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))))
