Basic on UI commands Ruhani Khanna (INFN-LNS) VIII International GEANT4 school Tuesday 19thNovember, 2019 Belgrade, Serbia 1 softwareschool.infnlns@gmail.com
Lesson outline What interfaces are used for Methods to use UI commands Universal approach softwareschool.infnlns@gmail.com
What are interfaces used for 3 GEANT4 Provides necessary components to describe and solve particle transport simulation problems - Problem description = geometry, particles, physics - Problem solution = step-by- step particle transport computation while providing interaction points - softwareschool.infnlns@gmail.com
What are interfaces used for Application programmer 4 GEANT4 Provides necessary components to describe and solve particle transport simulation problems - Develops simulation application using components in the toolkit - Requires knowledge of both the C++ and simulation toolkit - Problem description = geometry, particles, physics - Problem solution = step-by- step particle transport computation while providing interaction points - softwareschool.infnlns@gmail.com
What are interfaces used for Application programmer 5 GEANT4 Provides necessary components to describe and solve particle transport simulation problems - Develops simulation application using components in the toolkit - Requires knowledge of both the C++ and simulation toolkit - Problem description = geometry, particles, physics - Problem solution = step-by- step particle transport computation while providing interaction points - User interfaces enables the running of GEANT4 application without using c++ language softwareschool.infnlns@gmail.com
UI commands /run/verbose 1 softwareschool.infnlns@gmail.com
UI commands command /run/verbose 1 Command directory Parameter(s) can be string, boolean, integer, omitted for default runManager -> SetVerboseLevel(1) Sets how much output the run manager will print softwareschool.infnlns@gmail.com
UI commands other examples Initializes the run (constructing geometry, physics and preparing user actions) /run/initialize /run/beamOn 100 Starts a run with 100 events /control/execute macroName Run all commands contained in a macro file List of built List of built- -in commands: in commands: GEANT4 Application Developers Guide, Chapter 7.1 softwareschool.infnlns@gmail.com
Methods 9 Ways of steering the simulation Hard coded Batch Interactive softwareschool.infnlns@gmail.com
Methods 10 Ways of steering the simulation Hard coded Batch No user interaction Everything specified in C++ source Re-compile needed to apply changes - - - Interactive softwareschool.infnlns@gmail.com
Methods 11 Ways of steering the simulation Hard coded Batch - Commands in external macro file Interactive softwareschool.infnlns@gmail.com
Methods 12 Ways of steering the simulation Hard coded Batch Interactive - Real time command input by user Textual, graphical (network-based) - softwareschool.infnlns@gmail.com
Methods 13 Ways of steering the simulation Hard coded Batch Interactive - Real time command input by user Textual, graphical (network-based) - softwareschool.infnlns@gmail.com
Method 1: Hard coded C++ /run/beamOn Must initialise and start the run by Number of events must be specified softwareschool.infnlns@gmail.com
Method 2: Batch session This example gets the file name of the macro from the command-line argument ./myApplication my- macro.mac softwareschool.infnlns@gmail.com
Method 3: Interactive session Commands processed one-by-one through G4 User Interface session (many different types inheriting from G4UIsession class Qt-GUI GAG-GUI (java based) Interfaces: Xm-GUI (motif based) C-shell (tsch, csh) Concrete UI session Class enabling selection of appropriate session at runtime based on environmental variables (recommended) G4UIQt session G4UIExecutive softwareschool.infnlns@gmail.com
Method 3: Interactive session Concrete UI session softwareschool.infnlns@gmail.com
Method 3: Interactive session G4UIQt session Visualisaiton softwareschool.infnlns@gmail.com
Method 3: Interactive session G4UIExecutive softwareschool.infnlns@gmail.com
Universal approach Batch/interactive (based on application argument) No argument -> interactive mode One argument -> batch mode ??? softwareschool.infnlns@gmail.com
Executing macros ASCII file containing UI commands Macro files can be executed: exampleB1.mac # comment line Interactively /control/execute macro_filename Batch session Command inputted in macro file Hard coded softwareschool.infnlns@gmail.com
Thank you softwareschool.infnlns@gmail.com
Tasks to do: Exercise 0.1: Find and understand the GEANT4 environment file Exercise 0.2: Check your Geant4 environment Exercise 0.3: compile and run the basic example B1 http://geant4.lngs.infn.it/belgrade2019/introduction /index.html softwareschool.infnlns@gmail.com
