Presentation of SuperB computing resource estimates based on an extrapolation from the BaBar computing model. Added 20.9.2011 (Steffen): Please note that cost numbers in the talk are incorrect (based on a typo in the spreadsheet). Please refer to the updated spreadsheet for the correct numbers.

Speaker: Dr Steffen Luitz (SLAC)

14:00 Accelerator Computing Infrastructure & Controls R&D Introduction

The SuperB Accelerator complex requires a large amount of computing tools mainly dedicated to three different purpose: implementation and maintenance of documentation and project management; beam simulation and controls; data monitors, presentation and correlation with the experiment. In the mean time those tools require identification, security, accessibility for large and international community. This is an opportunity to develop new concepts in accelerators controls and realize a new computing infrastructure. Requirements, preliminary ideas and structure design will be presented.

Speaker: Giovanni Mazzitelli (LNF)

14:30 The SuperB Accelerator Control System - Plans and R&D Status

!CHAOS is a new project under development at INFN aimed at the design and validation of a new paradigm of control system for particle accelerators that goes beyond the so called standard model. The key points of the new development are the high level of abstraction of services and components, the implementation of high-performance software technologies for the continuous distribution and storage of data, a new topology allowing high scalability of services and performance, an intrinsic redundancy of components avoiding any point of failure. The talk will present the !CHAOS design concept, the preliminary results, the future research program and the plans in the perspective of SuperB project.

Speaker: Luciano Catani (ROMA2)

15:10 ETD/Online for the SuperB Detector - Plans and R&D Status

This talk will give an overview of the proposed Electronics, Trigger, Data Acquisition and Online (ETD/Online) system for the SuperB detector and the associated R&D activities. The current baseline design will allow up to 150 kTriggers/s and 75kByte event size with negligible dead time (<=1%). It builds upon lessons learned in the BaBar and LHC experiments and implements simple, fully synchronous front-ends, a scalable ROM and back-end architecture and utilizes commercial off-the-shelf components where possible.

17:20 ALICE experience using Coverity

This talk will convey the experience of using Coverity for AliRoot software in A Large Ion Collider Experiment (ALICE). AliRoot consistently undergoes intensive development and release cycles, thus creating an increasing demand for automated high precision tools aiding developers in maintaining coding standards and ensuring code correctness. Coverity as a software solution, providing both static code analysis facilities and a centralised web interface, is actively enforced within the collaboration. The talk will start by describing the approach taken to set up Coverity and the automation process. It will also look at the use policy and the observed effects. The presentation will then explore checkers of varying impact with few examples of observed defects. In addition, examples of false positive cases will be presented with an explanation on how to model Coverity to ignore them. Thirdly, the talk will provide a critical evaluation of the application of Coverity to the AliRoot code with some considerations on the usage of automated tools in High Energy Physics (HEP) experiment software development. In conclusion, the talk will explore additional tools extensively used within ALICE for ensuring good coding standards.
