Research Abstract |
Geant4 is a comprehensive particle physics simulation package that tracks particles passing through and interacting with matter . As more detailed and complex simulations are required in different application domains, there is much interest in adapting the code for parallel architectures. This work is a CUDA port of the core Geant4 algorithm, and tracks many particles in parallel on the GPU. The capabilities of GPU architectures provide an opportunity to enhance the performance of Geant4 applications. Benchmark tests shows 30-40 speedup compared to the single-threaded CPU version.
