Detailed Description

template<typename OutScalar, typename OutAccessor, typename VectorMapper, typename TensorMapper, typename StorageIndex, typename Properties, StorageIndex KFactor, bool Vectorizable, bool is_lhs_vec, bool IsFinal>
struct Eigen::TensorSycl::internal::GeneralVectorTensor< OutScalar, OutAccessor, VectorMapper, TensorMapper, StorageIndex, Properties, KFactor, Vectorizable, is_lhs_vec, IsFinal >

GeneralVectorTensor is a template class that provides Tensor -vector contraction operation, which is a special case of Tensor Tensor contraction.

Template Parameters

OutScalar	determines the output 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)
VectorMapper	determines the tensor contraction mapper for the vector input (can be lhs or rhs)
TensorMapper	determines the tensor contraction mapper for the tensor input (can be lhs or rhs)
StorageIndex	determines the StorageIndex Type
Properties	determines the Contraction Panel properties
KFactor	determines the number of elements in K dimension in a Tile
Vectorizable	determines whether or not the vectorization is enabled for the Eigen expression.
is_lhs_vec	determines whether lhs is a vector or rhs is a vector
IsFinal	determine if this is the final kernel. If so, the result will be written in a final output. Otherwise, the result of contraction will be written iin a temporary buffer.

Parameters

scratch	determines the local memory containing the vector block for each work-group
vec	determines the vector input (tensor mapper)
mat	determines the tensor input (tensor mapper)
out_res	determines the output vector containing the contraction result
nonContractGroupSize	a logical number determining the number of work-group for non-contracting dimension
nonContractDim	determines the size of non contracting dimension for the flattened tensor
contractDim	determines the size of non contracting dimension for the flattened tensor
