<div class="textblock"><p>SimGrid comes with many examples provided in the examples/ directory. Those examples are described in section <a class="el" href="group__msg__examples.html">MSG examples</a>. Those examples are commented and should be easy to understand. for a first step into SimGrid we also provide some more detailed examples in the sections below.</p>
<p>
You should also check our online <a href="http://simgrid.gforge.inria.fr/documentation.html"> tutorial section</a> that contains a generic tutorial about using SimGrid.

Using MSG</h1>
<p>
You should also check our online <a href="http://simgrid.gforge.inria.fr/documentation.html"> tutorial section</a> that contains a dedicated tutorial.
</p>
<p>Here are some examples on how to use MSG, the most used API.</p>
<p>MSG comes with an extensive set of examples. It is sometimes difficult to find the one you need. This list aims at helping you finding the example from which you can learn what you want to.</p>
<h2><a class="anchor" id="MSG_ex_basics"></a>
Basic examples and features</h2>
<h3><a class="anchor" id="MSG_ex_master_worker"></a>
Basic Master/Workers</h3>
<p>Simulation of a master-worker application using a realistic platform and an external description of the deployment.</p>

<p>A host can send an asynchronous message with <code><a class="el" href="group__msg__task__usage.html#gaa280111a523d70bb36061e6e52ca1b42" title="Sends a task on a mailbox.

">MSG_comm_destroy()</a></code>. It is also possible to call <code><a class="el" href="group__msg__task__usage.html#ga2ae956f1e7a1014652d85b5f8db42aa3" title="Wait for the completion of a communication.
