新的深度优先布局提升 $k^2$-树的压缩和性能

研究人员开发了新的 $k^2$-树深度优先表示法,以提高其效率和压缩率,解决了传统层级布局糟糕的缓存性能问题。提出的方法包括 EDF-1、BP、CEDF 和 CBP,它们利用深度优先布局和一种线性时间压缩技术来处理相同的子树。在网页图、Wikidata 和合成数据上的实验结果表明,这些新的表示法具有竞争力,其中 CEDF 提供了最佳压缩效果,EDF-1/CEDF 持续减少峰值内存使用量,从而提高了矩阵运算的性能。 AI

    $k^2$-树的扩展深度优先表示

    In this paper, we study static, computation-friendly, lossless compression formats for graphs, focusing on memory locality and operational efficiency of $k^2$-trees. We observe that their traditional level-wise layouts suffer from poor cache performance due to weak locality, espe…
