Dr Ariel Garcia (FORSCHUNGSZENTRUM KARLSRUHE, GERMANY)03/11/2008, 14:001. Computing TechnologyParallel Talkg-Eclipse is both a user friendly graphical user interface and a programming framework for accessing Grid and Cloud infrastructures. Based on the extension mechanism of the well known Eclipse platform, it provides a middleware independent core implementation including standardized user interface components. Based on these components, implementations for any available Grid and Cloud middleware...Go to contribution page

Mikhail Titov (Moscow Physical Engineering Inst. (MePhI))03/11/2008, 14:251. Computing TechnologyParallel TalkThere is ATLAS wide policy how different types of data is distributed between centers of different level (T0/T1/Tn) it is well defined and centrally operated activity (uses Atlas Central Services which include Catalogue services, Sites services, T0 services, Panda Services and etc). At the same ATLAS Operations Group designed user oriented services to allow ATLAS physicists to place data...Go to contribution page

Paul Nilsson (University of Texas at Arlington)03/11/2008, 14:501. Computing TechnologyParallel TalkThe PanDA system was developed by US ATLAS to meet the requirements for full scale production and distributed analysis processing for the ATLAS Experiment at CERN. The system provides an integrated service architecture with late binding of job, maximal automation through layered services, tight binding with the ATLAS Distributed Data Management system, advanced job recovery and error discovery...Go to contribution page

Mr Andrei Gheata (ISS/CERN)03/11/2008, 15:151. Computing TechnologyParallel TalkThe talk will describe the current status of the offline analysis framework used in ALICE. The software was designed and optimized to take advantage of distributed computing resources and be compatible with ALICE computing model. The framwork's main features: possibility to use parallelism in PROOF or GRID environments, transparency of the computing infrastructure and data model, scalability...Go to contribution page

Giuseppe Codispoti (Dipartimento di Fisica)03/11/2008, 16:101. Computing TechnologyParallel TalkCRAB (CMS Remote Analysis Builder) is the tool used by CMS to enable running physics analysis in a transparent manner over data distributed across many sites. It abstracts out the interaction with the underlying batch farms, grid infrastructure and CMS workload management tools, such that it is easily usable by non-experts. CRAB can be used as a direct interface to the computing system or...Go to contribution page

Pier Paolo Ricci (INFN CNAF)03/11/2008, 16:351. Computing TechnologyParallel TalkThe activities in the last 5 years for the storage access at the INFN CNAF Tier1 can be enlisted under two different solutions efficiently used in production: the CASTOR software, developed by CERN, for Hierarchical Storage Manager (HSM), and the General Parallel File System (GPFS), by IBM, for the disk resource management. In addition, since last year, a promising alternative solution for...Go to contribution page

Hegoi Garitaonandia (NIKHEF)03/11/2008, 17:001. Computing TechnologyParallel TalkThe ATLAS experiment at CERN will require about 4000 CPUs for the online data acquisition system (DAQ). When the DAQ system experiences software errors, such as event selection algorithm problems, crashes or timeouts, the fault tolerance mechanism routes the corresponding event data to the so called debug stream. During first beam commissioning and early data taking, a large fraction of events...Go to contribution page

Dr Stuart Wakefield (Imperial College London)03/11/2008, 17:251. Computing TechnologyParallel TalkFrom its conception the job management system has been distributed to increase scalability and robustness. The system consists of several applications (called prodagents) which each manage Monte Carlo, reconstruction and skimming jobs on collections of sites within different Grid environments (OSG, NorduGrid?, LCG) and submission systems (GlideIn?, local batch, etc..). Production of...Go to contribution page

Dr Elena Solfaroli (INFN RomaI & Universita' di Roma La Sapienza), Dr Monica Verducci (INFN RomaI)03/11/2008, 17:501. Computing TechnologyParallel TalkATLAS is a large multipurpose detector, presently in the final phase of construction at LHC, the CERN Large Hadron Collider accelerator. In ATLAS the muon detection is performed by a huge magnetic spectrometer, built with the Monitored Drift Tube (MDT) technology. It consists of more than 1,000 chambers and 350,000 drift tubes, which have to be controlled to a spatial accuracy better...Go to contribution page
