Intel Fortran compiler

The Intel Fortran Compiler, or ifort, is a Fortran compiler developed by Intel and available for Linux, Windows and Mac OS X.

Presently, the compiler has full support for Fortran 95 and partial support for Fortran 2003. Some features of the Fortran 2008 draft are implemented as well. The latest information about standards support is available in an article entitled support for Fortran language standards.

The Intel Fortran compiler is freely available for non-commercial use.
