Class InMemoryCoordinator<MASTER_RESULT extends Bytable,WORKER_RESULT extends Bytable>

java.lang.Object

ml.shifu.guagua.InMemoryCoordinator<MASTER_RESULT,WORKER_RESULT>

Type Parameters:

MASTER_RESULT - master computation result in each iteration.

WORKER_RESULT - worker computation result in each iteration.

public class InMemoryCoordinator<MASTER_RESULT extends Bytable,WORKER_RESULT extends Bytable>
extends Object

InMemoryCoordinator is a helper for in-memory master and worker coordination.

Master result can be set from master by signalWorkers(int, Bytable). Workers can get the result by getMasterResult().

Worker results can be set from worker by signalWorkers(int, Bytable). Master can get the result by getWorkerResults().
