Feb 2007

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

3. CPU Configuration jlclogin2 SL4.2
/home /data4/jlc, /data7/jlc ; generic user files
/data5, /data6 : for soft files.

4. 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”

5. How to setup your account
$ cd
$ cp /home/miyamoto/Tutorials/misc/dot.rootrc ~/.rootrc
$ mkdir Tutorials
$ cd Tutorials
$ cp /proj/soft/Release/1.35/setup.bash .
$ source setup.bash
You are ready to run jsf/jupiter/satellites program

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.

All packages are kept in the CVS. Accessible from

9. JSF JSF provides common framework for studies using Quick Simulator
Jupiter/Satellites
To start interactive session of jsf, do $ jsf gui.C JSF 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 $ jsf -b -q --maxevt=100 gui.C root option:
-b : run without X
-q : quit at the end
jsf option
--maxevt=N : N is number of events

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 ( $JSFROOT/lib )
Pre-compiled C++ classes to build JSF application such as libJSFGenerator.so, libJSFQuickSim.so, …
Executables (main program ) ($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 parameters and provide a simple analysis code. gui.C, GUIMainMacro.C, UserAnalysis.C

16. 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 JSFModule Initialize(), BeginRun(..), Process(…), EndRun(), Terminate()
JSF job flow concept
Create modules
Jon Initialization
Begin Run
Event analysis
End Run
Job Termination
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

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.conf Parameter.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.Name used 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.C JSF control panel popes up

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