I was reading alot of the posts lately and I thought I would try the same as others with Crafty. I finally got Crafty to compile correctly after making my own makefile, and well winging it :) Here are the results of both compilers with a non-smp and smp build: Intel 8 SMP Build Initializing multiple threads. System is SMP, not NUMA. EPD Kit revision date: 1996.04.21 unable to open book file [./book.bin]. book is disabled unable to open book file [./books.bin]. Crafty v19.10 (1 cpus) White(1): bench Running benchmark. . . ...... Total nodes: 89942714 Raw nodes per second: 768741 Total elapsed time: 117 SMP time-to-ply measurement: 5.470085 White(1): Intel 8 Non-SMP BUild EPD Kit revision date: 1996.04.21 unable to open book file [./book.bin]. book is disabled unable to open book file [./books.bin]. Crafty v19.10 White(1): bench Running benchmark. . . ...... Total nodes: 89942714 Raw nodes per second: 768741 Total elapsed time: 117 SMP time-to-ply measurement: 5.470085 White(1): MSVC 6.0 sp5 Non-SMP Build EPD Kit revision date: 1996.04.21 unable to open book file [./book.bin]. book is disabled unable to open book file [./books.bin]. Crafty v19.10 White(1): bench Running benchmark. . . ...... Total nodes: 89942714 Raw nodes per second: 686585 Total elapsed time: 131 SMP time-to-ply measurement: 4.885496 White(1): MSVC 6.0 sp5 SMP Build Initializing multiple threads.

Crafty v19.10 (1 cpus) White(1): bench Running benchmark. . . ...... Total nodes: 89942714 Raw nodes per second: 691867 Total elapsed time: 130 SMP time-to-ply measurement: 4.923077 White(1): Obviously the Intel 8 compiler won. The Intel 8 compile was 12% faster than the MSVC 6.0 non-smp build, and 11% faster than the smp build. That is quite a speed up. I have made all 4 builds available for download for people to test, and possiby post their results. I would like to see a few: http://members.shaw.ca/craftychess/wcrafty-test.zip Peter.
