High Performance FORTRAN

HPF or High Performance Fortran is a collective set of extensions to Fortran 90 with structures that support parallel computing. It is published and supported by HPFF, a coalition of industry, laboratory and academe representatives that work on HPF. HPF uses data parallel computation to support a single array’s computation to spread over multiple processors. This enables efficient application for MIMD and SIMD architectures. HPF features compiler directives for distributions recommended for array data, additional library routines that include parallel suffix/prefix, environmental inquiry, sorting operations and data scattering, extrinsic procedure interfacing to non-HPF parallel procedures like message passing, and new Fortran statements like FORALL and ability to make PURE [side-effect free] procedures.
