一种节能的并行混合等离子体求解器
An Energy Conserving Parallel Hybrid Plasma Solver
摘要：
我们研究了混合等离子体求解器在离子束测试问题上的性能。并行求解器在空间上基于单元中心有限差分，在时间上基于预测-校正蛙跳格式。在FLASH软件框架下实现。结果表明，求解器保存能量以及随着时间的推移，并行化是有效的（它表现出弱缩放）。
英文摘要：
We investigate the performance of a hybrid plasma solver on the test problem of an ion beam. The parallel solver is based on cell centered finite differences in space, and a predictor-corrector leapfrog scheme in time. The implementation is done in the FLASH software framework. It is shown that the solver conserves energy well over time, and that the parallelization is efficient (it exhibits weak scaling).
