Database report

In order to avoid tedious retyping and correction of material held in this database the network includes here a brief statement of the overall direction of its collaborations based on what was stated in the agreed work programme.

The three topics which bind this network together are parallel systems, advanced compilation techniques and artificial intelligence (AI) with a common substrate in the programming language Lisp. The research aim of this project is to demonstrate the advantages accruing from the combination of these three technologies to build a virtual multicomputer for large scale symbolic applications. A virtual multicomputer is an ephemeral, persistent machine of available heterogenous computing resources (workstation, shared-memory multiprocessor, distributed memory multiprocessor, array processor). The system supports a virtual processor abstraction to distribute data and tasks across the multicomputer, the actual physical composition of which may change dynamically. Our practical objective is to make it straightforward to prototype dynamic distributed symbolic applications using whatever resources are available (probably networked workstations), but so that the developed program can also be run on more exotic hardware with reprogramming.

Fuller and up-to-date details of activities (past and present) are held on the World Wide Web. In particular, the online repository of project software and information held at Southampton has been set up and is now widely used by the partners. This service has been used for project-related research as well as information dissemination. The repository may be accessed directly with the URL:
