Locality-Based Relaxation: An Efficient Method for GPU-Based

WebGP-GPU, Parallel Computing, CUDA C, Dijkstra, BGL, Grid. 1. Introduction. In this paper, we examine the impact of copying data on the global acceleration of an algorithm in which tasks are shared between CPU and GPU. We use Dijkstra’s algorithm on the shortest path [1] to illustrate the problem. WebJun 12, 2024 · Dijkstra’s algorithm is an algorithm for finding the shortest path between nodes in a graph. The algorithm published in 1959 by Dutch computer scientist Edsger W. Dijkstra, can be applied on a weighted graph. Dijkstra’s original algorithm runtime is a quadratic function of the number of vertices. In this paper, I will investigate the parallel …
