AI总结:

本文综述了分层低秩近似方法的最新进展,并通过简单代表性测试案例比较了两种优化实现的性能差异,探讨了计算与内存的权衡。

摘要:

近年来,分层低秩近似方法的研究工作显著增加,多个先前不相交的领域对此产生了兴趣。本文旨在从分析和代数角度全面回顾该领域近期的进展,并通过一些简单但具有代表性的测试案例,比较两种高度优化的实现方法。我们从计算与内存的权衡角度分类了该领域的最新进展,这种分类在该领域此前很少被详细讨论。基准测试显示,不同方法在内存消耗和性能上存在显著差异。

英文摘要:

There has been a large increase in the amount of work on hierarchical low-rank approximation methods, where the interest is shared by multiple communities that previously did not intersect. This objective of this article is two-fold; to provide a thorough review of the recent advancements in this field from both analytical and algebraic perspectives, and to present a comparative benchmark of two highly optimized implementations of contrasting methods for some simple yet representative test cases. We categorize the recent advances in this field from the perspective of compute-memory tradeoff, which has not been considered in much detail in this area. Benchmark tests reveal that there is a large difference in the memory consumption and performance between the different methods.
