CSE 132 (Spring 2015)
Lab 3c: HaWUp Visualizer

Overview

• How many nodes are present on the HaWUp instance?
• For each Node, is it busy or idle?
• How many tasks are waiting in each Node's queue?

Instructions

1. Update your repository to get the latest of any software pushed to you.
2. Look at the hawup.examples subpackages: sleeps, sum, and Hack. The Main class in each of those examples launches both the HaWUPp instance and the HaWUpViz visualizer. That visualizer currently doesn't do anything, but it has both a default constructor (used by WindowBuilder) and a constructor appropriate to an actual HaWUp instance.
3. To create the visualizer, make note of the messages issued from Nodes. The messages from Tasks may also be of interest.

   The visualizer shown in class was based on GridLayout, which divides the screen into a fixed number of rows and columns. The nice thing about that layout is that the grid's boxes expand and shrink with the window size.

   Review the Video Demo to see that visualization.
