k 维(k-d)树是数据工程和所谓的大数据领域中最重要的数据结构之一。在本文中,我们提出了一种并行构建 k-d 树的方案。由于构建平衡的 k-d 树需要有效的预排序,因此我们还开发了并行堆排序算法。所提出的方案比顺序构建 k-d 树快 3.59 倍。
k-dimensional (k-d) trees are one of the most important data structures in the fields of data engineering and so-called Big Data. In this paper we propose a scheme parallelizing the construction of a k-d tree. Since efficient presorting is required for constructing a balanced k-d tree, we also developed a parallelized heapsort algorithm. The proposed scheme is 3.59 times faster than sequential construction of a k-d tree.
