Member Functions

¶std::optional<std::chrono::nanoseconds>
get_native_execution_time()

Description

Returns the time execution time as measured if profiling was enabled in the issuing component. Requires is_complete() to be true.

Declared at: include/backend/sycl_backend.h:19

---

¶bool is_complete()

Description

If this function returns true once, the implementation must guarantee that it will always do so in the future. The event is expected to be cheap to poll repeatedly, and the operation must proceed in the background even while not being polled.
