Fortran Vs. C (g77 vs GCC) for numerical analyses

Fortran Vs. C (g77 vs GCC) for numerical analyses

[Rodrigo Oliveira]

Hi! I'm a engineering student and I work with
numerical analyses. I'd like to write my code using C
language, but I've noted that g77 has a better
 performance than gcc. And I know that g77 uses gcc to
compile a fortran code. Is there any documentation I
can read to know how to improve the C code (or the
binaries) performance for numerical analysis under
linux?


Thanks very much,

Rodrigo <rdglinux@yahoo.com.br>

I hope you don't mean this, but it's true that most of the options are the same for g77 and gcc.

Depending on your questions, they might be more on topic on comp.lang.fortran, or gcc-help, or might be covered by a google search.
