摘要

针对分子动力学问题，我们定制了一个动态负载均衡器。均衡器是分布式的，它不需要长距离的进程间通信，只需要相邻处理器之间的通信。当系统保持适度的不平衡水平时，它可以准确地实现显著的时间改进。只有当系统没有达到最小阈值不平衡时，开销才会成为问题。

Distributed load balancing for molecular dynamics simulations

We customize a dynamic load balancer to the molecular dynamics problem. The balancer is distributed, it requires no long-distance inter-process communications but only those among adjacent processors. It works accurately achieving significant time improvements when the system maintains moderate imbalance levels. The overhead is a problem only when the system does not achieve a minimum threshold imbalance.
