                              CheckpointStatus checkpointStatus)

Constructor.

Parameters:

numLocalVertices - Number of local vertices

allVerticesHalted - Are all the vertices halted

numVertices - Number of vertices

numEdges - Number of edges

mustLoadCheckpoint - Has to load a checkpoint?

checkpointStatus - Should we checkpoint after this superstep?

Method Detail

getLocalVertexCount

public long getLocalVertexCount()

allVerticesHalted

public boolean allVerticesHalted()

Are all the vertices halted?

Returns:

True if all halted, false otherwise

mustLoadCheckpoint

public boolean mustLoadCheckpoint()

Must load the checkpoint?

Returns:

True if the checkpoint must be loaded, false otherwise

getCheckpointStatus

public CheckpointStatus getCheckpointStatus()

What master thinks about checkpointing after this superstep.

Returns:

CheckpointStatus that reflects master decision.
