Installing and Running the C++ version

Once downloaded, follow these instructions to get BRITE up and running.

1. Unzip the downloaded file:

   $ gunzip BRITE_CPP.tar.gz
   $ tar xvf BRITE_CPP.tar
   

2. Directory structure of C++ version

   The contents of the directory where the C++ version is untarred is shown in Table 8.

   
   

   Table 8: Contents of C++ version's directory

   Directory/File	Contents
   Models/	Source files for all supported models
   Util.h, Util.cc	Utility functions
   Topology.h, Topology.cc	Topology class
   Graph.h, Graph.cc	Graph class
   Node.h, Node.cc	Node class (graph)
   Edge.h, Edge.cc	Edge class (graph)
   Parse.h, Parse.cc	Parsing class
   BriteMain.cc	Entry point
   conf_files/	Sample configuration files
   Makefile	Makefile

   
   

3. Change to the directory created when the C++ distribution file is untarred. Assuming it is called BRITE, we change to that directory and compile:

   $ cd BRITE
   $ make c++
   

4. Running BRITE from the GUI (Java is required since the GUI is implemented in Java):

    
   $ startGUI
   

5. Running BRITE from the command line (No Java required):

   $ cd C++
   $ brite <config_file.conf>  <output_file> <seed_file>
   

The C++ version uses a seed file to seed all the random variables used during the generation process. The specific seed file to be used must be specified as an argument to BRITE. Every time that BRITE runs, it saves the current seed file into a backup file named last_seed_file. Having the seed file saved, allows the user to reproduce the behavior of the generator on the last run, by copying last_seed_file to seed_file and repeating the execution with the same configuration file.
