Very good. Note, however, that if optimization is important to you, you will
find commercial compilers better in that respect (I get a factor of 2
between g95 and CVF).

Re: Differance between Fortran 90 and C ... And as for g95: I gather, it's very strict to the standard, and there's some weird standard-adhering code which compiles *only* with g95, but small chance you're going to use such features :-) But on the other side, its optimization features are rather weak and the code produced is rather slow. ... The Intel compiler took about the same time without any optimization.... There's no doubt you could write code for g95 which is about as fast as the one produced by the Intel compiler, but it's going to be a lot of work. ... So, if you're not earning money with your code and are going for Fortran, I suggest you go to the Intel homepage and download the free non-commercial version of the Fortran compiler (and perhaps also the ...
