Description
The Geant4 Collaboration released a new generation of the Geant4
simulation toolkit (version 10.0) in December 2013, and continues
to improve its physics, computing performance and usability. This
presentation will cover the major improvements made since version
10.0. The physics evolutions include improvement of the Fritiof
hadronics model, extension of the INCL++ model to higher energy,
extension of the data-driven low-energy neutron model approach to
proton and light ions, extension of radioactive decay modes to
include proton emission and double beta decay, introduction of
phonon physics, a first implementation of particle-matter
interactions dealing with crystal lattice structure, improvements
of multiple-scattering for displacement at volume boundary, and
extension of low energy electromagnetic processes in DNA scale.
Extension and improvement of the unified solid library will provide
more functionality and better computing performance. The continued
effort to reduce memory consumption per thread allows for massive
parallelism of large applications in the multithreaded mode.
Toolkit usability is improved with an evolved real-time
visualization in multithreaded mode, a new web-based visualization
driver, enhancements in histogramming tool in particular in
multithreaded mode, and additional APIs for easier integration with
Intel TBB and MPI. In addition, the Collaboration has extended its
platform support to the Xeon Phi coprocessors. A redesigned physics
validation tool based on modern web technologies will ease users'
access to routinely performed validations. We will also discuss
our short and long term development perspectives.
