1. Update on CHEP from the Computing Speaker Committee G. Carlino (INFN Napoli) on behalf of the CSC ICB, October 20 2011

2. Important Dates – Atlas internal submission deadline: October 7 th 2011 – Abstract submission deadline: October 28 th 2011 – Notification of acceptance: December 19 th 2011 – End of early registration: January 31 st 2012 WLCG Workshop: May 19 – 20 (Saturday – Sunday) New York May 21-25 2012 – The conference will be held at NYU’s Skirball Center (plenary sessions) and the nearby Kimmel Center (parallel sessions), located in Greenwich Village in Lower Manhattan, NY. www.chep2012.org

3. Parallel Sessions Online Computing Event Processing – Event generation, simulation and reconstruction; Detector geometries; Physics analysis; Tools and Techniques for data classification and parameter fitting; Event visualization and data presentation; Frameworks for event processing; Toolkits for simulation, reconstruction and analysis; Event data models Distributed Processing and Analysis on Grids and Clouds – Distributed data processing; Data management; Distributed analysis; Distributed processing experience including experience with Grids and Clouds; Experience with real productions and data challenges; Experience with real analysis using distributed resources; Interactive analysis using distributed resources; Solutions for coping with a heterogeneous environment; Experience with virtualization; Mobile computing; Monitoring of user jobs and data, Grid/Cloud software and monitoring tools; Global usage and management of resources; Grid/Cloud middleware interoperability; Grid/Cloud middleware reliability; Grid/Cloud security; Evolution and perspective of Grid and Clouds; Experiment specific middleware applications. Computer Facilities, Production Grids and Networking – Basic hardware, benchmarks and experience; Hardware trends and issues such as multi-core, GPU, FPGA, etc; Fabric virtualization; Fabric management and administration; Local site I/O and data access; Mass storage systems; Local and wide area networking. Software Engineering, Data Stores and Databases – Programming techniques and tools; Software testing and quality assurance; Configuration management; Software build, release and distribution tools; Documentation; Foundation and utility libraries; Mathematical libraries; Component models; Object dictionaries; Scripting; Event stores; Metadata and supporting infrastructure; Databases. Collaborative tools

4. ATLAS abstracts We have got a very large number of abstracts: 80 https://indico.cern.ch/conferenceDisplay.py?confId=152073 Event Processing: 17 Distributed Processing and Analysis on Grids and Clouds: 35 Computer Facilities, Production Grids and Networking: 8 Software Engineering, Data Stores and Databases: 18 Collaborative tools: 2 + Online: 23 (TDAQ Speaker Com) Large majority asking for an oral presentation

5. ATLAS abstracts review In progress – Reviewers: Eric Lancon, Andrej Filpcic, Torre Wenaus, G.C. – We plan to finish by Wednesday 26 We need to select abstracts really deserving an oral presentation (factor ~1/2) – Not many slots available in the parallel sessions (Michael) – Large availability in the poster sessions The CSC will submit all the abstracts under the Atlas Collaboration name by Friday 28 Speakers will be selected after the abstract submission deadline taking into account talks given in the last years and in collaboration with the activities coordinators Names will be communicated to CHEP after the abstract notification of acceptance (agreement with organizers)

6. ATLAS talks & proceedings reviews CHEP wants the proceedings ready before the conference – Talks and Proceedings reviews almost at the same time. Heavy load for the CSC – We need great help from computing and software experts for both reviews At least 8/10 reviewers – Deadlines not yet defined: about two weeks before for talks and posters earlier for proceedings, how much earlier depends on the number of reviewers helping us
