稠密颗粒流空间靶是我国加速器驱动次临界(ADS)工程中选择的一种新靶概念。为了研究和开发这种靶概念,开发了一个专用的蒙特卡罗(Monte Carlo)程序GMT来模拟研究束-靶相互作用。由于目标几何形状的复杂性,粒子轨迹的MC模拟的计算成本非常昂贵。因此,提高计算效率将是至关重要的密颗粒目标的详细MC模拟研究。本文介绍GMT程序的特殊设计及其高效性能。此外,GPU加速的spectrometer模型的加速潜力进行了讨论。
The dense granular flow spallation target is a new target concept chosen for the Accelerator-Driven Subcritical (ADS) project in China. For the R&D of this kind of target concept, a dedicated Monte Carlo (MC) program named GMT was developed to perform the simulation study of the beam-target interaction. Owing to the complexities of the target geometry, the computational cost of the MC simulation of particle tracks is highly expensive. Thus, improvement of computational efficiency will be essential for the detailed MC simulation studies of the dense granular target. Here we present the special design of the GMT program and its high efficiency performance. In addition, the speedup potential of the GPU-accelerated spallation models is discussed.
