An overview of High Performance Fortran

Since its introduction over three decades ago, Fortran has been the language of choice for scientific programming for sequential computers. Exploiting the full capability of modern architectures, however, increasingly requires more information than ordinary Fortran 77 or Fortran 90 programs provide. This information applies to such areas as• Opportunities for parallel execution• Type of available parallelism - MIMD, SIMD, or some combination• Allocation of data among individual processor memories• Placement of data within a single processor
