Plug-in Applications- flexible: apps can use Triana in various ways, as a:
- GUI - remote control GUI- or in full inc. GAT

Designed and Implemented Distributed Triana Work-flow- flexible distribution: based around Triana Groups- HPC and Pipelined distribution policies
Triana Gateway
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

Collaboration• Triana Users
– GEO 600 – Triana, as a quick-look system – distributed integration for coalescing binary search – Dave Demo later
– Cactus – Several methods of integration outlined – see next slide
– GriPhyN – using Triana as GUI for virtual file system – visit in Jan 20-24th 2003 – see next
• Potential Triana Users– AstroGrid – Considering GAT + Triana as front end –
proposed meetings - imminent – DAME – Considering using Triana as front end +
Gridlab services – PDRA is looking at Triana now– GridOneD Project – expansion bid for ‘Implementation
Team’ (11 persons) – 1st Quarter 2003.

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.
