In the High Performance Computing (HPC) area, parallel computing techniques such as MPI, OpenMP*, one-sided communications, shmem, and Fortran coarray are widely utilized. This blog is part of a series that will introduce the use of these techniques, especially how to use them on the Intel® Xeon Phi™ coprocessor. This first blog discusses the main usage of the hybrid MPI/OpenMP model.
I don’t know if any of you have noticed but Intel® has a tendency to emphasize its own homegrown tools. This isn’t bad as Intel has some of the best. Still, if someone has a favorite hammer, there’s a tendency to use that hammer for just about everything.
How about the future? Have we reached the pinnacle of power management?
This document demonstrates the best methods to obtain, build and run the WRF model on multiple nodes in symmetric mode on Intel® Xeon Phi™ Coprocessors and Intel® Xeon processors. This document also describes the WRF software configuration and affinity settings to extract the best performance from multiple node symmetric mode operation when using Intel Xeon Phi Coprocessor and an Intel Xeon processor.
