#include <unsupported/Eigen/CXX11/src/Tensor/TensorContractionSycl.h>

Detailed Description

template<typename OutScalar, typename LhsScalar, typename RhsScalar, typename OutAccessor, typename LhsMapper, typename RhsMapper, typename StorageIndex, bool Vectorizable>
struct Eigen::TensorSycl::internal::GeneralScalarContraction< OutScalar, LhsScalar, RhsScalar, OutAccessor, LhsMapper, RhsMapper, StorageIndex, Vectorizable >

GeneralScalarContraction is a template class that provides the scalar value of Tensor -Tensor contraction operation, when all the dimensions are contracting dimensions. This Kernel reduces two tensors to an scalar.

Template Parameters

OutScalar	determines the output scalar type
LhsScalar	determines the left-hand-side scalar type
RhsScalar	determines the right-hand-side scalar type
OutAccessor	determines the sycl accessor type for out put (please see the sycl-1.2.1 specification (https://www.khronos.org/registry/SYCL/specs/sycl-1.2.1.pdf) for accessor definition)
LhsMapper	determines the tensor contraction mapper type for left-hand-side matrix
RhsMapper	determines the tensor contraction mapper type for right-hand-side matrix
StorageIndex	determines the StorageIndex Type
Vectorizable	determines whether or not the vectorization is enabled for the Eigen expression.

Parameters

scratch	local memory containing tiles of LHS and RHS tensors for each work-group
lhs	determines the left-hand-side flattened tensor (tensor mapper)
rhs	determines the right-hand-side flattened tensor (tensor mapper)
out_res	determines the output tensor containing the contraction result
rng	determines the total input data size
