Detailed Description

template<class DataScalar, typename DeviceType>
class Intrepid2::Data< DataScalar, DeviceType >

Wrapper around a Kokkos::View that allows data that is constant or repeating in various logical dimensions to be stored just once, while providing a similar interface to that of View.

The Data class distinguishes between the logical extent and the data extent. For example, one could construct a data container corresponding to constant (cell, point) data with 100 cells and 25 points per cell as follows: auto cpData = Data(value, Kokkos::Array<int>{100,25}); The data extent of the container is 1 in every dimension, while the logical extent is 100 in the first dimension, and 25 in the second. Similarly, the logical rank of the container is 2, but the rank of the underlying View is 1.

There are four possible variation types in a logical dimension:

GENERAL: the data varies arbitrarily. The underlying View will have the same extent in its corresponding dimension (which may be distinct from the logical dimension).
CONSTANT: the data does not vary. The underlying View will not have a dimension corresponding to this dimension.
MODULAR: the data varies with a modulus. The underlying View will have a corresponding dimension with extent corresponding to the modulus.
BLOCK_PLUS_DIAGONAL: the data varies in this logical dimension and one other, corresponding to a square matrix that has some (possibly trivial) full block, with diagonal entries in the remaining dimensions. The underlying View will have one dimension corresponding to the two logical dimensions, with extent corresponding to the number of nonzeros in the matrix.

Variation modulus accessor.

Parameters

[in] d - the logical dimension whose variation modulus is requested.

Returns: the variation modulus.

The variation modulus is defined as the number of unique entries in the specified dimension. This is defined as follows:

for CONSTANT variation, the variation modulus is 1
for MODULAR variation, the variation modulus is exactly the modulus by which the data repeats in the specified dimension
for GENERAL variation, the variation modulus is the extent in the specified dimension
for BLOCK_PLUS_DIAGONAL, the variation modulus in the first logical dimension of the matrix is the number of nonzeros in the matrix; in the second logical dimension the variation modulus is 1.

[in]	d	- the logical dimension in which the extent is to be changed
[in]	newExtent	- the new extent

Note: Not supported for dimensions in which the variation type is BLOCK_PLUS_DIAGONAL.; If the variation type is MODULAR, the existing modulus must evenly divide the new extent; the underlying data structure will not be resized in this case.

template<class DataScalar, typename DeviceType>

void Intrepid2::Data< DataScalar, DeviceType >::storeMatMat	(	const bool	transposeA,
		const Data< DataScalar, DeviceType > &	A_MatData,
		const bool	transposeB,
		const Data< DataScalar, DeviceType > &	B_MatData
	)

inline

Places the result of a matrix-matrix multiply corresponding to the two provided containers into this Data container. This Data container should have been constructed by a call to allocateMatMatResult(), or should match such a container in underlying data extent and variation types.

See Also: allocateMatMat()

Parameters

A_MatData	[in] - logically (...,D1,D2)-dimensioned container, where D1,D2 correspond to matrix dimensions.
transposeA	[in] - if true, A will be transposed prior to being multiplied by B (or B's transpose).
B_MatData	[in] - logically (...,D3,D4)-dimensioned container, where D3,D4 correspond to matrix dimensions.
transposeB	[in] - if true, B will be transposed prior to the multiplication by A (or A's transpose).
