Class TaskGenerator

java.lang.Object
  be.ac.ua.broker.input.tasks.generation.wm2.TaskGenerator

public class TaskGenerator
extends java.lang.Object

This class is used to generate a workload model two task that uses the specification provided using the program arguments. A possible program argument array is: 'task1 descr "Micro - Micro" "EU - Ireland" "Linux/Unix" "2011-11-11 00:00" 3600 workload1 false'. We first provide a desired name and description for the task, followed by information about the instance the task has to run on: the instance type, the geographical region and the operating system. We also provide the deadline of the task, the length of the task in hours, a name associated with the randomly generated workload created for the task and whether or not the task is allowed to be run on spot instances.

Method Detail

main

public static void main(java.lang.String[] args)

The TaskGenerator is used to generate task description files of tasks that use workload model two. A possible program argument array is: 'task1 descr "Micro - Micro" "EU - Ireland" "Linux/Unix" "2011-11-11 00:00" 3600 workload1 false'. We first provide a desired name and description for the task, followed by information about the instance the task has to run on: the instance type, the geographical region and the operating system. We also provide the deadline of the task, the length of the task in hours, a name associated with the randomly generated workload created for the task and whether or not the task is allowed to be run on spot instances.

Parameters:

args - program arguments

getArrayDescription

public java.lang.String[] getArrayDescription()

Returns:

an array description of the generated task
