  1. OSG All Hands March 2010, Fermilab Global Communities Massimo Lamanna – CERN IT Experiment Support

  2. LHC Computing (Grid) • Powerful federation of data-handling infrastructures • Grids, but also Tier3 federations, probably cloud services • Different things but not contradicting • Technologies (and buzzwords) come and go... • Grid was not from HEP • success in HEP  our community (experiments, laboratories, …) + our requirements • Clouds are already here (and evolving) • Contributions from outside are welcome • We shouldn't be scared to adopt market standards! • Other communities are now talking PetaBytes (and more) • But we are already there • We have an unique community • Other sciences are not there (yet). Business communities do not always have the same multi-year vision and in most of the cases not even the policy makers (politics) • pp collisions at LHC! • More physicists concentrate on physics. Engineering-minded people could team up M. Lamanna CERN IT (Exp. Support)

  3. Future global collaboration • Collisions force us to refocus and be more pragmatic • Provide the missing pieces / Reuse existing solution from others • How to conciliate evolution and smooth operations? • Perturbing the system is not acceptable • New technologies: • Or just catching up with the evolution from industry (and benefitting from it!) • Challenges ahead (for HEP community and especially ATLAS and CMS) • User support ( 1000+ users... we are a scientific collaboration and not a corporate help desk) • Distributed data management • Virtualisation • ... M. Lamanna CERN IT (Exp. Support)

  4. Future global collaboration “Support” Users Sites • Base services for the next 1-2-5 years? • “simpler“ (and not more complex at least on the user side) • more “fundamental” (as in the word “foundation”) • To be the foundation of complex experiment services (PanDA, Phedex, ...) • base mechanisms, e.g. Distributed semaphore, distributed messaging, distributed * • reliable functional end-points, for example to store data and access it effectively • Applications will continue to build complex stuff: example: Experiments SAGA (LSU) e.g. Lattice QCD PanDA (ATLAS) DIRAC (LHCb) Other applications and contributions: e.g. Google Summer Of Code 2010 WLCG TeraGRID CLOUDs
