GPU上的Monte Carlo积分

Monte Carlo integration on GPU

J. Kanzaki

摘要:

我们使用一个图形处理单元(GPU)的快速计算蒙特卡罗积分。两个广泛使用的Monte Carlo积分程序,VEGAS和BASES,在GPU上并行化。利用LHC的$W^{+}$和多胶子产生过程,我们测试了FORTRAN和C语言程序在CPU上和GPU上的积分截面和执行时间。综合结果在统计误差范围内相互吻合。程序在GPU上的执行速度比C快50倍左右,比原来的FORTRAN程序快60倍以上。

英文摘要:

We use a graphics processing unit (GPU) for fast computations of Monte Carlo integrations. Two widely used Monte Carlo integration programs, VEGAS and BASES, are parallelized on GPU. By using $W^{+}$ plus multi-gluon production processes at LHC, we test integrated cross sections and execution time for programs in FORTRAN and C on CPU and those on GPU. Integrated results agree with each other within statistical errors. Execution time of programs on GPU run about 50 times faster than those in C, and more than 60 times faster than the original FORTRAN programs.
