Introduction to “Nonlinear Problems”

Abstract

The diversity of problems which attract a parallel solution is the theme of the concluding chapter of these proceedings and was strongly apparent in the conference presentations, with some outstanding student contributions. Papers included applications as varied as the study of the astrophysical N-body problem, parallel grid manipulation in Earth science calculations, simulations of magnetised plasma and sensitive use of techniques required for a range of industrial problems. A number also considered general questions of algorithm design, coding features and cost implications for implementation. Efficiency and scalability of the developed code, on a variety of parallel platforms, were discussed by several authors and performance analyses provided. Parallelisation strategies were evaluated in the context of architecture availability for portability, speed and communication features.
