title: CI Servers for system simulation
body: <p>My group work for a software of simulation for plane. To achieve a faster and easier validation and verification, we decided to introduce continuous integration. But I have no idea which CI servers should we choose.</p>
  
  <p>Our contraintes:</p>
  
  <pre><code>   - We need to compile in different machine with different platform( Linux, HP ) in local net and in client's net.
       I mean, we need to call different functions in different machine in distance. Some of them will need a authorise
     - We prefer a CI servers open source
     - The sources are in different languages, C, C++, Java ...
     - Support SVN, CVS, Clearcase
     - Automated tests and reports
     - The tests need different machines working together
  </code></pre>
  
  <p>I've seen teamcity, it seems well, but it's not open source.</p>
