<p>For an overview of distribute training, please refer to <a class="reference internal" href="README.html"><span class="doc">distributed training design doc</span></a>. In this design doc, we will discuss the parameter updater that will use parameter server cclient <a class="reference internal" href="pserver_client.html"><span class="doc">The Client Library of Parameter Server Design Doc</span></a> to manage and update parameters.</p>
<div class="section" id="parameter-updater">
<span id="parameter-updater"></span><h2>Parameter Updater<a class="headerlink" href="#parameter-updater" title="Permalink to this headline">¶</a></h2>
<p>Parameter Updater is used by trainer to manage and update parameter, there are mainly two kind of parameter updater: local and remote, since this design is for cluster train, we will only discuss remote parameter updater here.</p>
<div class="section" id="remote-parameter-updater">
<span id="remote-parameter-updater"></span><h3>Remote Parameter Updater<a class="headerlink" href="#remote-parameter-updater" title="Permalink to this headline">¶</a></h3>
<p>Remote Parameter Updater manage parameters through remote parameter server with the client that communicate with pserver(<a class="reference internal" href="pserver_client.html"><span class="doc">The Client Library of Parameter Server Design Doc</span></a>)</p>
<p>In PaddlePaddle Python V2 API, trainer is implemented in python, and the trainer will hold a instance of parameter updater and call it&#8217;s functions directly. In this design, we will also expose the api of RemoteParameterUpdater to python with swig.</p>

<p>Since we will only implement dense parameter management new, the mechanism for sparse parameter will be discussed in next stage.</p>
