Abstract

The invention relates to a width-first search algorithm-oriented acceleration device and method and a storage medium. The device comprises a memory module which is used for storing graph data and a search result, a execution unit module which is used for constructing a multi-stage assembly line according to the internal characteristics of the width-first-oriented search algorithm so as to executea traversal search task, a memory access multiplexing module which is used for processing a memory access request of the assembly line according to a set priority, a scheduling module which is used for distributing the response data of the memory module to an idle execution unit; and a control module which is used for controlling and managing each module. The method and the device can improve thecomputational efficiency of graph data processing.

Description

technical field [0001] The invention relates to the fields of big data, graph calculation and computer architecture, in particular to an acceleration method and device for a breadth-first search algorithm. Background technique [0002] In the fields of big data, graph computing, and computer architecture, graphs are the most commonly used data structure to describe the associated attributes of things. Many application scenarios in real life can be represented by graph structures, such as social networks, transportation networks, biological Information networks and knowledge graphs, etc. In order to meet the needs of graph applications and graph processing technologies, various graph algorithms emerge in endlessly. [0003] Breadth First Search (BFS) algorithm is a classic algorithm for solving graph traversal problems, and it is also the basis of many important graph algorithms. The basic idea is that, for the graph structure G=(V,E), the vertex set V and the edge set E, a...
