MemorySpace::MemorySpaceData< T, MemorySpace > Struct Template Reference

#include <deal.II/base/memory_space_data.h>

Detailed Description

template<typename T, typename MemorySpace>
struct MemorySpace::MemorySpaceData< T, MemorySpace >

Structure which stores data on the host or the device depending on the template parameter MemorySpace. Valid choices are MemorySpace::Host and MemorySpace::Default. The data is copied into the structure which then owns the data and will release the memory when the destructor is called.

Member Function Documentation

copy_to()

template<typename T, typename MemorySpace>

void MemorySpace::MemorySpaceData< T, MemorySpace >::copy_to	(	T *	begin,
		const std::size_t	n_elements )

Copy the class member values to begin. If the data is on the device it is moved to the host.

copy_from()

template<typename T, typename MemorySpace>

void MemorySpace::MemorySpaceData< T, MemorySpace >::copy_from	(	const T *	begin,
		const std::size_t	n_elements )

Copy the data in begin to the class member values. The pointer begin must be on the host.

Member Data Documentation

values_host_buffer

template<typename T, typename MemorySpace>

Kokkos::View<T *, Kokkos::HostSpace> MemorySpace::MemorySpaceData< T, MemorySpace >::values_host_buffer

Kokkos View owning a host buffer used for MPI communication.

Definition at line 68 of file memory_space_data.h.

values

template<typename T, typename MemorySpace>

Kokkos::View<T *, typename MemorySpace::kokkos_space> MemorySpace::MemorySpaceData< T, MemorySpace >::values

Kokkos View owning the data on the device (unless values_sm_ptr is used).

Definition at line 74 of file memory_space_data.h.

values_sm_ptr

template<typename T, typename MemorySpace>

std::shared_ptr<T> MemorySpace::MemorySpaceData< T, MemorySpace >::values_sm_ptr

Pointer to data on the host. The pointer points to the same data as values when using shared memory and the memory space is MemorySpace::Host. Otherwise it is not set.

Definition at line 86 of file memory_space_data.h.

values_sm

template<typename T, typename MemorySpace>

std::vector<ArrayView<const T> > MemorySpace::MemorySpaceData< T, MemorySpace >::values_sm

Pointers to the data of the processes sharing the same memory.
