Restrictions
- This API must be called before RunGraph. If it is called during model execution, the profile data after the aclgrphProfStart call is collected. As a result, the data may be incomplete.
- aclgrphProfStart must be called as a pair with, and before, aclgrphProfStop.
- aclgrphProfInit > aclgrphProfStart > aclgrphProfStop > aclgrphProfFinalize is a complete API call process. You have to follow the complete process if you want to switch models or graphs in a single process or perform multiple rounds of execution. Any API in this process cannot be called out of order or concurrently multiple times.
