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

  3. KEK ILC Computing Outside KEK KEK DMZ Zone GW KEKCC-Gate JLCGATE router FJ Network jlclogin jlclogin2 jlccpu11 . . . jlccpu06 jlccpu07 jlccpuxx

  4. CPU Configuration jlclogin RedHat 9.0 Will be terminated /home /data, /data2, /data3 /data4/users /data4/soft/samples jlclogin2 SL4.2 /home/data2, /daat3, /data4 ( NFS mount of jlclogin disk) /data5, /data6 : for public soft files.

  5. Local commands • Submit job • $ submit [-h host] command • Submit job as a batch job • $ submit command > log 2>&1 & ( in case of bash ) • Show job status in CPU server • $ showjob • Monitor CPU loads of each CPU server • $ cpui • To kill job running at CPU server • $ rsh jlccpuXX “ps –ef | grep username” • $ rsh jlccpuXX “kill –15 XXXX”

  6. How to setup your account $ cd $ cp /home/miyamoto/Tutorials/misc/dot.rootrc ~/.rootrc $ mkdir Tutorials $ cd Tutorials $ cp /proj/soft/Release/1.21/setup.bash . $ source setup.bash • You are ready to run jsf/jupiter/satellites program

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

  9. 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/

  10. 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

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

  12. 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

  13. JSF Basics

  14. 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.

  15. 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

  16. 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

  17. 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

  18. 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()

  19. 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)

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

  21. 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

  22. 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

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

  24. 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
