基于GPU并行的一种快速常规态近场动力学算法
A state based peridynamic algorithm based GPU parallelism
摘要
Abstract
This paper utilizes the parallel CUDA programming technology of GPU to study the parallel solution method of peridynamics.A cost-effective and high-performance peridynamics simulation framework,PD-General,has been designed.This analytical framework can accurately simulate ordinary state based peridynamics problems at an efficient computational rate.Compared with serial programs and OpenMP parallel programs,PD-General has achieved a maximum speedup of 800 times and 100 times,respectively.In conventional million-level particle simulations,performing 4000 iterations,the computation can be completed within 5 minutes in single precision and within 20 minutes in double precision.In the largest scale exploration,the program has achieved a computation of 69,856,200 iterations for a 1000-step two-dimensional uniaxial tension problem based on the ordinary state based peridynamics in single precision,taking only two minutes.关键词
