PROGRAMMING MODELS AND LANGUAGES FOR HIGH-PRODUCTIVITY COMPUTING SYSTEMS* HANS P. gov High performance computing (HPC) provides the superior computational capability required for dramatic advances in key areas of science and engineering such as DNA analysis, drug design, or structural engineering. Over the past decade, progress in this area has been threatened by technology problems that pose serious challenges for continued advances in this field. One of the most important problems has been the lack of adequate language and tool support for programming HPC architectures.
