Presentation Transcript

  1. Michael Remijan • NCSA • Research Programmer • Web-based Distributed Programming • Databases • Java 259th fastest computer in the world National Center for Supercomputing Applications

  2. Applications Overview • Cross ID Federation (xid) • ALL-QSO • Astroforge 259th fastest computer in the world National Center for Supercomputing Applications

  3. Cross ID Federation (xid) 259th fastest computer in the world National Center for Supercomputing Applications

  4. Most Surveys have great spatial locations Cross ID Federation (xid) • Problems: • Some have poor spatial locations • Things look different in different wavelengths (ROSAT) • 3 optical sources, 2 stars and something else • Generate better probabilities using astronomy knowledge • x1 2%, • x2 20% • x3 78% National Center for Supercomputing Applications

  5. ALL-QSO 259th fastest computer in the world National Center for Supercomputing Applications

  6. ALL-QSO • Quasars • Historically, difficult to confirm • Intense observation (spectroscopy) – blue spectrum • Many, many small surveys • Limited number of objects and data for those objects • Overlap between surveys • All-QSO • Collect all major surveys into one DB • Searching capability • Semi-intelligent “unique” tool • Cross-match for more information • Major success at early stages • Several submitted and ongoing paper (APJ) • QSO variability is correlates with properties in X-ray/radio or IR • Data-mining algorithms to detect new quasars (AISRP Proposals) • NCSA’s D2K • Condor & Teragrid • Save expenses for Hubble, Chandra, Spitzer 259th fastest computer in the world National Center for Supercomputing Applications

  7. ALL-QSO • Further development (AISRP Proposals) • “Unique” object selection • Only semi-intelligent • Currently: Weighting of general catalog quality • Development: Quality of data • “Repeat” object selection • Want objects observed several times. • Major Scientific Tool • Web application robust and load-balanced for high traffic • New types of access • VO compliance (VOTABLE) • Web Services with Java & Python examples to download • Java desktop GUI (SLOAN) • Pixelization Schemes (Hierarchical Triangular Mesh) • “What is everything known about QSOs, for all time, at all wavelengths, in this pixel of the sky? 259th fastest computer in the world National Center for Supercomputing Applications

  8. Astroforge www.astroforge.net 259th fastest computer in the world National Center for Supercomputing Applications

  9. Astroforge • Code • Archive • Hosted on Astroforge • Library • Link on Astroforge • Knowledge Center 259th fastest computer in the world National Center for Supercomputing Applications

  10. Astroforge • Further development (AISRP Proposals) • A lot depends on use • Feedback from users to make it better • Web Service access • Create versions & releases • Upload, edit, delete files • Searching • More sophisticated searching algorithms • Webcrawlers • Existing NCSA project • Identify software out on the web 259th fastest computer in the world National Center for Supercomputing Applications

  11. Thank You 259th fastest computer in the world National Center for Supercomputing Applications
