Method Detail

map

public void map()

Description copied from class: Algo

Mapping function.

Specified by:

map in class Algo

replaceNode

public GNode replaceNode(GNode _dead,
                         java.util.ArrayList<GNode> _ag)

Description copied from class: Algo

Replace a fallen node by a new one, according to the mapping policy.

Specified by:

replaceNode in class Algo

Parameters:

_dead - The fallen node to be replaced

_ag - The list of all available computing nodes

Returns:

The new node

getOtherGNode

public GNode getOtherGNode(java.util.ArrayList<GNode> _ag)

Description copied from class: Algo

Find a new node, which may not takes part into the computation process. Typically such kind of node is used to create a new spawner or a new super-node, in order to bring fault tolerance.

Specified by:

getOtherGNode in class Algo

Returns:

Another node which will not compute
