public class UaggOuterChainSPInstruction
extends BinarySPInstruction

Two types of broadcast variables used -- 1. Array of type double. 2.PartitionedMatrixBlock 1. Array of type double: Matrix B is sorted at driver level and passed to every task for cases where operations are handled with special cases. e.g. <, RowSum 2. PartitionedMatrixBlock: Any operations not implemented through this change goes through generic process, In that case, task takes Matrix B, in partitioned form and operate on it.
