We present an integrated study on the scalability and performance of particle-in-cell (PIC) code simulations on CPU and GPU architectures of high parallelization focused on target normal sheath acceleration (TNSA) and laser wakefield acceleration (LWFA) experiments. The developed models follow the experimental specifications of the high-power lasers systems hosted at the infrastructures of the Institute of Plasma Physics & Lasers of the Hellenic Mediterranean University in Crete, Greece and the Extreme Light Infrastructure - Nuclear Physics in Romania. The simulations are implemented on the High-Performance Computer for Advanced Research Information System of the Greek National Infrastructures for Research and Technology. Two representative experiments for TNSA and for LWFA are initially simulated by 2D models with the minimum computational resource demands and the results are used as a reference for the scalability and performance investigation. We further extend our study ...

针对大功率激光系统，在CPU和GPU架构上实现正常的鞘层加速和激光尾场加速粒子内仿真性能

我们针对目标并行鞘层加速度（TNSA）和激光尾波场加速度（LWFA）实验，对高度并行化的CPU和GPU架构上的单元中粒子（PIC）代码模拟的可伸缩性和性能进行了综合研究。开发的模型遵循希腊克里特岛希腊地中海大学等离子物理与激光研究所和罗马尼亚的“极端光基础设施-核物理”基础设施上托管的高功率激光系统的实验规范。模拟在希腊国家研究和技术基础设施的高级研究信息系统高性能计算机上实现。最初使用2D模型以最小的计算资源需求对TNSA和LWFA进行了两个代表性实验，并将结果用作可伸缩性和性能研究的参考。我们进一步扩大研究范围...
