(IDC), provides an in-depth look at the state of the HPF language and its impact on the evolving HPC market. Reserve your free copy of this report to learn more about HPF and what it means to your organization. What Is HPF? High Performance Fortran (HPF), a parallel variant of Fortran, is emerging as a common high-level parallel programming model across all types of technical computing systems. HPF encompasses all of Fortran 90, the parallel processing features from Fortran 95, and a simple means to express data distribution among processors in a parallel system. Unlike MPI or threads-based programming, HPF allows the user to write parallel applications at a high level and eliminates the need to directly manage the interaction of the processors in a parallel system. NAS Benchmarks with HPF At Supercomputing '96, NASA Ames released the first official HPF results on several of the NAS Parallel benchmarks. On some of these key benchmarks, the HPF timing results are within 30% of the speed of the MPI implementations. These results provide clear evidence of the continued rapid advancement of HPF technology. With the advent of high-speed globally addressable systems such as the CRAY T3E (tm), SGI Origin (tm), and Hewlett-Packard Exemplar (tm), the need for a standard, efficient, scalable shared-memory programming model such as that provided by HPF has become even more acute. IDC Bulletin Authored by High Performance Computing analyst Christopher Willard, "Technology Update: High Performance Fortran" outlines some of the key features of HPF, its strengths and weaknesses, and experiences related by early adopters of the language. Dr. Willard concludes in part that "The availability of effective compiler tools such as HPF can reduce the need for special staff to program parallel computers and reduce the time scientists and engineers must spend away from their primary responsibilities in order to get programs running."
