    Subclasses of DataPartitionLocalScheme in org.apache.sysds.runtime.controlprogram.paramserv.dp
    Modifier and Type | Class and Description
    --- | ---
    `class` | `DCLocalScheme` Disjoint_Contiguous data partitioner: for each worker, use a right indexing operation X[beg:end,] to obtain contiguous, non-overlapping partitions of rows.
    `class` | `DRLocalScheme` Data partitioner Disjoint_Random: for each worker, use a permutation multiply P[beg:end,] %*% X, where P is constructed for example with P=table(seq(1,nrow(X)),sample(nrow(X), nrow(X))), i.e., sampling without replacement to ensure disjointness.
    `class` | `DRRLocalScheme` Disjoint_Round_Robin data partitioner: for each worker, use a permutation multiply or simpler a removeEmpty such as removeEmpty (target=X, margin=rows, select=(seq(1,nrow(X))%%k)==id)
    `class` | `ORLocalScheme` Data partitioner Overlap_Reshuffle: for each worker, use a new permutation multiply P %*% X, where P is constructed for example with P=table(seq(1,nrow(X),sample(nrow(X), nrow(X))))
