DCSim

A Data Centre Simulation Tool for Evaluating Dynamic Virtualized Resource Management

Simulator Code

  • The core simulation code is located in the src/ directory

Traces

  • A set of trace files to use with the simulator are located in the traces/ directory
  • Trace files are csv files, with each line containing the pair [time, value]
    • Time is simulation time in ms
    • Value is a normalized load value in the range [0, 1], where 0 represents 0 load, and 1 represents the largest load in the trace

Configuration

  • The config/simulation.config file contains a set of configuration parameters to configure host and VM state transition delays (i.e. for powering on and off, starting a VM), migration penalty and overhead values, and simulation output. You can also choose to use an approximate MVA calculation for VM queuing model calculation, to improve simulation performance (recommended).

Examples

  • The examples/ directory contains a set of basic examples of how to use the simulator
  • SimpleExample is a good starting point to using the simulator. You can run this file directly, and read the code for a basic introduction

Configuring and Using the Simulator

  • A particular simulation configuration and setup is defined by extending SimulationTask, and overriding its setup() method. Within this method, configure your simulation (see examples in the example/ directory)
  • Run your simulation by creating a new instance of your SimulationTask, and calling its run() method.
  • You must call Simulation.initializeLogging() prior to creating and running your SimulationTask
  • You can get the results of your simulation from SimulationTask.getMetrics()
