| <span id="math-library-selection"></span><h3>Math Library Selection<a class="headerlink" href="#math-library-selection" title="Permalink to this headline">¶</a></h3> |
| <p>It is useful to consider your math library selection prior to your other prerequisites. |
| MXNet relies on the |
| <a class="reference external" href="https://en.wikipedia.org/wiki/Basic_Linear_Algebra_Subprograms">BLAS</a> (Basic |
| Linear Algebra Subprograms) library for numerical computations. |
| Those can be extended with <a class="reference external" href="https://github.com/Reference-LAPACK/lapack">LAPACK (Linear Algebra Package)</a>, an additional set of mathematical functions.</p> |
| <p>MXNet supports multiple mathematical backends for computations on the CPU:</p> |
| <ul class="simple"> |
| <li><a class="reference external" href="https://developer.apple.com/documentation/accelerate">Apple Accelerate</a></li> |
| <li><a class="reference external" href="http://math-atlas.sourceforge.net/">ATLAS</a></li> |
| <li><a class="reference external" href="https://software.intel.com/en-us/intel-mkl">MKL</a> (MKL, MKLML)</li> |
| <li><a class="reference external" href="https://github.com/intel/mkl-dnn">MKL-DNN</a></li> |
| <li><a class="reference external" href="http://www.openblas.net/">OpenBLAS</a></li> |
| </ul> |
| <p>The default order of choice for the libraries if found follows the path from the most |
| (recommended) to less performant backends. |
| The following lists show this order by library and <code class="docutils literal"><span class="pre">cmake</span></code> switch.</p> |
| <p>For desktop platforms (x86_64):</p> |
| <ol class="simple"> |
| <li>MKL-DNN (submodule) | <code class="docutils literal"><span class="pre">USE_MKLDNN</span></code></li> |
| <li>MKL | <code class="docutils literal"><span class="pre">USE_MKL_IF_AVAILABLE</span></code></li> |
| <li>MKLML (downloaded) | <code class="docutils literal"><span class="pre">USE_MKLML</span></code></li> |
| <li>Apple Accelerate | <code class="docutils literal"><span class="pre">USE_APPLE_ACCELERATE_IF_AVAILABLE</span></code> | Mac only</li> |
| <li>OpenBLAS | <code class="docutils literal"><span class="pre">BLAS</span></code> | Options: Atlas, Open, MKL, Apple</li> |
| </ol> |
| <p>Note: If <code class="docutils literal"><span class="pre">USE_MKL_IF_AVAILABLE</span></code> is set to False then MKLML and MKL-DNN will be disabled as well for configuration |
| backwards compatibility.</p> |
| <p>For embedded platforms (all other and if cross compiled):</p> |
| <ol class="simple"> |
| <li>OpenBLAS | <code class="docutils literal"><span class="pre">BLAS</span></code> | Options: Atlas, Open, MKL, Apple</li> |
| </ol> |
| <p>You can set the BLAS library explicitly by setting the BLAS variable to:</p> |
| <ul class="simple"> |
| <li>Atlas</li> |
| <li>Open</li> |
| <li>MKL</li> |
| <li>Apple</li> |
| </ul> |
| <p>See the <a class="reference external" href="https://github.com/apache/incubator-mxnet/blob/master/cmake/ChooseBlas.cmake">cmake/ChooseBLAS.cmake</a> file for the options.</p> |
| <p>Intel’s MKL (Math Kernel Library) is one of the most powerful math libraries |
| https://software.intel.com/en-us/mkl</p> |
| <p>It has following flavors:</p> |
| <ul class="simple"> |
| <li>MKL is a complete math library, containing all the functionality found in ATLAS, OpenBlas and LAPACK. It is free under |
| community support licensing (https://software.intel.com/en-us/articles/free-mkl), |
| but needs to be downloaded and installed manually.</li> |
| <li>MKLML is a subset of MKL. It contains a smaller number of functions to reduce the |
| size of the download and reduce the number of dynamic libraries user needs.</li> |
| </ul> |
| <!-- [Removed until #11148 is merged.] This is the most effective option since it can be downloaded and installed automatically |
| by the cmake script (see cmake/DownloadMKLML.cmake).--><ul class="simple"> |
| <li>MKL-DNN is a separate open-source library, it can be used separately from MKL or MKLML. It is |
| shipped as a subrepo with MXNet source code (see 3rdparty/mkldnn or the <a class="reference external" href="https://github.com/intel/mkl-dnn">MKL-DNN project</a>)</li> |
| </ul> |
| <p>Since the full MKL library is almost always faster than any other BLAS library it’s turned on by default, |
| however it needs to be downloaded and installed manually before doing <code class="docutils literal"><span class="pre">cmake</span></code> configuration. |
| Register and download on the <a class="reference external" href="https://software.intel.com/en-us/performance-libraries">Intel performance libraries website</a>.</p> |
| <p>Note: MKL is supported only for desktop builds and the framework itself supports the following |
| hardware:</p> |
| <ul class="simple"> |
| <li>Intel® Xeon Phi™ processor</li> |
| <li>Intel® Xeon® processor</li> |
| <li>Intel® Core™ processor family</li> |
| <li>Intel Atom® processor</li> |
| </ul> |
| <p>If you have a different processor you can still try to use MKL, but performance results are |
| unpredictable.</p> |

| Apache MXNet is an effort undergoing incubation at The Apache Software Foundation (ASF), <strong>sponsored by the <i>Apache Incubator</i></strong>. Incubation is required of all newly accepted projects until a further review indicates that the infrastructure, communications, and decision making process have stabilized in a manner consistent with other successful ASF projects. While incubation status is not necessarily a reflection of the completeness or stability of the code, it does indicate that the project has yet to be fully endorsed by the ASF. |
