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

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

Detailed Description

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

A pointer to this data structure is passed to the user code in device code that computes operations in quadrature points. It can be used to construct Portable::FEEvaluation objects and contains necessary precomputed data and scratch memory space to perform matrix-free evaluations.

local_q_point_id()

template<int dim, typename Number = double>

unsigned int Portable::MatrixFree< dim, Number >::Data::local_q_point_id ( const unsigned int cell, const unsigned int n_q_points, const unsigned int q_point ) const

inline

Return the quadrature point index local. The index is only unique for a given MPI process.
