What is Triana?

Remote Control Triana Triana Engine Command Service Control WSFL + Extensions A client logged on Persistent Service Triana Controller Service Wap Html/Java Decoupled Triana GUI from the Triana engine - standardized XML task-graphs - allows multiple devices to connect/disconnect - persistent service (TCS )

Distributed Triana Distributed Triana Prototype –Based around Triana Groups i.e. aggregate tools –Distribution policies: HTC - high throughput/task farming Pipelined - allow node to node communication middleware independent – they DO NOT rely on JXTA. Implementation –Uses ‘JXTAServe’ - a GAT for JXTA –Good feedback for the GAT –Will become GAT binding for JXTA

Galaxy Formation Code Roger Philp Cardiff 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.
