This example is the distributed version of the MVS example. Due to the total execution time, this example only sends 1000 jobs through the MVS system. The example is composed of the following Java source files:

• JobIF.java -- RMI interface allowing remote access to the data stored in a Job instance.
• StatsClassIF.java -- RMI interface allowing remote access to the data stored in StatsClass.
• ServerIF.java -- RMI interface allowing remote access to data local to a server.
• Sim_expon_obj.java -- An exponentially distributed random number generator.
• mvs.java -- Contains the following classes:
  1. Job -- A user-defined object that gets passes through the MVS system via simjava events.
  2. reportFileClass -- Prints out the results of the simulation to a report file.
  3. StatsClass -- Used to compute system-level statistics.
  4. Termination -- Generates the final report.
  5. Server -- Contains the behavior of the servers.
  6. Source -- Contains the behavior of the sources.
  7. Sink -- Contains the behavior of the sink.
• Master.java -- The Master program that:
  1. Creates an instance of the Sim_system and binds it in the RMI registry.
  2. Creates an instance of the StatsClass and binds it in the RMI registry.
  3. Creates an instance of the Termination class.
• MVSServers.java -- Creates the server instances (jess, cpu1, cpu2, prt).
• MVSSink.java -- Creates the MVS system sink.
• MVSSources.java -- Creates the source instances (m300, m1200, m2400, l9600).

To Run:

1. Download and install the Distributed Simjava Software.

2. Start the rmiregistry on the machine where the Master program will be run.

3. Start the Master program by executing the command
   java Master registryHost registryPort #Entities
   where
   • registryHost is the name of the machine where the RMI registry has been started
   • registryPort is the port that the RMI registry is listening to
   • #Entities is the number of expected entities (10 for this example)

4. Start the MVS Sources by executing the command
   java MVSSources registryHost registryPort
   where
   • registryHost is the name of the machine where the RMI registry has been started
   • registryPort is the port that the RMI registry is listening to

5. Start the MVS Servers by executing the command
   java MVSServers registryHost registryPort
   where
   • registryHost is the name of the machine where the RMI registry has been started
   • registryPort is the port that the RMI registry is listening to

6. Start the MVS Sink by executing the command
   java MVSServers registryHost registryPort
   where
   • registryHost is the name of the machine where the RMI registry has been started
   • registryPort is the port that the RMI registry is listening to
