public class ParallelResource
extends GridResource

ParallelResource extends the GridResource class for gaining communication and concurrent entity capabilities. An instance of this class simulates a resource with properties defined in an object of ResourceCharacteristics class to maintain compatible with GridSim.

To create a parallel resource consists you need a list of machines with PEs (Processing Element) with a suitable MIPS (Million Instructions Per Second) or SPEC (Standard Performance Evaluation Corporation) rating;

NOTE THAT:

• The list of machines comprising this resource must be homogeneous.
• A resource local load is not considered, a resource calendar will not be available for the allocation policy.
• If you would like to simulate the local load, you have to model the local load as jobs submitted by a user. It is more precise and faster. To do so, please check WorkloadLublin99.

Constructor Detail

ParallelResource

public ParallelResource(String name,
                        double baud_rate,
                        ResourceCharacteristics resource,
                        AllocPolicy policy)
                 throws Exception

Allocates a new object. When making a different type of resource object, use this constructor and then override processOtherEvent(Sim_event).

Parameters:

name - the name to be associated with this entity

baud_rate - network communication or bandwidth speed

resource - an object of ResourceCharacteristics

policy - a scheduling policy for this resource. If no scheduling policy is defined, the default one is SpaceShared

Throws:

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

• creating this entity before initialising GridSim package
• this entity name is null or empty
• this entity has zero number of PEs (Processing Elements).

See Also:

GridSim.init(int, Calendar, boolean, String[], String[], String), GridSim.init(int, Calendar, boolean), AllocPolicy

Pre Condition:

name != null, baud_rate > 0, resource != null, calendar != null, policy != null

Post Condition:

$none

ParallelResource

public ParallelResource(String name,
                        Link link,
                        ResourceCharacteristics resource,
                        AllocPolicy policy)
                 throws Exception

Allocates a new object. When making a different type of resource object, use this constructor and then overrides processOtherEvent(Sim_event).

Parameters:

name - the name to be associated with this entity

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

resource - an object of ResourceCharacteristics

policy - a scheduling policy for this Grid resource. If no scheduling policy is defined, the default one is SpaceShared

Throws:

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

• creating this entity before initialising GridSim package
• this entity name is null or empty
• this entity has zero number of PEs (Processing Elements).

GridSim.init(int, Calendar, boolean, String[], String[], String), AllocPolicy

Pre Condition:

name != null, link != null, resource != null, calendar != null, policy != null

Post Condition:

$none
