Class ComputeInstanceMapper

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

public class ComputeInstanceMapper
extends java.lang.Object

This class is used to read the mapping from Amazon EC2 supported instance type to the associated number of compute units. This number is used to create a workload load for every task hour of a workload model two task according to the ratios provided by these ECUs.
