Detailed Description

template<typename T>
class uni20::cuda::BlockingWriteAccess< T >

Scoped read/write CUDA pointer access after a host-side synchronization.

Construction waits for all prior reader and writer completions. Release publishes no CUDA event because the guarded operation must have completed synchronously on the host.

Member Function Documentation

data()

template<typename T >

T * uni20::cuda::BlockingWriteAccess< T >::data ( ) const

inlinenoexcept

Return the typed device pointer for a blocking runtime operation.

operator=() [1/2]

template<typename T >

BlockingWriteAccess & uni20::cuda::BlockingWriteAccess< T >::operator= ( BlockingWriteAccess< T > &&  other )

inlinenoexcept

operator=() [2/2]

template<typename T >

BlockingWriteAccess & uni20::cuda::BlockingWriteAccess< T >::operator= ( BlockingWriteAccess< T > const &  )

delete

release()

template<typename T >

void uni20::cuda::BlockingWriteAccess< T >::release ( )

inlinenoexcept

End the scoped host-synchronized write access.

release_with_completion()

template<typename T >

void uni20::cuda::BlockingWriteAccess< T >::release_with_completion ( Completion  completion )

inlinenoexcept

Publish externally submitted device completion and end the scoped access.

Use this when a blocking host operation has finished consuming its host operands but leaves ordered device work outstanding.

size()

template<typename T >

std::size_t uni20::cuda::BlockingWriteAccess< T >::size ( ) const

inlinenoexcept

Return the number of typed elements in the allocation.

storage() [1/2]

template<typename T >

CudaBuffer< T > & uni20::cuda::BlockingWriteAccess< T >::storage ( )

inline

Return the mutable CUDA buffer retained by this access object.

storage() [2/2]

template<typename T >

CudaBuffer< T > const & uni20::cuda::BlockingWriteAccess< T >::storage ( ) const

inline

Return the read-only CUDA buffer retained by this access object.
