Hi, I have been running a neural network program (that I compiled using gcc 2.5.8) and I have noticed that the program (while running under Linux) is about 40% slower than the same program (running under DOS and compiled with Turbo C). I have narrowed the possible causes of the poor performance down to the transcendental functions (cos, exp, etc). Does anybody know of a "better" math library or version of gcc, with respect to math performance? Thanks Ron rmarsh@plains.nodak.edu P.S. I can't stay with dos because the size of my training files will create other problems.
