High Performance Fortran

摘要

Fortran 90 provides ideal language support for data parallelism in the form of concurrent array operations. To achieve high efficiency in a massively parallel environment, however, arrays must be optimally distributed over the processing elements. High Performance Fortran is an extension of Fortran 90 that allows such optimum distributions to be specified in cost-effective and portable manner. This paper briefly describes basic parallel architectures and programming paradigms, and sketches the nature of High Performance Fortran.
