Class Default

java.lang.Object
  extended by nenok.lc.alloc.Default
All Implemented Interfaces:
Allocator

public class Default
extends Object
implements Allocator

This is a default implementation of a dynamic processor allocation model. To determine the processor to allocation to a given node, this model only considers the allocation of the node's parents.

public Default(Processor proc)
Constructor:

Parameters:
proc - The processor that is allocated to leaf nodes.
Method Detail

allocate

public void allocate(Node node)
              throws RemoteException
Description copied from interface: Allocator
Dynamic allocation procedure. Allocates a processor to the node given as argument. This method is called from the collect algorithm for each node strictly before any computations are executed onto this node. Note: Static allocation is not possible with this method. To do so, we recomment to implement a corresponding constructor and to provide an empty implementation of this method.

Specified by:
allocate in interface Allocator
Parameters:
node - The current node to which a processor needs to be allocated.
Throws:
RemoteException - Communication exception caused by accessing processors.

getName

public String getName()
Specified by:
getName in interface Allocator
Returns:
The name of this processor allocation model.

Allocator.getName()

totalCosts

public int totalCosts()
Specified by:
totalCosts in interface Allocator
Returns:
Returns the total communication costs caused so far.
