Abstract

We describe a computing environment that we call a "mini-GRID". This represents a hetereogeneous group of resources for computation, data storage, archival and visualization which can be connected via private or public networks to other resources (called "guest systems") on a temporary basis as required. The mini-GRID displays the heterogeneity and some of the complexity of a full computational GRID, but in a more limited environment and can be considered to be under the control of a few organisations (or even a single organisation) making nontechnical organisational issues less problematic. As such, the mini-GRID provides a flexible and controllable, but realistic test-bed for trialling GRID applications, particularly with regard to issues such as accounting and resource brokering. However, its heterogeneity, the size and complexity of the architectures involved, and its integral connection with local, national and super-national networks, prevent it from being considered as a cluster of workstations.
