Thread: Mac OS X Users/C programmers?

compiled with gcc -o test test.c -lm

Code:

execution time for integral = 15.98 seconds
execution time for prime = 19.25 seconds
execution time for Goldbach = 53.5 seconds
execution time for dynamicfnc = 5.45 seconds
total execution time = 94.18 seconds
sh: line 1: PAUSE: command not found

This is a linux box(gentoo) 1.01ghz with 512mg of ram
compiled with gcc -O3 -march=pentium3 -pipe

Code:

execution time for integral = 14.76 seconds
execution time for prime = 18.54 seconds
execution time for Goldbach = 48.64 seconds
execution time for dynamicfnc = 5.37 seconds
total execution time = 87.31 seconds
sh: line 1: PAUSE: command not found

Okay, the thread is quite old, but I thought it might be interesting to see what this little proggie might do on a more modern iMac8,1 with a 3.06 GHz Core 2 Duo. Program compiled with "gcc -O3 bench.c -o bench" (removed the system function call):

Code:

$ gcc -O3 bench.c -o bench
$ ./bench
execution time for integral = 1e-06 seconds
execution time for prime = 1.73697 seconds
execution time for Goldbach = 6.28933 seconds
execution time for dynamicfnc = 0.605303 seconds
total execution time = 8.63174 seconds
