Experiments with WRF on Intel® Many Integrated Core (Intel MIC) Architecture
Conference paper
Abstract
WRF is a well-known weather code with a hybrid OpenMP and MPI implementation. This paper investigates the performance of WRF on heterogeneous hardware consisting of Intel® Xeon® processors and Intel MIC Architecture co-processors, using offload, OpenMP, and MPI.
