论文摘要
我们讨论了晶格Boltzmann（LB）计算的艺术状况，特别关注能够应对即将举行的Exascale挑战的潜在LB方案。在回顾了LB计算的基本概念之后，我们讨论了当前的技术，以提高平行机上LB代码的性能，并说明Petascale范围内选定的前沿应用程序。最后，我们提出了一些有关如何改善当前大规模LB模拟中的通信/计算重叠的想法，以及耐故障LB方案的可能策略。
We discuss the state of art of Lattice Boltzmann (LB) computing, with special focus on prospective LB schemes capable of meeting the forthcoming Exascale challenge. After reviewing the basic notions of LB computing, we discuss current techniques to improve the performance of LB codes on parallel machines and illustrate selected leading-edge applications in the Petascale range. Finally, we put forward a few ideas on how to improve the communication/computation overlap in current large-scale LB simulations, as well as possible strategies towards fault-tolerant LB schemes.
