Class SuperOptimizer

java.lang.Object
  be.ac.ua.broker.scheduling.workload.wm2.SuperOptimizer

All Implemented Interfaces:

Optimizer<WorkloadWM2>

public class SuperOptimizer
extends java.lang.Object
implements Optimizer<WorkloadWM2>

This class is used to perform the optimized/spot-optimized scheduling for workload model two tasks. The RealOptimizer is used to perform the scheduling within a bucket. The tasks are evenly distributed across buckets, to make the algorithm feasible.

Constructor Detail

SuperOptimizer

public SuperOptimizer(java.util.Date startDate,
                      InstanceSpecification spec,
                      boolean use_spot_optimalization)

Constructor for SuperOptimizer

Parameters:

startDate - start time of the scheduling period

spec - specification of the instance for which a schedule is created

use_spot_optimalization - whether the spot-optimized scheduling option is set

Method Detail

add

public void add(WorkloadWM2 wl)

Description copied from interface: Optimizer

Add the provided workload to the scheduling optimizer.

Specified by:

add in interface Optimizer<WorkloadWM2>

Parameters:

wl - the workload to add.

determineOptimal

public java.util.List<ScheduledTaskCollection> determineOptimal()

Specified by:

determineOptimal in interface Optimizer<WorkloadWM2>

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.

getIntervalLength

public int getIntervalLength()

Returns:

the length of a single interval/bucket in hours
