17th Fluka Course, Munich, Germany

# Requirements

Prior to the course we encourage you having a certain 'basic' knowledge of Linux. Below you'll find a first selection of useful/needed commands and for those of you still feeling a bit uneasy with the use of Linux, we kindly ask you to have a closer look, as well as possibly follow related Linux tutorials which are available on the network: Linux tutorial

Furthermore, those of you bringing their own laptop are kindly requested to verify the proper functioning of FLUKA & FLAIR, at least in terms of software requirements (gcc, Python, gnuplot, etc...).

### Chapter 1: Hardware and Software requirements:

For the moment FLUKA does not support Windows and Mac, thus even though one could envisage running through X-window connections (such as Exceed, Putty, VNC,...) we do not encourage doing so for the course. Course participants intending to use their own laptop need a working LINUX system installed. We encourage everybody to check if their LINUX system contains all elements listed below, as well as their correct functioning:

 required package version required how to verify? (type in terminal) Fortran g77/gcc or gfortran/gcc 3.0 or higher 4.6 or higher g77 -v gfortran -dumpversion  Python (with Tkinter and Tk/Tcl) Python: 2.3 or higher (but not V3.+) Tk/Tcl: 8.3 or higher Python: python -V Tkinter: type: python in terminal and then type: import Tkinter If you get error messages you don't have Tkinter installed. Type Ctrl-D to exit the python interpreter. For the interactive geometry visualization python-devel tk-devel Depending on the distribution can have the names python-dev, python-devel, tk-dev, tk-devel, tk-dev85 etc.. gnuplot 4.0 or higher (4.2 or higher recommended) Type: gnuplot -V on the command line. This will print the gnuplot version. PDF reader Anything which reads PDF files (Acrobat Reader, xpfd, kpdf etc.)

### Chapter 2: Computing skills (LINUX) required for the FLUKA course:

In the course LINUX will be used as operating system and we strongly encourage that you are familiar with the main basic shell commands - ideally already before the course.

#### The following is needed for the course:

• opening a terminal (depends on your distribution, on most systems there is an icon on the Desktop or in the taskbar of the desktop environment, or it can be found somewhere in the start menu)
• being able to work with a text editor (Emacs, nedit, gedit, kate, vim, vi, joe etc.) to create, edit and save files

#### Knowledge of the following Linux commands:

 command meaning syntax cat list the contents of short files to the screen cat  cd change the current working directory cd  starting from root directory: cd /home move to parent directory: cd .. move to user directory: cd ~ cp copy the file; will overwrite destination if exists cp  prompt before overwrite: cp -i  copy file to current directory: cp . copy whole directory and all its contents: cp -r  grep search for a string in file(s) grep  search recursively in whole directory: grep -r  example: grep "fluka" report.txt less displays the contents of the file (user can scroll up/down) less  ls list files ls list all files with a lot of info: ls -al man get detailed information how to use particular command; press SHIFT+Z twice to exit man  mkdir create a directory mkdir  mv move or rename file mv  pwd show the name of the current working directory rm remove command removes a file: rm  removes all files in current directory except subdirs: rm * removes directory with all its contents: rm -r rmdir remove dir if empty rmdir  tar tool for (de)compress file(s) example: tar -xvf archive.tar tar -xzf archive.tar.gz to create an archive from directory: tar -czf archive.tar.gz  touch create file touch

#### Environment variables:

Environment variables are 'placeholders' used in the shell holding 'strings'. In this course we will use them to set the variable FLUPRO which defines the path to the directory where FLUKA is installed. Depending on the shell used (bash, tcsh ...) one has to use different commands setenv or export. To access the name of the variable one has to put a $in front of the name,$FLUPRO in this case. An example:
on tcsh:

setenv FLUPRO /path/to/FLUKA

on bash:
export FLUPRO=/path/to/FLUKA

To see if the variable is set correctly set one can print its content by:
echo \$FLUPRO
This should print /path/to/FLUKA
