Abstract

Highlights: A multi-threaded version of Geant4 was developed for use on multi-core computers. The Geant4 geometry modeler was optimized for speed and complex volumes. Electromagnetic, hadronic and decay physics were improved. A versatile, multi-driver visualization system was developed. Geant4 has adopted the CMake build system. Abstract: During the last two to three years extensive development of the Geant 4 simulation toolkit has occurred, which will culminate in a major release at the end of 2013. This development includes the adoption of multi-threading, the extension and improvement of physics models, improvements to the geometry modeler with a revised implementation of most geometrical primitives, advances in visualization and graphical user interfaces (GUI), the move from GNU make to CMake and the extension and automation of the Geant 4 testing suite. The reasons for and implementation of multi-threading will be discussed. Certain electromagnetic and hadronic model extensions will also be discussed along with their effects on calorimeter results. Finally, visualization and GUI improvements will be highlighted along with the new configuration, build and testing systems.
