This example is the distributed version of the app_task_farm example of the Simjava package -- a simulation of a simple work farm. The farmer sends out jobs to the three worker CPUs. When a CPU is busy with a job its work router (seen above it) passes new jobs on to the next CPU instead. If all the CPUs are busy then job will pass through all the routers and into the waste bucket. After a CPU finishes processing a job, it passes the result down to the work bucket, and signals its work router that it is free for more work. This example is composed of the following Java source files:

• Bucket.java - The Bucket entity.
• Farmer.java - The Farmer entity.
• RRouter.java - The RRouter entity.
• WRouter.java - The WRouter entity.
• Worker.java - The Worker entity.
• MainApplet.java - The main applet: creates Sim_system and Sim_anim objects and binds them in the RMI registry. This applet also controls the animation.
• Applet1.java - Applet with some of the simulation's entities.
• Applet2.java - Applet with the remaining simulation entities.

To Run:

1. Download and install the Distributed Simjava Software.

2. Start the rmiregistry on the machine where the Main applet will be run.

3. Ensure that the http daemon is running on the machine that contains the html files.

4. Start the Main applet by executing the command
   appletviewer http://url
   where url is the location of the file main.html

5. Start Applet1 by executing the command
   appletviewer http://url
   where url is the location of the file applet1.html

6. Start Applet2 by executing the command
   appletviewer http://url
   where url is the location of the file applet2.html
