Two Fortran compilers are available on both Windows and Linux:
The Intel compiler is more highly optimized and should provide better performance at CTC. More details on all compilers can be found in the workshop modules Compiling and Porting Serial Application for Windows and Compiling and Porting Serial Application for Linux.
Users preferring a free compiler or who have portability issues might choose g77. But in general, Intel is the preferred Fortran compiler at CTC.
