The initial research application will concentrate on the large-scale modelling of electro-seismic phenomena in fluid saturated material with specialised, parallel Finite-Difference Time-Domain (FDTD) and Discrete Element (DE) code being developed in-house.
ilyash, it's more than just a network. One server is running a "master" cluster server application, and the other servers are running the client. The master server sends out processing commands to other computers via different methods, Ethernet in a Beowulf cluster. A good Tech TV - Screensavers episode demonstrates exactly this is http://www.offmyserver.com/cgi-bin/store/cluster.html
That explains what a Beowulf cluster is, how to set one up, and underneath the picture, is a link to the Screen Savers show when they set it up.
