三维自适应有限元方法（FEM）的并行实现在最近的集群SMP处理动态负载增加，由于自适应细化，这可能会导致负载不平衡。此外，自适应FEM的不规则行为会导致进一步的影响，如变化的缓存效应或通信成本，这使得重新分配策略更加复杂。在本文中，我们调查这些影响和并行自适应有限元的性能行为的相互作用，并提出了最近SMP集群的几个性能结果。
The parallel implementation of 3-dimensional adaptive finite element methods (FEM) on recent clusters of SMPs has to deal with dynamic load increase due to adaptive refinement which might result in load imbalances. Additionally, the irregular behavior of adaptive FEM causes further impacts like varying cache effects or communication costs which make a redistribution strategy more complex. In this paper we investigate the interaction of these effects and the performance behavior of parallel adaptive FEM and present several performance results on recent SMP clusters.
