PeriPy - A high performance OpenCL peridynamics package

This paper presents a lightweight, open-source and high-performance python package for solving peridynamics problems in solid mechanics. The development of this solver is motivated by the need fast analysis tools to achieve large number simulations required `outer-loop' applications, including sensitivity analysis, uncertainty quantification optimisation. Our software toolbox utilises heterogeneous nature OpenCL so that it can be executed on any platform with CPU or GPU cores. We illustrate use through range industrially examples, which should enable other researchers build extend their own applications. Step improvements execution speed functionality over existing techniques are presented. A comparison between an implementation literature presented, tested benchmarks hundreds thousands tens millions nodes. demonstrate scalability GeForce RTX 2080 TiGPU from NVIDIA, memory-bound limitations analysed. In all test cases, 1.4 10.0 times faster than similar literature. particular, improvement has been achieved utilising local memory GPU.
