class stream_and_event : public cuda::experimental::stf::event_impl

Public Functions

inline void insert_event()

inline void insert_dep(async_resources_handle &async_resources, const stream_and_event &from)

inline virtual bool factorize(backend_ctx_untyped&, reserved::event_vector &events) override

Remove implicit dependencies already induced by more recent events using the same stream.

inline virtual void sync_with_stream(backend_ctx_untyped &bctx, event_list &prereqs, cudaStream_t stream) const override

inline cudaStream_t get_stream() const

inline decorated_stream get_decorated_stream() const

inline ::std::ptrdiff_t get_stream_id() const

inline cudaEvent_t get_cuda_event() const

inline bool operator==(const event_impl &e) const

Compares this event with another event for equality based on their unique identifiers.

Parameters

e – The event to compare with.

Returns

True if the events have the same unique identifier, false otherwise.

inline bool operator<(const event_impl &e) const

Compares this event with another event for ordering based on their unique identifiers.

Parameters

e – The event to compare with.

Returns

True if this event’s unique identifier is less than the other event’s identifier, false otherwise.

template<typename context_t>
inline void set_symbol(context_t &ctx, ::std::string s)

Sets a symbolic name for the event, useful for debugging or tracing.

Parameters

s – The symbolic name to associate with this event.

inline virtual event_list from_stream(backend_ctx_untyped&, cudaStream_t) const

inline const ::std::string &get_symbol() const

Retrieves the symbolic name of the event.

Returns

The symbolic name of the event. Generates a default name if none was set.

Public Members

mutable reserved::unique_id_t unique_prereq_id

A unique identifier for the event, used to ensure proper event ordering.

::std::atomic<int> outbound_deps = 0
