Best Known Method
Running an MPI program in symmetric mode on an Intel® Xeon® host and an Intel Xeon Phi™ coprocessor may deadlock in specific cases due to the heterogeneous precision in replicated control flow calculations. The advice is to determine the control flow only on one master MPI process.
Intel MPI applications can be executed on multiple combinations of Intel Xeon processors and Intel Xeon Phi coprocessors. Four different execution models are supported:
