US Patent 9507568 Nested communication operator

A high level programming language provides a nested communication operator that partitions a computational space. An indexable type with a rank and element type defines the computational space. The nested communication operator partitions a specified dimension of an index indexable type into segments specified by a segmentation vector and returns an output indexable type that represents the segments. By doing so, the nested communication operator allows data parallel algorithms to operate on the segments as individual units.
