In the long history of high-performance computing (HPC), few tools have commanded as much respect in scientific and engineering circles as the Intel Fortran Compiler. While the software industry constantly churns toward the new and the now, certain versions achieve a "legendary" status—not necessarily for being the newest, but for being the most stable, the most compatible, or the perfect bridge between legacy code and modern hardware.
