Pfortran
Babak Bagheri, Terry W. Clark, L. Ridgeway Scott · ACM SIGPLAN Fortran Forum · 1992
IPfortran is a language designed to facilitate the programming of multi-process, data-parallel applications [BCS91]. Based on a message-passing paradigm, IPfortran extends Fortran with a small set of extensions. The duality of the send and receive operations is encapsulated in an infix operator (Section 2) or reducing functions (Section 3). With system-dependent message-passing pushed out of sight, code is streamlined and development time reduced. Errors in writing message-passing code are reduced by leaving the generation of the message-passing logic to the translator.
