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.
MKL has many customers who have been successfully using MKL on servers and clusters for many years. Recently, there are also quite a few customers who have successfully used MKL on Intel Xeon Phi enabled clusters. But it is critical for us to learn different user experience and stories. I will send you a message to your registered email address to discuss.
