WRF Conus2.5km on Intel® Xeon Phi™ Coprocessors and Intel® Xeon® processors in Symmetric Mode

Overview

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.

  • Introduction to Embree 2.1 - Part 1

    This is part of a series of blogs on Embree, a collection of high performance ray tracing kernels. Embree has been released open source since version 1.0. Version 2.0 was released during SIGGRAPH 2013 and Embree 2.1 was published on github just before Christmas 2013. The official web site has an overview on Embree with links to source code and example data sets. I'm not going to duplicate what's already been said over there and in the README.txt.

    Understanding Gather-Scatter instructions and the -gather-scatter-unroll compiler switch

    Gather-Scatter instructions may not be the optimal choice of instructions when you are trying to achieve superior performance on the Intel® Xeon Phi™ coprocessor.  However, if your code uses indirect addressing or performs non-unit strided memory accesses, gather-scatter instructions may be the best option.

    Autotools and Intel® Xeon Phi™ Coprocessor [PDF 462KB]

    One of the strengths of the Intel® Xeon Phi™ coprocessor is the ability to build existing software to run on the Intel® Many Integrated Core (Intel® MIC) hardware with a minimum of change (in most cases, no changes to the code itself are necessary). The same cannot always be said, however, for the build systems used to compile existing software packages.
