In this paper we consider productivity challenges for parallel programmers and explore ways that parallel language design might help improve end-user productivity. We offer a candidate list of desirable qualities for a parallel programming language, and describe how these qualities are addressed in the design of the Chapel language. In doing so, we provide(More)
High Performance Fortran (HPF) is a high-level data-parallel programming system based on Fortran. The effort to standardize HPF began in 1991, at the Supercomputing Conference in Albuquerque, where a group of industry leaders asked Ken Kennedy to lead an effort to produce a common programming language for the emerging class of distributed-memory parallel(More)
Exploiting the full performance potential of distributed memory machines requires a careful distribution of data across the processors. Vienna Fortran is a language extension of Fortran which provides the user with a wide range of facilities for such mapping of data structures. In contrast to current programming practice , programs in Vienna Fortran are(More)

The strong focus of recent high end computing efforts on performance has resulted in a low-level parallel programming paradigm characterized by explicit control over message-passing in the framework of a fragmented programming model. In such a model, object code performance is achieved at the expense of productivity, conciseness, and clarity. This paper(More)
Vienna Fortran, High Performance Fortran (HPF) and other data parallel languages have been introduced to allow the programming of massively parallel distributed-memory machines (DMMP) at a relatively high level of abstraction based on the SPMD paradigm. Their main features include directives to express the distribution of data and computations across the(More)
Data parallel languages, such as High Performance F ortran, can be successfully applied to a wide range of numerical applications. However, many advanced scientic and engineering applications are multidisciplinary and heterogeneous in nature, and thus do not t well into the data parallel paradigm. In this paper we present Opus, a language designed to ll(More)
