Usage of "cl_cache" for multiple instance/thread

Hi team,

I'm using "cl_cache" method to reduce model loading time for GPU backend case, and wonder whether we can get benefit of using "cl_cache" for following case, too.

Case #1: Single thread operation and creating multiple instances: Can 2nd/3rd/.. instances use cl_cache created by 1st instances to reduce model loading time?

Case #2: Multiple thread operation: Can 2nd/3rd./.. thread use cl_cache created by 1st thread?

Thank you.
