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) <EOF>

  • Header():

  • <HDR> ("\n" | "\r") <NUM>+ ("\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!!!!
