Intel Visual Fortran Compiler 11.1.051 Professional Edition For Windows -

The Professional Edition distinguished itself with and OpenMP 2.5/3.0 support. This allowed a developer to take a 10,000-line legacy Fortran 77 simulation and, with the addition of simple compiler directives (or even automatic detection of independent loops), run it across all available processor cores. At a time when multi-core processors were becoming standard but parallel programming was still a niche skill, this feature democratized high-performance computing. It allowed domain experts (meteorologists, physicists, biologists) to achieve near-linear speedups without becoming threading experts.
