Constructor & Destructor Documentation

◆ MPISharedMemDeleterAction()

template<class T >
AlignedVector< T >::Deleter::MPISharedMemDeleterAction::MPISharedMemDeleterAction ( const bool  is_shmem_root,
T *  aligned_shmem_pointer,
MPI_Comm  shmem_group_communicator,
MPI_Win  shmem_window 
)

Constructor. Store the various pieces of information necessary to identify the MPI window in which the data resides.

Member Function Documentation

◆ delete_array()

template<class T >
virtual void AlignedVector< T >::Deleter::MPISharedMemDeleterAction::delete_array ( const AlignedVector< T > *  aligned_vector,
T *  ptr 
)
virtual

The function that implements the action of de-allocating memory. It receives as arguments a pointer to the owning AlignedVector object as well as a pointer to the memory being de-allocated.

Implements AlignedVector< T >::Deleter::DeleterActionBase.
