Creating Federated Data Stores For The LHC

21 nov. 2011, 08:00 → 22 nov. 2011, 18:00 Europe/Paris

Auditorium (CC-IN2P3)

Andrew Hanushevsky (SLAC National Accelerator Laboratory), Jean-Yves Nief (CC-IN2P3)

Currently, three LHC experiments have deployed or are ready to deploy a federated model for experimental data access (i.e., ALICE, ATLAS, and CMS). While each experiment has taken a similar approach (i.e. xrootd), the implementations are sufficiently different to warrant a collaborative discussion of the specific needs that spurred a particular direction. Through a collaborative dialogue, this meeting hopes to expedite adoption and support of federated data access models in LHC by leveraging each other’s experience.
