NEW supercomputers are adding daily to aerodynamics research tools. These computers have made possible a relatively new field of aerodynamics research, called computational aero‐dynamics.

A general philosophy is presented in which all the modules within the computational cycle are parallelised and executed on parallel computer hardware, thereby avoiding the creation of computational bottlenecks. In particular, unstructured mesh generation with adaptation, computational fluid dynamics and computational electromagnetic solvers and the visualisation of grid and solution data are all performed in parallel. In addition, all these modules are embedded within a parallel problem solving environment. This paper will provide an overview of these developments. In particular, details of the parallel mesh generator, which has been used to generate meshes in excess of 100 million elements, will be given. A brief overview will be presented of the approach used to parallelise the solvers and how large data sets are interrogated and visualised on distributed computer platforms. Details of the parallel adaptation algorithm will be presented. These parallel component modules are linked using CORBA communication to provide an integrated parallel approach for large scale simulations. Several examples are given of the approach applied to the simulation of large aerospace calculations in the field of aerodynamics and electromagnetics.

The purpose of this paper is to review some applications of supercomputers, with the observation that a readily available PlayStation can rival supercomputers of a decade ago. Applications to ocean modelling and to examination of possibilities for quantum computing are discussed. Also discussed are the meaning of the term Wiki, and uses of Wikis in language learning.

The aim is to review developments on the internet, especially those of general cybernetic interest.

Supercomputers have valuable applications in biological modelling, medical record keeping and climatic studies and there is particular interest in their use to explore possibilities of quantum computing which may be the key to more powerful machines of the future. The value of Wikis is not confined to the Wikipedia.

PlayStations are likely to be taken seriously as programmable computers in certain areas. Possibilities for a new generation of quantum computers are discussed, as is also the use of Wikis in language learning.

It is hoped this is a valuable periodic review.

This paper details advances in biocybernetics and gives reports and surveys of selected research and development in systems and cybernetics. They include supercomputers, biometric technology, formal methods, applications of nanotechnology, innovations, and cybercriminals.
