Java Based Visualizer for BeoSim
Michael Bassily SURE 2004 Advisor Dr. Ligon
Visualizer Constructs

• Background
• What is BeoSim?

• New
• All Native java
• AWT and SWING
• Data structure at most the size of number of time
  stamps

New Visualizer Components

• OLD
• Used 3rd party graphic package JFreeChart
• Large data structure

• A mini-grid simulator -
• Mini-grid a collection of clusters
  limitedto campus wide setting
• Event Driven
• Used for testing of meta-scheduling algorithms
• Higher level distributed scheduling process,
  through which actions of all local schedules are
  coordinated on a grid wide bases, used for
  Co-allocation of clusters

Example Mini grid
The Data structure JobNode.java holds data
about each specific job TimeSlice.java holds
data about each time stamp TimeSack.java
holds data about the entire parse
GUI Interface
Co-allocation
The Parser BeoParse.jj Based on sun standard
compiler compiler JavaCC Based on regular
expressions, i.e. ("\n" "\r") Header()
Body(currentData) Footer(currentData)
ltEOFgt Header() ltHDRgt ("\n" "\r") ltNUMgt ("\n"
"\r")
Runtime Improvements
GUI Interface BeoVizGuie.java main frame
holder Sub files for each inner
frame ClusterFrame.java displays cluster
allocation information JobAllocFrame.java
displays timeline of running jobs QueueFrame.java
displays instantaneous and average
queue lengths StatsFrame.java
displays usage statistics such as
grid utilization percentage
Problem
Visualizer GUI Concept Figure
The output file of BeoSim can sometimes be
thousands of lines long, a way is needed so that
the user can easily see what is occurring at any
given time point, a Visualizer is needed!!! There
is also a previous Visualizer, but it is too slow.
The new Visualizer is much faster!!!!
