DeviceEvent

struct DeviceEvent

Represents a GPU event for synchronization between streams.

A DeviceEvent allows for fine-grained synchronization between different GPU streams. Events can be recorded in one stream and waited for in another, enabling efficient coordination of asynchronous GPU operations.

Example:

from std.gpu.host import DeviceContext

var ctx = DeviceContext()

var default_stream = ctx.stream()
var new_stream = ctx.create_stream()

# Create event in default_stream
var event = ctx.create_event()

# Wait for the event in new_stream
new_stream.enqueue_wait_for(event)

# Stream 2 can continue
default_stream.record_event(event)

Implemented traits

AnyType, Copyable, ImplicitlyCopyable, ImplicitlyDestructible, Movable

Methods

__del__

__del__(deinit self)

Releases resources associated with this event.

synchronize

synchronize(self)

Blocks the calling CPU thread until this event completes.

This function waits until the event has been recorded and all operations before the event in the stream have completed.

Raises:

If synchronization fails.
