Context management

newtype Handle

An opaque handle to the cuSPARSE library context, which is passed to all library function calls.

Constructors

Handle

Fields

• useHandle :: Ptr ()

create :: IO Handle

This function initializes the cuSPARSE library and creates a handle on the cuSPARSE context. It must be called before any other cuSPARSE API function is invoked. It allocates hardware resources necessary for accessing the GPU.

http://docs.nvidia.com/cuda/cusparse/index.html#cusparsecreate

destroy :: Handle -> IO ()

This function releases CPU-side resources used by the cuSPARSE library. The release of GPU-side resources may be deferred until the application shuts down.

Utilities

data PointerMode

For functions which take scalar value arguments, determines whether those values are passed by reference on the host or device.

Instances

Enum PointerMode

Defined in Foreign.CUDA.BLAS.Sparse.Context

Methods

succ :: PointerMode -> PointerMode

pred :: PointerMode -> PointerMode

toEnum :: Int -> PointerMode

fromEnum :: PointerMode -> Int

enumFrom :: PointerMode -> [PointerMode]

enumFromThen :: PointerMode -> PointerMode -> [PointerMode]

enumFromTo :: PointerMode -> PointerMode -> [PointerMode]

enumFromThenTo :: PointerMode -> PointerMode -> PointerMode -> [PointerMode]

Eq PointerMode

Defined in Foreign.CUDA.BLAS.Sparse.Context

Methods

(==) :: PointerMode -> PointerMode -> Bool

(/=) :: PointerMode -> PointerMode -> Bool

Show PointerMode

Defined in Foreign.CUDA.BLAS.Sparse.Context

Methods

showsPrec :: Int -> PointerMode -> ShowS

show :: PointerMode -> String

showList :: [PointerMode] -> ShowS

setPointerMode :: Handle -> PointerMode -> IO ()

Set the pointer mode used by cuSPARSE library functions.

The default mode is for values to be passed by reference from the host.

getPointerMode :: Handle -> IO PointerMode

Get the pointer mode used by cuSPARSE library functions to pass scalar arguments.
