Detailed Description

Various CUDA APIs need an object to store internal data. This structure creates, initializes, stores, and destroys these so-called handles for the respective CUDA libraries used inside deal.II.

Definition at line 44 of file cuda.h.

Constructor & Destructor Documentation

◆ Handle() [1/2]

Utilities::CUDA::Handle::Handle ( )

Constructor. Initialize the handles for the different libraries.

◆ Handle() [2/2]

Utilities::CUDA::Handle::Handle ( Handle const &  )

Copy constructor is deleted.

◆ ~Handle()

Utilities::CUDA::Handle::~Handle ( )

Destructor. Destroy the handles.

Member Data Documentation

◆ cusolver_dn_handle

cusolverDnHandle_t Utilities::CUDA::Handle::cusolver_dn_handle

Pointer to an opaque cuSolverDN context. The handle must be passed to every cuSolverDN library function.

Definition at line 65 of file cuda.h.

◆ cusolver_sp_handle

cusolverSpHandle_t Utilities::CUDA::Handle::cusolver_sp_handle

Pointer to an opaque cuSolverSP context. The handle must be passed to every cuSolverSP library function.

Definition at line 71 of file cuda.h.

◆ cusparse_handle

cusparseHandle_t Utilities::CUDA::Handle::cusparse_handle

Pointer to an opaque cuSPARSE context. The handle must be passed to every cuSPARSE library function.

Definition at line 77 of file cuda.h.
