Detailed Description

template<typename Scalar, typename StorageIndex, StorageIndex REG_SIZE_M, StorageIndex REG_SIZE_N, StorageIndex TSDK>
struct Eigen::TensorSycl::internal::TTPanelSize< Scalar, StorageIndex, REG_SIZE_M, REG_SIZE_N, TSDK >

TTPanelSize, a template class used for setting the panel size required for launching General Tensor Tensor contraction kernel on various hardware devices.

Template Parameters

Scalar	determines the element type of the tensor
StorageIndex	determines the Index type.
REG_SIZE_M	determines workload per thread for loading the M dimension This can be varied based on the available register on a chosen device(can be controlled by EIGEN_SYCL_REG_M macro).
REG_SIZE_N	determines workload per thread for loading the N dimension This can be varied based on the available register on a chosen device(can be controlled by EIGEN_SYCL_REG_N macro).
TSDK	determines Tile size for dimension K. The packet size is assumed to be considered
