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 | determins the total input data size |
