| <h2>Server mode</h2> |
| </div> |
| |
| <div class="blog-post"> |
| |
| <p>The Joshua decoder can be run as a TCP/IP server instead of a POSIX-style command-line tool. Clients can concurrently connect to a socket and receive a set of newline-separated outputs for a set of newline-separated inputs.</p> |
| |
| <p>Threading takes place both within and across requests. Threads from the decoder pool are assigned in round-robin manner across requests, preventing starvation.</p> |
| |
| <h1 id="invoking-the-server">Invoking the server</h1> |
| |
| <p>A running server is configured at invokation time. To start in server mode, run <code class="highlighter-rouge">joshua-decoder</code> with the option <code class="highlighter-rouge">-server-port [PORT]</code>. Additionally, the server can be configured in the same ways as when using the command-line-functionality.</p> |
| |
| <p>E.g.,</p> |
| |
| <div class="highlighter-rouge"><pre class="highlight"><code>$JOSHUA/bin/joshua-decoder -server-port 10101 -mark-oovs false -output-format "%s" -threads 10 |
| </code></pre> |
| </div> |
| |
| <h2 id="using-the-server">Using the server</h2> |
| |
| <p>To test that the server is working, a set of inputs can be sent to the server from the command line. </p> |
| |
| <p>The server, as configured in the example above, will then respond to requests on port 10101. You can test it out with the <code class="highlighter-rouge">nc</code> utility:</p> |
| |
| <div class="highlighter-rouge"><pre class="highlight"><code>wget -qO - http://cs.jhu.edu/~post/files/pg1023.txt | head -132 | tail -11 | nc localhost 10101 |
| </code></pre> |
| </div> |
| |
| <p>Since no model was loaded, this will just return the text to you as sent to the server.</p> |
| |
| <p>The <code class="highlighter-rouge">-server-port</code> option can also be used when creating a <a href="bundle.html">bundled configuration</a> that will be run in server mode.</p> |
