Parallelization Using Intel® MPI

Compiler Methodology for Intel® MIC Architecture

Parallelization Using Intel® MPI

This chapter covers Intel® MPI.


The Intel Compilers are compatible with the Intel® MPI library for Intel Architecture including the Intel® Xeon® Phi™ coprocessors. 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.

This article is part of the Intel® Modern Code Developer Community documentation which supports developers in leveraging application performance in code through a systematic step-by-step optimization framework methodology. This article addresses: multi-node parallelization.


Using Intel® MPI with the Intel Compilers

Take Aways

The Intel Compilers are compatible with Intel® MPI.  Information on using MPI applications with the Intel compiler is covered outside of this compiler documentation. 


It is essential that you read this guide from start to finish using the built-in hyperlinks to guide you along a path to a successful port and tuning of your application(s) on Intel® Xeon® Phi™ architecture.  The paths provided in this guide reflect the steps necessary to get best application performance on Xeon Phi architecture.
