Event

class torch.mps.event.Event(enable_timing=False)

Wrapper around an MPS event.

MPS events are synchronization markers that can be used to monitor the device’s progress, to accurately measure timing, and to synchronize MPS streams.

Parameters

enable_timing (bool, optional) – indicates if the event should measure time (default: False)

elapsed_time(end_event)

Returns the time elapsed in milliseconds after the event was recorded and before the end_event was recorded.

Return type

float

query()

Returns True if all work currently captured by event has completed.

Return type

bool

record()

Records the event in the default stream.

synchronize()

Waits until the completion of all work currently captured in this event. This prevents the CPU thread from proceeding until the event completes.

wait()

Makes all future work submitted to the default stream wait for this event.
