Subject: Crafty profile on fast P3/P4/AMD/SMP compiled with gcc, MSVC,Intel C++

Hello everyone!

I have not posted here in a while, because of all the work, but here goes.

I am currently working on a research paper that compares the performance of
various processors combined with various compilers - in particular, I am
attempting to identify the weaker areas of each chip and compiler as related to
bit-board-based chess programs.

I would like to use many detailed "profiles" of Crafty (gproff, MSVC performance
analyzer, NuMega, etc.) to get an idea of different areas in which these
compilers and chips over/underperform. That's where I need help - I don't really
have access to any modern computer (I just have a 450 MHz PII), and I know that
people on this site must have done profiles of Crafty (or can do them), so if
you could post some of them here, I would really appreciate that.

To be more precise, the best profile would come from running Crafty from an
initial position to a certain depth OR solving an EPD. To emphasize, I do not
just want the kNPS for the program, I actually want a detailed profile of the
run - which functions where called how many times and how much % of total
running time did they take (or some analogue of that). The most valuable results
would be those comparing something like gcc results with results of MSVC, but
others are also very appreciated.

I appreciate ALL the help in advance - I think that once we compare these
results, it will point to specific weaknesses of each compiler and architecture
and hopefully help us build better compilers + chips.

Thanks.

Artem

P.S. If you are reluctant to post a large profile on-line please feel free to
just e-mail it to me (pyatakov@princeton.edu)
