Distributed-memory parallel processors (DMPPs) can deliver peak performance higher than vector supercomputers while promising a better cost-performance ratio. Programming, however, is harder than on traditional vector systems, especially when problem

The machine model considered in this paper is that of a distributed memory parallel processor (DMPP) with a two-dimensional torus topology. Within this framework, the authors study the relationship between the speedup delivered by compiler-paralleliz

While productive use of parallel systems for business applications is quickly growing, their usage for scientific applications is far below expectations. The main reason is that programming of parallel systems is still far too complex. Starting from

Distributed memory parallel processors (DMPPs) have no hardware support for a global address space. However, conventional programs written in a sequential imperative language such as Fortran typically manipulate few, large arrays. The Oxygen compiler
