RESUMO
We describe the service architecture of the successful TeraGyroid experiment. In particular we discuss the use of the open Grid service infrastructure (OGSI) to build the services used during the experiment and illustrate the problems we encountered.

Computational steering refers to the real-time interaction of a scientist with their running simulation code. Despite the many benefits associated with computational steering, its uptake to date has been limited. In this paper we discuss the reasons for this and how the computational steering library and associated tools developed as part of the RealityGrid project aim to tackle them. We describe the functionality of the steering library and the use of Grid services in constructing a generic, dynamic architecture for discovering, steering and connecting visualization software to running simulations. The use of on-line visualization for providing feedback to the scientist is described, including the ways in which it may be enhanced through tools such as Chromium and Access Grid. Finally, we illustrate the flexibility of our approach by describing the functionality that has been added to various simulation codes as part of the RealityGrid project.

As they did when they were formed 150 years ago, the professions must again convince the public and a cost-conscious and competition-orientated Government that they should be entrusted with the provision of services their training has made them fit to offer. This article explains why.

The European Economic Community was one of the major concerns of the later years of the late Campbell MacKellar. Besides being deeply involved in the affairs of the UEVP--the body representing the practising arm of the veterinary profession in Europe--he was one of the United Kingdom's representatives on the Federation of Veterinarians of the EEC over a period which saw that body emerge into an active pressure group with a real contribution to make to veterinary affairs within the Community. So said Alastair Porter in his introduction to the first MacKellar Memorial Lecture, which he gave last autumn. The following article is abridged from Mr Porter's address.
