Pervasive Collaborative Computing Environment
(PCCE)

• Personnel - LBNL Deb Agarwal, Charles
  McParland, and Marcia Perry
• Personnel UW Miron Livny

Objective Support the day-to-day collaboration
needs of scientists by building tools that
leverage off the web, Grid services, existing
standards, and existing tools. The final
environment needs to support a continuum of
collaboration capabilities.
