Parallel Algorithms In subject area: Computer Science Parallel algorithms refer to a computational approach where multiple solution points or populations of solutions are utilized at each iteration of the algorithm. By employing parallel processors, these algorithms significantly enhance the speed of ...
Moved more parallel algorithms into ParallelAlgorithms name space Feb 18, 2024 ParallelMergeSort.h Updating top-level application to include bundling example May 11, 2024 ParallelMergeSortBenchmark.cpp Fixed benchmarking to support arrays > 4 GigaElements (i.e. 64-bit) ...
Thrust is the C++ parallel algorithms library which inspired the introduction of parallel algorithms to the C++ Standard Library. Thrust’s high-level interface greatly enhances programmer productivity while enabling performance portability between GPUs and multicore CPUs. It builds on top of established ...
Examples − Parallel quick sort, sparse matrix factorization, and parallel algorithms derived via divide-and-conquer approach.Here, problems are divided into atomic tasks and implemented as a graph. Each task is an independent unit of job that has dependencies on one or more antecedent task. ...
3 The Algorithms 前面的讨论中自然出现的问题是:鉴于两阶段算法和重新分区算法适用于不同的分组选择性,我们能否以某种方式将两者合并以充分利用两者?以下部分介绍了三种方法来实现这一点。 3.1 Sampling Based Approach 如果我们可以比较精确的知道正在聚合的关系中的分组数,那么如果分组数较小,可以使用两阶段算法;如果...
In this paper we present an O(1/α log n )-time parallel algorithm for computing the convex hull of n points in 3 . This algorithm uses O(@#@ n 1+a ) processors on a CREW PRAM, for any constant 0 < α≤1. So far, all adequately documented parallel algorithms proposed for this...
[TOC] "Proximal Algorithms" 这一节,介绍并行算法的实现. 问题的结构 令$[n] = \{1, \ldots, n\}$. 给定$c \subseteq [n]$, 让$x_c \in \mathbb{R}^{|c|}$表示向量$x\in \mathb
Many algorithms in operations research and artificial intelligence are based on the backtracking principle, i.e., depth first search in implicitly defined trees. For parallelizing these algorithms, an efficient load balancing scheme is of central importa
