I'm evaluating MKL for internal use on both servers and potentially a Phi cluster. I've encountered a number of frustrating bugs, poor documentation, and performance problems. Does Intel ever make MKL source code available under an NDA? If so, please contact me regarding pricing and other details. Access to the source code would make it easier to debug and optimize MKL application and to understand MKL's performance characteristics.
