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.

Member Function Documentation

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  q_point  ) const

inline

Return the quadrature point index of the given cell and q_point index. The index returned is only unique for a given MPI process.

Definition at line 460 of file portable_matrix_free.h.

get_quadrature_point()

template<int dim, typename Number = double>

Portable::MatrixFree< dim, Number >::point_type & Portable::MatrixFree< dim, Number >::Data::get_quadrature_point ( const unsigned int  cell, const unsigned int  q_point  ) const

inline

Return the quadrature point.

Definition at line 486 of file portable_matrix_free.h.

for_each_quad_point()

template<int dim, typename Number = double>

template<typename Functor >

void Portable::MatrixFree< dim, Number >::Data::for_each_quad_point ( const Functor &  func ) const

inline

Apply the given functor to each quadrature point in parallel.

func needs to define

DEAL_II_HOST_DEVICE void operator()(const int &q_point) const;
