std::shared_ptr< T > | values_sm_ptr |
std::vector< ArrayView< const T > > | values_sm |
Structure which stores data on the host or the device depending on the template parameter MemorySpace
. Valid choices are MemorySpace::Host, MemorySpace::Default, and MemorySpace::CUDA (if CUDA was enabled in deal.II). The data is copied into the structure which then owns the data and will release the memory when the destructor is called.

MemorySpace::MemorySpaceData< T, MemorySpace >::MemorySpaceData | ( | ) |
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.
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.
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 67 of file memory_space_data.h.
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 75 of file memory_space_data.h.
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 87 of file memory_space_data.h.
std::vector<ArrayView<const T> > MemorySpace::MemorySpaceData< T, MemorySpace >::values_sm |
Pointers to the data of the processes sharing the same memory.
