一种适用于大范围空气簇射模拟的简化格式

A Simple Parallelization Scheme for Extensive Air Shower Simulations

B. T. Stokes, R. Cady, D. Ivanov, J. N. Matthews, G. B. Thomson

摘要:

一个简单的方法,广泛的空气簇射模拟并行化。在固定的高度步长上模拟阵雨。在每一步中,低于指定能量阈值的子粒子被虹吸出来并制成表格以供进一步模拟。一旦整个簇射被制成表格,产生的粒子列表被连接并分成单独的列表文件,每个列表文件都具有类似的投影计算时间。然后将这些列表放置在计算集群上,当计算资源变得可用时,可以在其中以零碎的方式完成模拟。模拟完成后,输出将重新组合为完整的空气簇射模拟。原始模拟程序(在本例中为CORSIKA)在此过程中没有任何改变。验证是通过比较10^(16.5)eV的簇射产生和没有并行化。

英文摘要:

A simple method for the parallelization of extensive air shower simulations is described. A shower is simulated at fixed steps in altitude. At each step, daughter particles below a specified energy threshold are siphoned off and tabulated for further simulation. Once the entire shower has been tabulated, the resulting list of particles is concatenated and divided into separate list files where each possesses a similar projected computation time. These lists are then placed on a computation cluster where the simulation can be completed in a piecemeal fashion as computing resources become available. Once the simulation is complete, the outputs are reassembled as a complete air shower simulation. The original simulation program (in this case CORSIKA) is in no way altered for this procedure. Verification is obtained by comparisons of 10^(16.5) eV showers produced with and without parallelization.
