  2. 1 GRID GridOneD Grid Cardiff Triana-Grid Group PPARC - Java Grid middleware based around Triana PSE GEO 600 1.6 PDRA Physics and Astronomy 3 PDRA 2 PhD Computer Science Triana-Grid Group EU- to create an Application Layer API – the GAT

  3. What is Triana?

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

  5. Triana Pluggable Architecture • Plug-in Applications • flexible: apps can use Triana in various ways, as a: • GUI • remote control GUI • or in full inc. GAT Triana Engine TCS Command Service Control Another Engine Triana TaskGraph Reader Triana Command Reader Triana TaskGraph Writer Triana Command Writer XML Reader WSFL Reader TCom Reader Other Reader XML Writer WSFL Writer TCom Writer Other Writer (BPEL4WS, Petrinet) Interactive Application’s Insert Points Interactive/Offline Communication Channels

  6. Actual Data Stream Potential Data Stream Active Sub Service Dormant Sub Service Triana Distributed Work-flow TS TS TS Command Service Control Command Service Control Command Service Control Client Client Client Server Server Server • Designed and Implemented Distributed Triana Work-flow • flexible distribution: based around Triana Groups • HPC and Pipelined distribution policies Triana Gateway Client Server TCS Command Service Control - Triana Service TS Triana User Interface - Triana ControllerService TCS • User interface: GUI/Command line TGUI TGUI

  7. 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

Command Server Scheduling Another Engine Triana Engine Pluggable engine Triana or other Distribution Middleware independent distributed task-graph Triana Distribution Other Grid Application Toolkit - GAT Grid Interoperability OGSA JXTA OGSA Jini Anon

  11. 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.

  14. Galaxy Formation Test Case Galaxy Formation Code Roger Philp Cardiff Centre for Computational Science and Engineering Grid Node Node Node Node Node Node • 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.
