Compiling Open Source for Intel® Xeon Phi™ Coprocessors

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) architecture 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.

For software built with nothing more complicated than Makefiles (or even just invoking the Intel® Composer XE compiler directly), the necessary build change is often as simple as adding –mmic to the set of compiler and link flags.[1] When the build scripts are generated via GNU Autotools (automake/autoconf), SCons or Kitware CMake, however, the process is different..

Below are links to three articles that cover the mechanics of how to build existing Open Source packages:


It should also be noted that several libraries and packages are compiled and provided with the "Software for Coprocessor OS" that comes with newer Intel(R) MPSS distributions


[1] The process is  slightly more complicated for code builds that  involve “fat” libraries and binaries – those including code intended to run on both Intel® Xeon® and Intel® Xeon Phi™ coprocessor hardware. Such scenarios are outside the scope of these articles.
