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()
