Linguistic Support for Heterogeneous Parallel Processing: A Survey and an Approach

Coding a highly parallel application to run on a heterogeneous suite of processors (both metacomputers and mixed-mode computers) with high efficiency, ease of implementation, and portability is a significant challenge. This paper first surveys recently proposed and existing parallel languages from the perspective of programming complex, heterogeneous systems. We then propose two essential features to be included in programming languages that are intended to support heterogeneity. * 1. Introduction Recent examples have shown the success of combining heterogeneous computing hardware to solve complex problems[1, 2]. When the architecture of the machine matches the structure of the problem, the algorithmic solution is often easier to develop and can execute more efficiently. The currently popular practice of networking existing machines is merely a beginning [3]. As hardware continues to diminish in size and cost, new possibilities are being created for systems that are heterogeneous by..
