| <h1>Step 6: Use GPUs to increase efficiency<a class="headerlink" href="#Step-6:-Use-GPUs-to-increase-efficiency" title="Permalink to this headline">¶</a></h1> |
| <p>In this step, you learn how to use graphics processing units (GPUs) with MXNet. If you use GPUs to train and deploy neural networks, you get significantly more computational power when compared to central processing units (CPUs).</p> |
| <div class="section" id="Prerequisites"> |
| <h2>Prerequisites<a class="headerlink" href="#Prerequisites" title="Permalink to this headline">¶</a></h2> |
| <p>Before you start the other steps here, make sure you have at least one Nvidia GPU in your machine and CUDA properly installed. GPUs from AMD and Intel are not supported. Install the GPU-enabled version of MXNet.</p> |
| <p>Use the following commands to check the number GPUs that are available.</p> |

| <p>MXNet’s ndarray is very similar to NumPy. One major difference is MXNet’s ndarray has a <code class="docutils literal notranslate"><span class="pre">context</span></code> attribute that specifies which device an array is on. By default, it is on <code class="docutils literal notranslate"><span class="pre">npx.cpu()</span></code>. Change it to the first GPU with the following code. Use <code class="docutils literal notranslate"><span class="pre">npx.gpu()</span></code> or <code class="docutils literal notranslate"><span class="pre">npx.gpu(0)</span></code> to indicate the first GPU.</p> |

| <p>If you’re using a CPU, MXNet allocates data on main memory and tries to use as many CPU cores as possible. This is true even if there is more than one CPU socket. If there are multiple GPUs, MXNet specifies which GPUs the ndarray is allocated.</p> |
| <p>Assume there is a least one more GPU. Create another ndarray and assign it there. If you only have one GPU, then you get an error. In the example code here, you copy <code class="docutils literal notranslate"><span class="pre">x</span></code> to the second GPU, <code class="docutils literal notranslate"><span class="pre">npx.gpu(1)</span></code>:</p> |

| <p>To perform an operation on a particular GPU, you only need to guarantee that the input of an operation is already on that GPU. The output is allocated on the same GPU as well. Almost all operators in the <code class="docutils literal notranslate"><span class="pre">np</span></code> and <code class="docutils literal notranslate"><span class="pre">npx</span></code> module support running on a GPU.</p> |
