Detailed Description

Strongly-typed non-owning wrapper for CUDA streams with default constructor.

This wrapper is simply a "view": it does not own the lifetime of the stream it wraps.

Constructor & Destructor Documentation

cuda_stream_view() [1/2]

constexpr rmm::cuda_stream_view::cuda_stream_view ( cudaStream_t  stream )

inlineconstexprnoexcept

Constructor from a cudaStream_t.

Parameters

stream

The underlying stream for this view

cuda_stream_view() [2/2]

constexpr rmm::cuda_stream_view::cuda_stream_view ( cuda::stream_ref  stream )

inlineconstexprnoexcept

Implicit conversion from stream_ref.

Parameters

stream

The underlying stream for this view

Member Function Documentation

is_default()

bool rmm::cuda_stream_view::is_default ( ) const

inlinenoexcept

true if the wrapped stream is explicitly the CUDA legacy default stream

Returns

true if the wrapped stream is explicitly the CUDA legacy default stream

is_per_thread_default()

bool rmm::cuda_stream_view::is_per_thread_default ( ) const

inlinenoexcept

true if the wrapped stream is the CUDA per-thread default stream

Returns

true if the wrapped stream is the CUDA per-thread default stream

operator cuda::stream_ref()

constexpr rmm::cuda_stream_view::operator cuda::stream_ref ( ) const

inlineconstexprnoexcept

Implicit conversion to stream_ref.

Returns

stream_ref The underlying stream referenced by this cuda_stream_view

operator cudaStream_t()

constexpr rmm::cuda_stream_view::operator cudaStream_t ( ) const

inlineconstexprnoexcept

Implicit conversion to cudaStream_t.

Returns

cudaStream_t The underlying stream referenced by this cuda_stream_view

operator=() [1/2]

constexpr cuda_stream_view& rmm::cuda_stream_view::operator= ( cuda_stream_view &&  )

constexprdefault

Default move assignment operator.

Returns

cuda_stream_view& Reference to the assigned object

operator=() [2/2]

constexpr cuda_stream_view& rmm::cuda_stream_view::operator= ( cuda_stream_view const &  )

constexprdefault

Default copy assignment operator.

Returns

cuda_stream_view& Reference to the assigned object

synchronize()

void rmm::cuda_stream_view::synchronize ( ) const

inline

Synchronize the viewed CUDA stream.

Calls cudaStreamSynchronize().

Exceptions

rmm::cuda_error

if stream synchronization fails

synchronize_no_throw()

void rmm::cuda_stream_view::synchronize_no_throw ( ) const

inlinenoexcept

Synchronize the viewed CUDA stream. Does not throw if there is an error.

Calls cudaStreamSynchronize() and asserts if there is an error.

value()

constexpr cudaStream_t rmm::cuda_stream_view::value ( ) const

inlineconstexprnoexcept

Get the wrapped stream.

Returns

cudaStream_t The underlying stream referenced by this cuda_stream_view
