Subject: Re: INTEL C++ finally faster!!

Go up one level in this thread


First, some time ago *you* wrote that you have to use 2 copies of EGTB cache and
decompression tables because you uses processes, not threads. I would not call
such the design "very professional done".

Second, it took me exactly 15 seconds to find out how you can easily get back
those 10% of the speed in your program.

Third, of course I don't have access to the source of your chess program, but I
can bet that your TB indexing code is exact copy of mine -- and any expert will
say so, too.

And forth, I gave permission to use my TB access code to *anyone* who asked. You
are the only programmer who did not bother her/himself even to ask.

Regards,
Eugene
