    1. Grappa: Grid access portal for physics applications Status & Schedule April 2002 Shava Smallen Extreme! Computing Laboratory Department of Physics Indiana University

    2. Motivation for Grappa Lots of GriPhyN/Grid services Requires a good deal of expertise more than what many users want to know Common approach is a Grid portal

    4. Current Version Prototype based on existing technology (XCAT Science Portal) Learning experience Demo at ATLAS Software Week - March 2002 Allow user to submit sequence of job options files to US-ATLAS testbed resources File staging, remote job option file editing, basic monitoring, ad-hoc viz Packaged with Pacman and posted to http://iuatlas.physics.indiana.edu/grappa

    5. Current Architecture I will expand on the boxes in blue in future slidesI will expand on the boxes in blue in future slides

    6. Next Version Virtual Data Browser based on Virtual Data System 1.0 (May release date) Geared towards release Currently working on design Provide functionality analogous to that of a web browser Creation of virtual data interface to VDL to create transformations and derivations Searching of virtual data interface to VDC API User Profile credential mgmt, resource mgmt, etc.

    7. Next Architecture (tentative) I will expand on the boxes in blue in future slidesI will expand on the boxes in blue in future slides

    8. Where are we now?

    9. Tentative Schedule

    10. Relevance to Testbed Current version Individuals can install demo in own space Next version Initially start with one portal and then increase with usage Dependencies (other than VDT) Java 1.3 (probably 1.4 as soon as CoG supports it) MyProxy server (at least 2)
