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

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
• 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 ?
  dont 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

IGUANA Software Development Phases

• Dec 2002 Fully functional (pre-production)
  system
• Dec 2004 Production User Analysis Environment

IGUANA Prototypes and Applications
Completed successfully Oct 1999 (see e.g. CMS
internal review)

• 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

The CMS IGUANA Project Summary

• Scope provision/deployment of a 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

• Together with build, release, distribution and
  documentation systems

IGUANA is fully compatible with CERN/IT / LHC
strategy
Priority is CMS (but the vast majority of IGUANA
is generic)

• Status
• Evaluation of individual technologies and
  baseline choices completed
• Prototypes (based on IGUANA toolkit) now
  developing into applications
• 2D/3D interactive detector and event display
• Interactive (persistent) histogram and tag
  analysis, plotting, fitting, etc.
• On-line monitoring applications (test-beams,
  QA/QC labs, etc.)
• Functional Prototype (CMS milestone) June
