Description

It returns a list of 3 elements, where the first element is a list of partitions, the second is a list of row indices, and third a a list of column indices.

Usage

getPartitionIdsAndOffsets(indices, psizes, nparts)

Arguments

indices

A sorted list of sorted vectors, where the first element are the row indices, and the second (if 2d), column indices.

psizes

Partition-sizes matrix of the distributed object.

nparts

nparts vector of the distributed object.
