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
OutScalardetermines the output scalar type
LhsScalardetermines the left-hand-side scalar type
RhsScalardetermines the right-hand-side scalar type
OutAccessordetermines 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)
LhsMapperdetermines the tensor contraction mapper type for left-hand-side matrix
RhsMapperdetermines the tensor contraction mapper type for right-hand-side matrix
StorageIndexdetermines the StorageIndex Type
Vectorizabledetermines whether or not the vectorization is enabled for the Eigen expression.
Parameters
scratchlocal memory containing tiles of LHS and RHS tensors for each work-group
lhsdetermines the left-hand-side flattened tensor (tensor mapper)
rhsdetermines the right-hand-side flattened tensor (tensor mapper)
out_resdetermines the output tensor containing the contraction result
rngdetermins the total input data size
