Architecture – some requirements? Project types Centre Projects - % Type Resource Access Collaboratve Working Visualisation & User Information Based Compute Based 0 10 20 30 40 50 • Visualisation – complex renderings – composite data views – user-centric viewing, control or management of data sources. • Information – large distributed databases – correlation, query, merging and presentation • Collaborative – conferencing, – other interactive activities, e.g. planning, surgery • Resource – control, or participate in experiments – using specialised resources – eg telescopes, microscopes, chemistry robots. Conclude • Data centric (‘information grids’) and user/visualisation applications are at least as important as compute grids – we should look to these areas to drive the need for architectures & infrastructure in the medium term. • Note: at present 39% of these projects are developing their own infrastructure. This slide is the end of the ‘background’ section, time did not allow discussion of the remaining slides.
