AI总结：
本文比较了三种相对论粒子推动器在计算时间和精度方面的表现，提出适应参数以帮助选择合适的积分器。
摘要：
相对论粒子推动器的性能长期以来一直是计算等离子体物理领域关注的话题，尤其是在粒子-网格方法的视角下。以往的研究主要针对超相对论极限情况。本文利用自编代码，研究了Boris、Vay和Higuera-Cary三种粒子推动器在低、高和超相对论粒子情况下的核心运行时间。随后，从准确性和误差角度比较了这三种积分器。然后提出一个适应参数，可作为确定特定模拟设置下哪种方法更合适的一站式值。希望通过了解这些细节，根据具体问题选择积分器会更加容易。
英文摘要：
The performance of relativistic particle pushers has long been a topic of interest in the field of computational plasma physics, particularly from the point of view of the particle-in-cell approach. Previous works undertaken to compare such integrators have predominantly targeted the ultra-relativistic regime. In this paper, we utilize a custom-built code to study the core run-times of the Boris, the Vay, and the Higuera-Cary particle pushers for low-, high-, and ultra-relativistic particles. This is followed by a comparison of the three integrators in terms of accuracy and error. A fitness parameter is then proposed that can serve as a one-stop value to determine which method is more suitable for a particular simulation setup. It is hoped that through knowledge of such intricacies, the choice for the integrator will be easier to make depending on the problem at hand.
