Detailed Description

template<typename Policy>
struct flecsi::topo::narray< Policy >

Narray Topology.

Colors are assigned lexicographically; the first dimension varies fastest.

Template Parameters

Policy the specialization, following narray_specialization.

Member Function Documentation

template<typename Policy >

static void idx_itvls	(	index_definition const &	idef,
		std::vector< std::size_t > &	num_intervals,

staticprivate

Method to compute the local ghost "intervals" and "points" which store map of local ghost offset to remote/shared offset.

This method is called by the "make_copy_plan" method in the derived topology to create the copy plan objects.

Parameters

	idef	index definition
[out]	num_intervals	vector of number of ghost intervals, over all colors, this vector is assumed to be sized correctly (all colors)
[out]	intervals	vector of local ghost intervals, over process colors
[out]	points	vector of maps storing (local ghost offset, remote shared offset) for a shared color, over process colors

private

Method to create copy plans for entities of an index-space.

Parameters

colors	The number of colors
