This tutorial provides a detailed introduction to SimTools, a powerful toolkit designed for event generation and data analysis using JSF and Jupiter frameworks. The guide covers installation procedures, accessing JSF classes, and navigating through essential examples. Users will learn to utilize various components, such as Leda for analysis and physsim for event generation. With precompiled binaries and comprehensive support for data management, SimTools facilitates both interactive and batch processing of complex simulation tasks. Updated regularly, it’s an essential resource for simulation studies.

  1. Introduction to SimTools Akiya Miyamoto KEK June 2005

  2. Plan of Tutorials • JSF • Intorudction, • Go through examples • learn how to access JSF classes • Jupiter / Satellites • Intorudction • Go through examples • Kick-off studies

  3. Information on the web • http://acfahep.kek.jp/subg/sim/simtools • http://www-jlc.kek.jp/subg/offl/jsf • http://jlccvs.kek.jp/

  4. Getting started with SimTools • SimTools is a collection of precompiled binaries of JSF, Jupiter, Satellites and related package. • Compiled on Redhat 9 linux, using gcc 2.2.2 • Requires ROOT-4.03.04 • Package will be updated every 1 or 2 months • Web site - http://acfahep.kek.jp/subg/sim/simtools • For installation, • Download from the web site • Edit setup.bash properly • Do "source setup.bash"

  5. Files in SimTools SimTools tools lcbase Leda jsf Physsim Jupiter Uranus Satellites docs examples QuickSim exam01 ..... Jupiter Satellites setup.bash Readme

  6. Functions of each components • lcbase : configuration files • Leda : Analysis tools (Kalman fitter, 4vector and jet findinder utilities ) • jsf : Root-based framework • lclib : QuickSim and other fortran based utilities • physsim : Helas-based generator • Jupiter : Full simulation based on Geant4 • Uranus : Data analysis packages • Satellites : Data analysis packages for MC data • We use only C++, except old fortran tools. • Link to various tools at http://acfahep.kek.jp/subg/sim/soft • All packages are kept in the CVS. Accessible from http://jlccvs.kek.jp/

  7. Setup.bash • # .bashrc • # Following two lines are essential • export SIMTOOLS_DIR=/home/sample/SimTools • export ROOTSYS=/home/root/root-4.03.04 • # next three lines are required to compile package • export JDK_HOME=/home/soft/JDK/j2sdk1.4.2_06 • export G4INSTALL=/home/soft/Geant4/geant4.6.1 • export LCIO=/home/soft/lcio/v01-03 • ..........

  8. .rootrc • ROOT uses .rootrc file to set configuration parameters. • Following two parameters must be defined to run JSF. • .rootrc file is in your current directory or in your home directory.

  9. JSF • JSF provides common framework for studies using • Quick Simulator • Jupiter/Satellites • To start interactive session of jsf, do$ jsf gui.CJSF control panel popes up

  10. Using JSF Control Panel • Controls menu • run mode • generator type • generator parameters • pythia • event type • zh • save parameters • Next Event button

  11. Batch Run • root option: • -b : run without X • -q : quit at the end • jsf option • --maxevt=N : N is number of events $jsf -b -q --maxevt=100 gui.C

  12. JSF Basics

  13. JSF features - 1 • JSF is based on ROOT • User needs to lean just one language, C+ • JSF provides a framework for modular analyses • Common framework for event generation, detector simulation, and analyses. • Same framework for beam test data analysis • Unified framework for interactive and batch jobs • GUI for control of an interactive run Histogram and event display packages included • A file similar to .rootrc is used to set parameter. • Default values an be overidden by command line argument at run time.

  14. JSF Features – 2 • Object I/O • Each modules can save/read their event data as branches of a root tree. • Job parameters, histograms, ntuples and private analysis tree can be saved in the same file • Packages • Included in the release • Pythia6.3, Bases/Spring++, ZVTOP, JETNET, BSGEN • Provided as separated packages • Physsim (Event generators and analysis utilities) • LCLIB (QuickSim, Helas) • Jupiter (Geant4) • Uranus/Satellites

  15. JSF Conponents • Libraries ( $JSFROOT/lib ) • Pre-compiled C++ classes to build JSF applicationsuch as libJSFGenerator.so, libJSFQuickSim.so, … • Executables (main program ) ($JSFROOT/bin) • “jsf” command : built with ROOT+libJSF.so • Macros ($JSFROOT/macro) • C++ program is used as Macro thanks to CINT(No need to compile and link) • In JSF, Macros are used to set run parametersand provide a simple analysis code.gui.C, GUIMainMacro.C, UserAnalysis.C

  16. Create modules • Jon Initialization • Begin Run • Event analysis • End Run • Job Termination JSF Kernel • JSF is a framework for event-by-event data analysis • Provides a modular framework suitable for analysis consists of several sub-detectors • Job flow control • Job flow is controlled by a class, JSFSteer • Analysis modules are inherited from a class, JSFModule • Member functions of JSFModuleInitialize(), BeginRun(..), Process(…), EndRun(), Terminate() JSF job flow concept A simple example without Macros is prepared in $JSFROOT/example/ZHStudy

  17. JSF Kernel - FileIO • A class, JSFEventBuf, is defined by JSFModule • It is used to define branch of a ROOT Tree ( used to save/get event data ) • JSFModule JSFEventBuf : 1-to-1 correspondance • Information of JSFModule written in a root file is used to define branch for read-in data. • In a user program, • To get pointer to JSFModule objects, mod= (JSFModule*) gJSF->FindModule(“module_name”) • To get pointer to JSFEventBuf objects, buf=(JSFEventBuf*)mod->EventBuf()

  18. Access to JSFModule and JSFEventBuf • In script • JSFSteer *jsf (defined in gui.C)jsf->GetEventNumber(); JSFXXX *mod=(JSFXXX*)jsf->FindModule("JSFXXX"); JSFXXXBuf *buf=(JSFXXXBuf*)mod->EventBuf(); • In compiled code, • JSFSteer *gJSF (defined in JSFSteer.h)

  19. Useful Web information • JSF Class Documents • CVS • http://jlccvs.kek.jp/

  20. Parameter file • All parameters are managed by JSFEnv class • In the userprogram, they are obtained by a method,JSFEnv::GetValue(“Parameter.name”,default) • At run time, paremetercan be changed by three method • In a file, jsf.confParameter.Name: value #!argname # comments …. • As a command line argument, like $ jsf –argname=value gui.C • Through the popup menues of JSF Control Panel Each user can add their own menu by a function, UserMenu() argname is an alias of Parameter.Nameused to parse command line argument

  21. Macro in JSF • In JSF, macros ( xxx.C file ), are used extensively to define type of jobs and job parameters. Important macro files in $JSFROOT/macro directory GUIMainMacro.C : Define a standard set of modules and their parameters gui.C : Load GUIMainMacro.C and libraries for GUI UserAnalysis.C : An sample user macro file for Initialization, event analysis and drawing histogram

  22. JSF – First example in SimTols • Examples inSimTools$ cd [SimTools]/examples/JSF_QuickSim/exam01$ jsf gui.CJSF control panel popes up

  23. UserAnalsis.C • Example in $JSFROOT/macro/UserAnalysis.C • Three functions: • UserInitialize() : Called at Job initializationdefine Histgrams, etc. • UserAnalysis() : Called at each eventfor event analysis • DrawHist() : Called to draw histogram
