Compiler Methodology for Intel® MIC Architecture

This chapter covers the Intel® Composer XE for Linux suite support for Intel® MPI.

Overview

The Intel® Composer XE 2013 for Linux suite is compatible with the Intel® MPI library for Intel Architecture including the Intel® Xeon® Phi™ coprocessor . The Message Passing Interface (MPI) is one of many options available for you to parallelize your application (if it is not already using MPI.  MPI is a popular form of distributed memory parallelism such as clusters.  We do not cover details on MPI use on Intel® Xeon® Phi™ coprocessors in this document.  This information is covered in separate documents.  We simply provide references here to external documentation.

Using Intel® MPI with the Intel Compilers

Support for Intel® MPI is evolving in 2012 and 2013. The latest information on MPI support is available in the articles: Using the Intel® MPI Library on Intel® Xeon Phi™ Coprocessor Systems and Intel® Cluster Tools and the Intel® Xeon Phi™ Coprocessors.

Take Aways

The Intel® Composer XE 2013 for Linux suite is compatible with Intel® MPI.  Information on using MPI applications with the Intel compiler is covered outside of this compiler documentation.
