Introduction Scope covers provision of software toolkit for: May 1999: new CMS OO software project was initiated: http: //cmsdoc. cern. ch/cmsoo/projects/IGUANA èInteractive Physics Analysis è 2 D/3 D interactive detector and event display èOn-line monitoring applications (test-beams, QA/QC labs, etc. ) èGraphical User Interfaces èBuild, release, distribution and documentation systems for above IGUANA Interactive: • used in real-time by physicists (not just batch) • dynamic control of program execution Graphical: • user interface control • data browsing and presentation User: • utility and ease-of-use by all CMS physicists Analysis: • numerical and statistical analysis of CMS data • also generally applicable elsewhere Ianna Gaponenko, Northeastern University, Boston The CMS IGUANA Project 2

IGUANA Strategy Develop a well-engineered toolkit of software components http: //cmsdoc. cern. ch/cmsoo/projects/IGUANA èLeads to maintainable software which can evolve smoothly èCan develop, acquire, deploy, maintain, & replace components separately èCan build many different applications from various sets of components Leverage other related efforts èCommercial, public-domain, and HEP èFully compatible with CERN/IT strategy and LHC++ * sharing experience is often more valuable than sharing code To start with, be more pragmatic than rigorous èchoose a specific set of tools early on èrapid prototyping èdevelop a few realistic applications don’t be overly general verify technologies/design get early user feedback IGUANA must support a rapidly increasing OO developer & user base in CMS èCore software development, detector, trigger, and physics studies Ianna Gaponenko, Northeastern University, Boston The CMS IGUANA Project 3
