Mr Sverre Jarp (CERN)13/02/2006, 15:00Software Tools and Information Systemsoral presentationHEP programs commonly have very flat execution profiles, implying that the execution ime is spread over many routines/methods. Consequently, compiler optimization should be applied to the whole program and not just a few inner loops. In this talk I, nevertheless, discuss the value of extracting some of the most solicited routines (relatively speaking) and using them to gauge overall...Go to contribution page

Mr Matthias Schneebeli (Paul Scherrer Institute, Switzerland)13/02/2006, 17:00Software Tools and Information Systemsoral presentationThis talk presents a new approach of writing analysis frameworks. We will point out a way of generating analysis frameworks out of a short experiment description. The generation process is completely experiment independent and can thus be applied to any event based analysis. The presentation will focus on a software package called ROME. This software generates analysis frameworks which...Go to contribution page

Mr Florian Urmetzer (Research Assistant in the ACET centre, The University of Reading, UK)14/02/2006, 14:40Software Tools and Information Systemsoral presentationOngoing research has shown that testing grid software is complex. Automated testing mechanisms seem to be widely used, but are critically discussed on account of their efficiency and correctness in finding errors. Especially when programming distributed collaborative systems, structures get complex and systems get more error-prone. Past projects done by the authors have shown that the...Go to contribution page
