Classes
class	viennacl::backend::cuda::cuda_exception
struct	viennacl::backend::cuda::detail::cuda_deleter< U >
	Functor for deleting a CUDA handle. Used within the smart pointer class. More...

Namespaces
	viennacl
	Main namespace in ViennaCL. Holds all the basic types such as vector, matrix, etc. and defines operations upon them.
	viennacl::backend
	Namespace providing routines for handling the different memory domains.
	viennacl::backend::cuda
	Provides implementations for handling CUDA memory buffers.
	viennacl::backend::cuda::detail
	Holds implementation details for handling CUDA memory buffers. Not intended for direct use by library users.

Macros
#define	VIENNACL_CUDA_ERROR_CHECK(err)   detail::cuda_error_check (err, __FILE__, __LINE__)

Typedefs
typedef viennacl::tools::shared_ptr < char >	viennacl::backend::cuda::handle_type

Functions
void	viennacl::backend::cuda::detail::cuda_error_check (cudaError error_code, const char *file, const int line)
handle_type	viennacl::backend::cuda::memory_create (vcl_size_t size_in_bytes, const void *host_ptr=NULL)
	Creates an array of the specified size on the CUDA device. If the second argument is provided, the buffer is initialized with data from that pointer. More...
void	viennacl::backend::cuda::memory_copy (handle_type const &src_buffer, handle_type &dst_buffer, vcl_size_t src_offset, vcl_size_t dst_offset, vcl_size_t bytes_to_copy)
	Copies 'bytes_to_copy' bytes from address 'src_buffer + src_offset' on the CUDA device to memory starting at address 'dst_buffer + dst_offset' on the same CUDA device. More...
void	viennacl::backend::cuda::memory_write (handle_type &dst_buffer, vcl_size_t dst_offset, vcl_size_t bytes_to_copy, const void *ptr, bool async=false)
	Writes data from main RAM identified by 'ptr' to the CUDA buffer identified by 'dst_buffer'. More...
void	viennacl::backend::cuda::memory_read (handle_type const &src_buffer, vcl_size_t src_offset, vcl_size_t bytes_to_copy, void *ptr, bool async=false)
	Reads data from a CUDA buffer back to main RAM. More...
