Module Cuda.Delimited_event

This module builds on top of functionality more directly exposed by Event. It optimizes resource management for use-cases where events are not reused: there's only one call to Event.record, and it's immediately after Event.create.

type t

An delimited event encapsulates Event.t and is owned by a stream. It records its owner at creation, and gets released (using cuEventDestroy) when either it or its owner are synchronized (or if neither happens, when it is garbage-collected).

val sexp_of_t : t -> Sexplib0.Sexp.t
val record : ?blocking_sync:bool -> ?interprocess:bool -> ?external_:bool -> Stream.t -> t

Combines Event.create and Event.record to create an event owned by the given stream.

val is_released : t -> bool

Returns true if the delimited event is already released using cuEventDestroy. The event will be released by synchronize and Stream.synchronize.

val query : t -> bool

See Event.query. query event returns true when event is already released.

val synchronize : t -> unit

See Event.synchronize. synchronize event is a no-op if event is already released.

val wait : ?external_:bool -> Stream.t -> t -> unit

See Event.wait. wait stream event is a no-op if event is already released.
