content
Content
  • TCD’s past experience with portals
  • Plans for WS-Pgrade and SCI-BUS
    • Integration with HELIO to build a portal for the Heliophysics community
    • Use WS-Pgrade as the standard user interface to Grid-Ireland’s computational and storage facility.
tcd and portals
TCD and portals
  • Migrating Desktop (2003-2008)
    • CrossGrid and Grid-Ireland sites
  • Ganga and Diane (2008-now)
    • Used to test jobs for the Costas’ arrays.
  • Genius (2004)
    • Used with EDG middleware
  • P-Grade
    • Deployment with Quattor profiles
    • GENE-VO applications developed in P-Grade
helio introduction
HELIO - Introduction

HELIO is designed to help the scientist in: finding, retrieving and analyzing data regarding the sun,

its related phenomena and their effects on: the Earth, and, the other planets of the Solar System.

Different User’s Profiles

  • Data and Metadata
  • from the various instruments are:
  • Dispersed
  • Non completely standardized
  • There is a complex feedback between data and metadata.

interesting areas
Interesting areas
  • User access:
    • Port the Helio Front End into WS-Pgrade ?
    • How to give access to IDL-Oriented users ?
  • Resources access:
    • How to merge the storage and processing services into SCI-BUS ?
    • How to merge the HELIO security model into SCI-BUS ?
  • General architecture issues:
    • How to merge the HELIO API ?
    • How to merge the other HELIO services ?
ws pgrade as grid ireland user interface
WS-PGrade as Grid Ireland User Interface
  • Move Grid Ireland users to WS-Pgrade.
    • How to support the users that still wand a text-based approach ?
