Parallel breadth-first search

The breadth-first-search algorithm is a way to explore the vertices of a graph layer by layer. It is a basic algorithm in graph theory which can be used as a part of other graph algorithms. For instance, BFS is used by Dinic's algorithm to find maximum flow in a graph. Moreover, BFS is also one of the kernel … See more In the conventional sequential BFS algorithm, two data structures are created to store the frontier and the next frontier. The frontier contains all vertices that have the same distance (also called "level") from the source … See more In the distributed memory model, each processing entity has its own memory. Because of this, processing entities must send and receive … See more • Parallel algorithm • Distributed algorithm See more As a simple and intuitive solution, the classic Parallel Random Access Machine (PRAM) approach is just an extension of the sequential … See more Compared to parallel BFS with distributed memory, shared memory provides higher memory-bandwidth and lower latency. Because all processors share the memory together, all of them have the direct access to it.

WebA tag already exists with the provided branch name. Many Git commands accept both tag and branch names, so creating this branch may cause unexpected behavior. WebBreadth-first search is an algorithm for exploring the vertices and edges of a directed graph, beginning from a particular "starting vertex". It's a simple sequential algorithm, but making it run well in parallel is challenging.
