Function

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 model 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. For details about the type definition, see aclprofStepInfo, aclprofStepTag, and aclrtStream.
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.

Parameter

Description

stepInfo

Input

Step information. Call aclprofCreateStepInfo to create data of the aclprofStepInfo type in advance.

For details about the type definition, see aclprofStepInfo, aclprofStepTag, and aclrtStream.

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

0 on success; else, failure. For details, see aclError.
