For KNL you want to be using the OpenMP backend. The key here is to make sure that you get the number of OpenMP threads correct, have MKL available, use the ICC compiler, and have libxsmm installed. Together, these should result in rather good performance for non-pathological test cases. The MIC backend is for the legacy Knights Corner.
