aclprofGetStepTimestamp

Description

Sets the start timestamp and end timestamp of an iteration (or step), to display the profiling analysis result by step after training is implemented by using single-operator loading and execution APIs.

Prototype

aclError aclprofGetStepTimestamp(aclprofStepInfo* stepInfo, aclprofStepTag tag, aclrtStream stream)

Parameters

Parameter	Input/Output	Description
stepinfo	Input	Step information. Call aclprofCreateStepInfo to create data of the aclprofStepInfo type in advance.
tag	Input	Step start timestamp and end timestamp. Pass the enumerated value ACL_STEP_START at the step start and the enumerated value ACL_STEP_END at the step end.
stream	Input	Stream.

Returns

The value 0 indicates success, and other values indicate failure. For details, see aclError.
