Brn.Gui
The Brn.Gui is a user interface for the Brn.Sim simulator. It is able to control the simulation execution like a debugger. It visualizes simulation results which are specified in simulation code via the Brn.Measure framework. Furthermore, it is also a result browser for already completed simulations which were executed by the Brn.DistSim distributed simulation framework and stored in the Brn.Db storage. For details see Brn.Gui

Brn.Db and Brn.DistSim
DistSim is a framework for defining, executing and collecting the results of multiple similar simulations. Core component is the Wrapper, which obtains simulation definitions from a database and executes it. Furthermore, there are JMX Mbeans for the distributed management of wrapper instances.
Steps to start the distsim framework
- Check out the wrapper from [1]
- Build and run via "ant run-jmx". Remember to set an unused RMI Registry port with "-Dbrn.distsim.jmxremote.port=xxxxx". If you want to access the HTTP console, specify an unused port via "-Dbrn.distsim.jmxremote.http.port=xxxx".
- Access the Brn.DistsimManager via HTTP or another JMX Client (JConsole, JMX Eclipse Plugin, VisualVM). In the Agent View, you will see the Distsim manager and the Wrapper manager within the context brn.distsim.jmx.
- Now, you are able to set up a federated Brn.Distsim service. Simply start another Brn.Distsim on a remote computer. Go to the local Distsim manager and execute the operation addDistsim. If the operation succeeds, you will see the Distsim manager within the property ActiveDistsims of the local Distsim manager. Be careful not to create loops; the result will be undefined.
- To start wrappers, go to the Distsim manager MBean and invoke the operation "startWrapper". Specify the database connection information, the host to start wrappers on (with optional ":port"), the first id to use with the wrappers (idStart) and the number of wrappers to start on this node (number).
- To start wrappers on multiple hosts simultaneously, use the operation "startWrapperAll". The parameter "startString" must be an enumeration of the form 'host[:port] idStart:number'.
- Use the operation "stopWrapper" or "stopWrapperAll" to stop the wrapper after a simulation run.
- The federated service is shut down via "stopDistsimAll".
