It provides access to simulation data using an intuitive python<br>interface, can quickly and easily perform many common visualization and analysis<br>tasks, and offers a framework for conducting data reductions and analysis of<br>simulation data. More details about yt, including download and installation<br>instructions as well as full documentation are available on our website:<br><a href="http://yt-project.org/">http://yt-project.org</a>.<br><br>Up to this point, yt development has proceeded largely over the internet,<br>leveraging e-mail lists, our online code repository<br>(<a href="http://bitbucket.org/yt_analysis">http://bitbucket.org/yt_analysis</a>), and IRC to track, discuss, and evaluate<br>changes to the code. Unfortunately, this model makes it difficult to jump in to<br>development as a newcomer. This workshop will not only allow experienced<br>developers to collaborate in person on new features, but will also be a means<br>for new developers to learn what yt is about and begin contributing. The<br>workshop will include several training sessions, constituting a primer in<br>distributed version control, test-based development, and best practices for<br>scientific programming.<br><br>The workshop will also serve as a venue to plan and execute some of the major<br>new features we are planning for the upcoming yt 3.0 release, including full<br>support for outputs of Lagrangian codes like Gadget, Gasoline and AREPO, better <br>support for oct-based codes like ART and RAMSES, initial conditions generation, <br>the new Grid Data Format, a new way of handling units and unit conversion, <br>non-cartesian geometries, and advanced graphical browser widgets inside the <br>iPython notebook.<br><br>More information and a registration form for the workshop are available on the<br>workshop website: <a href="http://yt-project.org/workshop2013/">http://yt-project.org/workshop2013/</a>. We have limited funding<br>support for hotels and airfare. Funds will be preferentially distributed to<br>students and the level of individual support will depend on demand.<br><br>If you have questions or concerns about the workshop, please feel free to<br>contact the organizers at <a href="mailto:workshop2013@yt-project.org">workshop2013@yt-project.org</a>.<br><br>Regards,<div><br></div><div>The Organizing Committee</div></body></html>
