Sommaire
ATLAS Analysis challenge
Goals
- measure "real" analysis job efficiency and turn around on several sites of a given cloud
- measure data access performance
- check load balancing between different users and different analysis tools (Ganga vs pAthena)
- check load balancing between analysis and MC production
First exercise on the FR Cloud in december 08 (proposition)
First exercise is a ganga-based limited in time (a few days) and requires careful attention of site administrators during that period,in particular network (internal & external), disk, cpu monitoring.
This first try can be run centrally. ATLAS coordination (Dan van der Ster and Johannes Elmsheuser) needs to know which sites to be tested and when. Any site in the Tiers_of_ATLAS list can participate.
