Stream

An execution stream: an ordered queue of device work. Operations submitted to it run in order, asynchronously of the host. A created stream pipelines submission and overlaps independent work; the per-device default stream dispatches on the calling thread instead.

device (property)​

The device this stream runs on.

__init__​

__init__(self, /, *args, **kwargs)

Initialize self. See help(type(self)) for accurate signature.

create​

create(*args, **kwargs)

create(device: clika_runtime._core.Device) -> clika_runtime._core.Stream

Allocate a fresh non-default stream on device (for overlapping work).

default_stream​

default_stream(*args, **kwargs)

default_stream(device: clika_runtime._core.Device) -> clika_runtime._core.Stream

The per-device default stream; always valid.

is_default​

is_defaultis_default(self) -> bool

is_default(self) -> bool

True if this is the device's default stream.

query_idle​

query_idlequery_idle(self) -> bool

query_idle(self) -> bool

True if the stream currently has no work in flight (a hint, not a barrier).

synchronize​

synchronizesynchronize(self) -> None

synchronize(self) -> None

Block until all work submitted on this stream has completed.
