Mojo struct
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 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)
from 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)

Methods
__del__
__del__(var 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.
