Public Attributes
const index< 3 >	global
	An index of rank 1, 2, or 3 that represents the global index within an extent.
const index< 3 >	local
	An index of rank 1, 2, or 3 that represents the relative index within the current tile of a tiled extent.
const index< 3 >	tile
	An index of rank 1, 2, or 3 that represents the coordinates of the current tile of a tiled extent.
const index< 3 >	tile_origin
	An index of rank 1, 2, or 3 that represents the global coordinates of the origin of the current tile within a tiled extent.

	An object which represents a barrier within the current tile of threads.

Static Public Attributes
static const int	rank = 3
	A static member of tiled_index that contains the rank of this tiled extent, and is either 1, 2, or 3 depending on the specialization used.

Detailed Description

template<int D0, int D1 = 0, int D2 = 0>
class Concurrency::tiled_index< D0, D1, D2 >

Represents a set of related indices subdivided into 1-, 2-, or 3-dimensional tiles.

Template Parameters

D0,D1,D2

The length of the tile in each specified dimension, where D0 is the most-significant dimension and D2 is the least-significant.

Constructor & Destructor Documentation

template<int D0, int D1 = 0, int D2 = 0>

Concurrency::tiled_index< D0, D1, D2 >::tiled_index ( const tiled_index< D0, D1, D2 > &  o )

inline

Copy constructor.

Constructs a new tiled_index from the supplied argument "other".

Parameters

[in]

other

An object of type tiled_index from which to initialize this.

Member Function Documentation

template<int D0, int D1 = 0, int D2 = 0>

Concurrency::extent<3> Concurrency::tiled_index< D0, D1, D2 >::get_tile_extent ( ) const

inline

Returns an instance of an extent<N> that captures the values of the tiled_index template arguments D0, D1, and D2.

For example:

index<3> zero;
tiled_index<64,16,4> ti(index<3>(256,256,256), zero, zero, zero, mybarrier);
extent<3> myTileExtent = ti.tile_extent;
assert(myTileExtent.tile_dim0 == 64);
assert(myTileExtent.tile_dim1 == 16);
assert(myTileExtent.tile_dim2 == 4);

template<int D0, int D1 = 0, int D2 = 0>

Concurrency::tiled_index< D0, D1, D2 >::operator const index< 3 > ( ) const

inline

Implicit conversion operator that converts a tiled_index<D0,D1,D2> into an index<N>.

The implicit conversion converts to the .global index member.

const Concurrency::extent<3> Concurrency::tiled_index< D0, D1, D2 >::tile_extent

Returns an instance of an extent<N> that captures the values of the tiled_index template arguments D0, D1, and D2.

For example:

index<3> zero;
tiled_index<64,16,4> ti(index<3>(256,256,256), zero, zero, zero, mybarrier);
extent<3> myTileExtent = ti.tile_extent;
assert(myTileExtent.tile_dim0 == 64);
assert(myTileExtent.tile_dim1 == 16);
assert(myTileExtent.tile_dim2 == 4);
