Portable::DeviceBlockVector< Number > Class Template Reference

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

Detailed Description

template<typename Number>
class Portable::DeviceBlockVector< Number >

A block vector used for source and destination vectors in device functions like MatrixFree::cell_loop().

The maximum number of block is limited by the constant n_max_dof_handlers.
