Description
A new project for advanced simulation technology in radiotherapy was launched on Oct.
2003 with funding of JST (Japan Science and Technology Agency) in Japan. The project
aim is to develop an ample set of simulation package for radiotherapy based on Geant4
in collaboration between Geant4 developers and medical users. They need much more
computing power and strong security for accurate and high-speed dose calculation and
therefore parallelism and gridify of Geant4 applications is an important issue for
our project. Some of LCG (LHC Computing Grid) middlewares were actually deployed and
enabled to share the computing resources and to control job between KEK and ICEPP. A
class library was developped for parallelization of existent Geant4-based application
as a part of Geant4 framework. One of our practical application was accelerated by
30 times uder 40 CPUs and then parallel efficiency is 67%. In this paper, we will
describe how to design and implement parallelization of Geant4 medical applications
and interface between our applications and Grid environment.
