Instructors will be Irène Buvat, Albertine Dubois, Sebastien Jan and Simon Stute.<br /><br /> Two days will be devoted to using and running GATE (setting up and launching simulations, source description, analytical phantoms, voxelized phantoms, data output, digitizer and dead time modeling, modeling radiotherapy experiments) and the remaining day will be dedicated to building a simulation with Geant4 and to C++ developments in GATE. Training includes a lot of hands-on to get familiar with using GATE.<br /><br /> Registration fees are 930 € for three days including lunch and coffee breaks, part of the transportation and training material. The maximum number of attendees is almost reached, so if you are interested in attending this training session, please quickly visit this <a href="http://www.opengatecollaboration.org/GATEtraining2013" class="type1"><b>page</b></a> for all practical details, registration form and detailed program.</div> </p><p></p></span> </td> <td width="65% align="left" valign="top" bgcolor="#feecd2" class="brder2"> <span class="text3">SPECIAL FOCUS ON GATELAB</span><br /> <span class="text4"><br /> <p class="text4"> <div align="justify">GateLab is a web browser application to easily launch Gate simulations on a large computing infrastructure. GATE simulations are executed with tens or hundreds of computers in parallel on the European Grid Infrastructure (<a href="http://www.egi.eu" class="type1"><b>EGI</b></a>). </div></p> <p>GateLab's main features are:<br /> <strong class="text4">•</strong> <class="text4">One click submission from a web browser: upload your main macro file, the system will detect and upload all additional files necessary for your simulations.<br /> <strong class="text4">•</strong> <class="text4">Simulation monitoring.<br /> <strong class="text4">•</strong> <class="text4">Automatic results merging: once the simulation is completed, results are ready for download on your workstation. <br /></class="text4"></class="text4"></class="text4"></p> <div align="justify">GateLab system started in 2008. After a test version released in 2011, a beta version of GateLab has been made available to the users since February 2012. Since then, 187 users registered, launching about 200 simulations per month. The global average speedup of simulations is around 50 (taking queing and merging into account) but it is not rare to reach speedup greater than 200. The record is about 350 times faster. <p>Because the GateLab system is quite new, there are still some limitations. For instance, the fastest mode (dynamic mode) can only be used for radiation therapy applications. Static mode has to be used for PET/SPECT simulations. The main limitation concerns PET simulations having multiple runs that cannot yet be launched with GateLab. GateLab's team is working on it. </p> <p>How to start and find more detailed information ?<br /> Go to the following <a href="http://vip.creatis.insa-lyon.fr" class="type1"><b>page</b></a> and ask for an account.
