My understanding is that it's primarily sparse matrices which Fortran is
best suited to. Try modelling a 1 million cubed array in C++ with only
a tiny fraction of the space occupied and see how it likes it ;-)
As Bobb said, the code for huge amounts of Stuff is already written and
out there in Fortran and in use, and until it's easier for those using
the code to use something else, they will continue to do so.
