All Implemented Interfaces:

Cloneable, Runnable

public class ARGridResource
extends GridResource

ARGridResource class handles all Advanced Reservation functionalities. All the functionalities are done by its internal or private methods.
NOTE: It is important to set the allocation policy inside ResourceCharacteristics object into ResourceCharacteristics.ADVANCE_RESERVATION. In addition, a resource's scheduler should be extending from ARPolicy class.

Since:

GridSim Toolkit 3.0

Constructor Detail

ARGridResource

public ARGridResource(String name,
                      double baud_rate,
                      ResourceCharacteristics resource,
                      ResourceCalendar calendar,
                      ARPolicy policy)
               throws Exception

Allocates a new GridResource object that supports Advanced Reservation.

Parameters:

name - the name to be associated with this entity (as required by Sim_entity class from simjava package)

baud_rate - network communication or bandwidth speed

resource - an object of ResourceCharacteristics

calendar - an object of ResourceCalendar

policy - a scheduler for this Grid resource. The scheduler should be able to handle Advanced Reservations.

Throws:

Exception - This happens when one of the following scenarios occur:

• creating this entity before initializing GridSim package
• this entity name is null or empty
• this entity has zero number of PEs (Processing Elements).
  No PEs mean the Gridlets can't be processed. A GridResource must contain one or more Machines. A Machine must contain one or more PEs.

Pre Condition:

$none

Post Condition:

$none

ARGridResource

public ARGridResource(String name,
                      Link link,
                      ResourceCharacteristics resource,
                      ResourceCalendar calendar,
                      ARPolicy policy)
               throws Exception

Allocates a new GridResource object that supports Advanced Reservation.

Parameters:

name - the name to be associated with this entity (as required by Sim_entity class from simjava package)

link - the link that will be used to connect this ARGridResource to another Entity or Router.

resource - an object of ResourceCharacteristics

calendar - an object of ResourceCalendar

policy - a scheduler for this Grid resource. The scheduler should be able to handle Advanced Reservations.

Throws:

Exception - This happens when one of the following scenarios occur:

• creating this entity before initializing GridSim package
• this entity name is null or empty
• this entity has zero number of PEs (Processing Elements).
  No PEs mean the Gridlets can't be processed. A GridResource must contain one or more Machines. A Machine must contain one or more PEs.

Overrides:

processOtherEvent in class GridResource

Parameters:

ev - a Sim_event object

Pre Condition:

ev != null

Post Condition:

$none
