Therefore processor p 1 executes iterations f1; 2; 3; 4g. The ON clause is a feature borrowed from the language Kali [25]. 3.1.3 HPF The High Performance Fortran (HPF) [6, 26, 27] language was designed as a set of extensions and modifications to Fortran 90 to support data parallel programming. The ability to achieve top performance on MIMD and SIMD computers with nonuniform memory access was one of the main goals of the project. The design of HPF was influenced by Fortran D and Vienna Fortran [28, 29]. Just as Fortran D approaches the problem of data partitioning and distribution in two stages, HPF uses three. First, arrays are aligned to each other. Second, arrays are distributed across a user-defined rectilinear arrangement of abstract processo...
