 single CPU version, futility pruning turned on
I hope that you can send it to me....it's impossible to download it from your site from my system

On it's way...

Hi Bryan,
Thank you for your understanding

thanks bryan that was fast. One question is that under the bench for cito I got 3.6mill per sec and with crafty 19.19 I got 4.1 mill per sec. Is this right that cito is slower than crafty but may play stronger. Oh well I will test it for a couple of days under my ICC account if you are a member I can tell you my account so look at some of cito64bit games under my history! Thanks again.

You really can't compare Cito to Crafty in NPS as I am doing much more aggressive pruning (thus it searches less nodes). What should be a comparison is the time of the benchmark. Since the bencmark does a eval on the same positions to the same depth. You should see that Cito is able to do the bench faster in time.

Which compiler are you using and where did you get it? From my perusal of Microsoft's webpage, it looked like you had to get Visual Studio Professional to get a 64-bit compiler.
