Detailed Description

View that maps element ids to partition ids.

Function Documentation

partitioning_view()

template<typename MappingView , typename GIDDomain , typename PartitioningFunction >

distribution_spec_view<MappingView, GIDDomain, typename GIDDomain::index_type, typename MappingView::index_type> stapl::partitioning_view	(	MappingView &	mapping_view,
		GIDDomain const &	domain,
		PartitioningFunction const &	partitioning_func
	)

Creates a read-only view whose domain is the identifiers of a container's elements and whose mapping function maps from element GID to partition id.

When the partitioning_view is defined over a mapping_view the result is a view which defines the distribution of container elements across the locations of the system.

Parameters

mapping_view	view that will map the partition ids to locations
domain	Set of element GIDs to be partitioned.
partitioning_func	Unary functor that receives a GID and returns a partition id.

Returns

A view capable of partitioning GIDs of container elements.
