Interface Optimizer<W extends Workload>

All Known Implementing Classes:

BasicOptimizer, BasicTHOptimizer, RealOptimizer, SuperOptimizer, SuperSpotTHOptimizer, SuperTHOptimizer

public interface Optimizer<W extends Workload>

This interface is used to for the implementations of the different scheduling options, the optimizer is presented a number of workloads associated with a certain workload model and instance specification. The workloads can be added using the add method, afterwards the determineOptimal method is called, which will schedule the workloads across a number of needed instances in a way that tries to minimize the total cost price of running the load on EC2.

Method Summary

void	add(W wl) Add the provided workload to the scheduling optimizer.
java.util.List<ScheduledTaskCollection>	determineOptimal()

Method Detail

add

void add(W wl)

Add the provided workload to the scheduling optimizer.

Parameters:

wl - the workload to add.

determineOptimal

java.util.List<ScheduledTaskCollection> determineOptimal()

Returns:

a list of scheduledTaskCollections, one of these represents the schedule containing subTasks for a single instance. This schedules are made in a way that tries to minimize the total cost of running the workload on EC2.
