Portable::MatrixFree< dim, Number >::PrecomputedData Struct Reference

#include <deal.II/matrix_free/portable_matrix_free.h>

Detailed Description

template<int dim, typename Number = double>
struct Portable::MatrixFree< dim, Number >::PrecomputedData

Structure which is passed to the kernel for a single DoFHandler. It is used to pass all the necessary information from the CPU to the GPU and is precomputed on the CPU. This data is read-only once we run on the GPU.
