Subject: intel C compiler (Which VC++ compiler options give fast chess engines? )

hi,

i got the intel C compiler from www.intel.com (41MB download, free, but limited
to 30 days of testing). After running the installation program you can use the
intel compiler instead of the microsoft compiler with one click in the visual C
IDE. it seems to have more optimization options than the microsoft compiler.

i used it to compile my checkers program, but it made about the same kN/s with
the same compile options. i also tried to use some advanced options (profile
guided optimization), then i got about 5% more kN/s but the program crashed very
often :-(

does anyone else here have some experience with the intel compiler? are these
numbers realistic? is my 5% result the best you can get, or is it too little?
i'm running on a AMD Athlon K7 - does it matter that this is a
non-intel-processor? or are the optimizations the compiler makes for intel
processors also beneficial for AMD processors?

cheers
  martin
