Objectivies and Approach

The purpose of this project is twofold: to produce tools for the effective utilisation of parallel computers and to develop software for numerically intensive applications. The research will contribute towards the development of suitable techniques and tools for the parallelisation of applications, for parallel programming and management of parallel applications, and, in particular, meteorological computations, environmental analysis and design of scaleable parallel algorithms.

Progress and Results

The results achieved so far include: construction of a performance model for the comparison between the PowerXplorer and MANNA, on-going implementation of the RAMS (Regional Atmospheric Modelling System), design of scaleable parallel algorithms for various problems such as list ranking, tridiagonal linear systems, graph connected components, design of algorithms for cryptography of the type FEAL (fast data encryption algorithm), on-going design of a parallel C compiler for distributed memory machines.

Information Dissemination Activities and/or Exploitation

In November 1995, this project was presented at the FEBRAL "Feira Brasil-Alemanha" (Brazil-Germany Exposition). During the exposition, the DYMOS pollution analysis system was demonstrated using the Parsytec PowerXplorer machine. The exposition was attended by both Brazilian and German officials. In addition to this demonstration, this research group participated in a poster session.
