Introduction

Introduction

  • “User Analysis Environment”

    • data analysis and presentation

    • histograms, ntuples/tags, and plotting

    • interactive 2D/3D detector and event visualisation

    • graphical user interfaces

    • statistical and numerical analysis

  • “IGUANA” (Interactive Graphical User Analysis)

    • Recently created CMS project (May 1999)

    • Together with LHC++, addresses CMS needs for “User Analysis Environment”

    • Follow/collaborate with related activities

      (AIDA, HEPVis, Hippodraw, JAS, OpenScientist, ROOT, WIRED,...)

Iguana phases

IGUANA Phases

  • 1) Select Baseline technologies(completed)

    • design should allow for reasonable mixing of technologies...but...

      should concentrate on one specific set of tools early on

      • trying to be overly general can mean nothing concrete gets done!

  • 2) Prototypes(ongoing)

    • test each choice of technology with a realistic (if simplistic) prototype

    • test the mixing of the various technologies with prototypes

  • 3) Development / deployment of applications(started)

    • should start to evolve naturally from the prototypes

    • early involvement of end-users (don’t make products nobody wants)

  • Functional prototype milestone: June 2000

User Analysis Environment


Iguana component software strategy

IGUANA Component Software Strategy

  • Consistent with LHC++ strategy (and many specific components)

    • Combine (only the required) components to build a given application

    • Develop/acquire, test, deploy, maintain, & replace components individually

    • Leverage non-CMS efforts (commercial/free SW, common projects)

Iguana baseline toolkit for graphical user interfaces

IGUANA Baseline Toolkit forGraphical User Interfaces

  • Evaluation of widget sets led to choice of: Qt

    • Extensible OO GUI Toolkit with C++ API

    • Full set of “standard” widgets

    • Support for Unix/X11 (incl. Linux) and Windows 9x / NT

    • Free for all Unix platforms (~$1500/developer for NT)

    • Excellent documentation and examples

    • High-level 2D drawing classes with good off-screen rendering

  • Already a lot of interest from LHC++, ATLAS, HEPVis,...

    (since presentations at HEPVis99 and subsequent discussions)

User Analysis Environment


Iguana prototypes

IGUANA Prototypes

  • Prototypes should demonstrate (or not!):

    • functionality of individual technologies

    • (component-like) inter-operability of various technologies to make realistic applications

  • 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 from Objectivity

Prototype 1 embedding opengl openinventor components in qt

Prototype 1: Embedding OpenGL / OpenInventor Components in Qt

  • “QGL” extension for OpenGL http://www.troll.no/qt/opengl.html

    • OpenGL windows can be created & managed as any other Qt widget

  • “SoQt” extension for OpenInventor http://www.sim.no/

    • Needs OpenGL extension

    • Needed some “tweaking”

  • Aside remark:

  • LiveConnect extension for plug-inshttp://www.troll.no/qt/nsplugin.html

    • For both Navigator and Explorer

    • Full Qt functionality on Unix,W9x/NT

Prototype 6 retrieval display of oo histograms and tags from objectivity4

Prototype 6: Retrieval & Display of OO Histograms and Tags from Objectivity

  • None of the prototypes was a complete solution

    ...but the Qwt (Qt-based) solution was preferred

    • Fully OO (not even wrapped), hence easily extended

    • Well-integrated with the rest of the GUI

    • Only Qt is required

      • No need for OpenGL, OpenInventor, Mastersuite, IRIS Explorer,...

    • Good vector hardcopy (Postscript)

  • Strategy for Histogram display

    • Develop a new Qt-based histogram widget (light-weight and free)

    • Collaboration with others (LHC++, etc...)

    • For “3D views of plots” (e.g. Lego plots) evaluate:

      • Simple system based on Qt

      • Fully functional 3D system (OpenInventor)

  • User Analysis Environment


    From prototypes to project software configuration management

    From Prototypes to Project: Software Configuration Management

    • Software repository

      • CVS-based (similar to ORCA)

      • Minimise external dependencies for each package (library)

    • Build and release system

      • SCRAM-based (similar to ORCA)

    • Documentation

      • doxygen auto-documentation tool

      • examples in progress

    IGUANA between now and June 2000(towards the Functional Prototype Milestone)

    • CMSCAN Development (Detector &Event Visualisation Toolkit)

      • Conversion of GUI from Motif to Qt (and feedback to HEPVis)

      • Correlation/picking of information (graphics / GUI  underlying data)

      • 2D views and non-cartesian transformations (-, fish-eye,...)

    • CMSCAN Deployment

      • Full range of reconstructed objects (ORCA3 and ORCA 4)

      • OO detector display tools (GEANT4 / OSCAR and ORCA)

      • Test-beam visualisation systems

    • Physics Analysis Tools

      • Continue prototypes in close collaboration with LHC++, HEPVis, etc.

      • IGUANA focus is more on graphics and GUI’s (rather than scripting, statistical analysis tools, histogram/tag storage and retrieval, etc.)

      • Definition of generic IGUANA deliverables (in context of LHC++)

      • Development of GUI’s for test-beam monitoring, control, analysis,...

    Summary

    Summary

    • Technology Evaluations and Choices (completed)

      • Modular software components

        • Software is robust, maintainable and can evolve

        • Leverage efforts elsewhere (HEP, free software community, commerce)

      • Baseline choice of a specific set of tools has been made

    • Prototyping (ongoing)

      • Realistic tests of each choice of technology and mixing of technologies

      • Interactive 3D detector / event visualisation (with ORCA)

      • Browsing and display of histograms and tags in Objectivity DB

    • Development / deployment of CMS applications (started)

      • ORCA underway, start with OSCAR and test-beams by end 1999

    • Excellent progress has been made so far but...

    • ...timely continuation is contingent on sufficient SW engineering

    • Functional prototype milestone: June 2000
