ATLAS Trigger/DAQ Real-time Use of GÉANT u. Wish to test remote processing for Level ATLAS Trigger/DAQ Real-time Use of GÉANT u. Wish to test remote processing for Level 3 Trigger u. Way to make strong links on-off line Grids u. CERN NBI Krakow Manchester involved u. Slides from Bob Dobinson Dec 02 Trigger/DAQ Week u. Would be part of Data. Grid WP 7 collaboration with Dante u. WP 7 Response: n Would investigate aspects of interactive Grid computing n Would strengthen the collaboration with Dante n Does not use Middleware eg globus (but may well need AAA in the future) Grid.
