Application’s Insert Points

Plug-in Applications- flexible: apps can use Triana in various ways, as a:

- GUI - remote control GUI- or in full inc. GAT

Triana Prototype

Distributed Triana Prototype Based around Triana Groups i.e. aggregate toolsDistribution policies:

HTC - high throughput/task farmingPeer to Peer - allow node to node communicationmiddleware independent – they DO NOT rely on any specific middleware e.g. JXTA, OGSA, Jini etc.

Galaxy Formation Code

Roger PhilpCardiff Centre for Computational

Science and Engineering

Galaxy Star Formation Simulations • galaxy and star formation simulations are typically represented by 16-D data sets that require visualization from different perspectives• a series particles in three dimensions and their associate properties as a snap shots in time. • user would like to visualize this data as an animation in two dimensions and then vary the point of view and project of that particular two dimensional slice and re-run the animation.
