--- Quote from: H_TeXMeX_H ---Hmmm ... how do I compile it ? (I know it's a stupid question, but unless it's got a makefile, I have no clue)
--- End quote ---
I was stuck on that too, but made an edumacated guess and got it. All you have to do is type this at the command line (assuming the file is in your PWD)....
--- Code: ---%cc ./benchmark.c
--- End code ---
The the file will be compiled. The resulting binary should be called "a.out".
After that just execute "a.out" to run the benchmark.

Okay, here is my Dual Core 4400+

And here it is, two at the same time... (dual core rocks!)

solemnwarning:
It has the compile command in a comment at the start of the file :\
H_TeXMeX_H:
Thanks for the instructions toadlife ... the "gcc -Wall cpuwars.c cpuwars.o" didn't seem to work ...
here are the results for my laptop's 2.8 Ghz P4 (no HT) ... kinda funny how the floating point is half that of toadlife's AMD, but the pi calculation time is pretty close (4-5 sec).
