Package org.apache.sysds.runtime.controlprogram.parfor

Class ResultMergeMatrix

java.lang.Object

org.apache.sysds.runtime.controlprogram.parfor.ResultMerge<MatrixObject>

org.apache.sysds.runtime.controlprogram.parfor.ResultMergeMatrix

All Implemented Interfaces:

Serializable

Direct Known Subclasses:

ResultMergeLocalAutomatic, ResultMergeLocalFile, ResultMergeLocalMemory, ResultMergeRemoteSpark, ResultMergeRemoteSparkWCompare

public abstract class ResultMergeMatrix
extends ResultMerge<MatrixObject>

Due to independence of all iterations, any result has the following properties:

(1) non local var,

(2) matrix object, and

(3) completely independent.

These properties allow us to realize result merging in parallel without any synchronization.
