User (HEP) Requirements

1. JRA1/SA3 All Hands Meeting CERN, 15-16 December 2009 Patricia Méndez Lorenzo (NA4/HEP) User (HEP) Requirements

2. Abstract • During the last TMB Meeting (09/12/09) the EGEE-JRA1 Tasks for 2009/2010 werediscussed • The User expectations and requirements in terms of the services included in the listwerequeried (NA4 task) • The followingslidescontains a (non-exhaustive) answers of the WLCG community • Inputs from Andrea Sciaba, Roberto Santinelli, Alessandro di Girolamo and Simone Campana JRA1/SA3 All Hands Meeting

3. Services presented in theseslides The highlighted services have been required and/or discussed by at least one LHC experiment JRA1/SA3 All Hands Meeting

4. CMS Statements JRA1/SA3 All Hands Meeting

5. ALICE Statements • ALICE have asked for the deployment (at all sites) of the CREAM-CE in parallelwith the LCG-CE sinceSummer 2008 • Usage: Direct submission mode • The goal is the full deprecation on the gLite-WMS • The LCG-CE deprecation on light of CREAM-CE is not yetdefined. The use of the WMS (and therefore of any new version) isforeseen by ALICE during 2010 period JRA1/SA3 All Hands Meeting

6. ATLAS Statements In terms of the CREAM-CE, ATLAS have asked for the maintenance of the LCG-CE during the whole 2010 period. The priority of the new CE isthereforelow JRA1/SA3 All Hands Meeting
