MultiLevel Parallelism with Intel Xeon Phi

"The combination of using both MPI and OpenMP is a topic that has been explored by many developers in order to determine the most optimum solution. Whether to use OpenMP for outer loops and MPI within, or by creating separate MPI processes and using OpenMP within can lead to various levels of performance. In most cases of determining which method will yield the best results will involve a deep understanding of the application, and not just rearranging directives."
