If she's a student, she can download the intel fortran compilers(I'm
talking about the commandline compilers, not the visual) for free. They
have a number of dev libs that are useful too.
I've had grad students and profs in the past get good results using
Matlab, intel and the intel MKL.

gfortran is a vast improvement on g77. On the commercial front, all my
experience is with the stuff from Portland Group, which is good.

Do they mean that they support OpenMP? This is hardly remarkable in a
