  1. The CMS IGUANA Project (Interactive Graphical User Analysis) George Alverson, Ianna Gaponenko and Lucas Taylor Northeastern University, Boston CHEP 2000, Padova February, 2000

  2. Introduction • Scope covers provision of software toolkit for: • Interactive Physics Analysis • 2D/3D interactive detector and event display • On-line monitoring applications (test-beams, QA/QC labs, etc.) • Graphical User Interfaces • Build, release, distribution and documentation systems for above • IGUANA • May 1999: new CMS OO software project was initiated: • 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 The CMS IGUANA Project

  3. IGUANA Strategy • Develop a well-engineered toolkit of software components • Leads to maintainable software which can evolve smoothly • Can develop, acquire, deploy, maintain, & replace components separately • Can build many different applications from various sets of components • Leverage other related efforts • Commercial, public-domain, and HEP • Fully compatible with CERN/IT strategy and LHC++ • Aside remark: sharing experience is often more valuable than sharing code • To start with, be more pragmatic than rigorous • choose a specific set of tools early on  don’t be overly general • rapid prototyping  verify technologies/design • develop a few realistic applications  get early user feedback • IGUANA must support a rapidly increasing OO developer & user base in CMS • Core software development, detector, trigger, and physics studies The CMS IGUANA Project

  5. Formal creation of IGUANA project Apr Evaluation and prototyping of individual technologies IGUANA Infrastructure • Software repository • Build, release, distribution, and documentation systems • System configuration • Inter-project configuration management (e.g. with ORCA) May Jun Jul Demonstrate Integration of all baseline technologies 1999 Aug Sep Oct Nov Baseline choice of IGUANA technologies Dec Development of IGUANA “Functional Prototype” with real user applications Jan Feb CHEP 2000 Mar Apr May CMS Milestone: “Functional Prototype” 2000 Development of pre-production IGUANA toolkit and applications Jun Jul Aug Sep Oct IGUANA Software Development Phases • Dec 2002 Fully functional (pre-production) system • Dec 2004 Production User Analysis Environment The CMS IGUANA Project

  6. IGUANA prototypes • demonstrate functionality of individual technologies • verify compatibility of technologies and overall design 1) Embedding OpenGL and OpenInventor Components in Qt 2) Embedding Xt and Motif Components in Qt 3) Multi-document architecture 4) Interactive 3D Detector and Event Visualisation with ORCA 5) 2D Display for Graphical Online Monitoring and Control 6) Retrieval/Display of OO Histograms/Tags with Objectivity IGUANA Prototypes and Applications • IGUANA Applications • Interactive visualisation • Initial development for CMS reconstruction with ORCA  talk by D. Stickland • To be deployed with OSCAR, test beams, ...  talks by M. Schöder L. Silvestris • Physics Analysis Tools • Generic OO histogramming and Objectivity tag analysis tools (building on LHC++) • ORCA, ECAL APD acceptance laboratory, test beams,… Configuration Management Software: common systems for all CMS • cvs repository with SCRAM (CMS product) for build, release & distribution Completed successfully Oct 1999 (see e.g. CMS internal review) The CMS IGUANA Project

  7. Generic detector display (based on GEANT geometry) Reconstructed (ORCA) object IGUANA Event Display • 2D graphics: • X11 and Qt • 3D graphics: • OpenGL • OpenInventor • HEPVis • + IGUANA extensions The CMS IGUANA Project
