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. Thus, the developers don't need to program … See more Graph500 is the first benchmark for data-intensive supercomputing problems. This benchmark generates an edge tuple with two endpoints at first. Then the kernel 1 will constructs an … See more http://supertech.csail.mit.edu/papers/pbfs.pdf

WebOct 10, 2003 · We propose a practical parallel on-the-fly algorithm for enumerative LTL (linear temporal logic) model checking. The algorithm is designed for a cluster of workstations communicating via MPI (message passing interface). The detection of cycles (faulty runs) effectively employs the so called back-level edges. In particular, a parallel … WebMar 19, 2007 · Parallel Breadth-First Search (BFS) algorithms for ordered trees and graphs on a shared memory model of a Single Instruction-stream Multiple Data-stream computer are proposed. The parallel BFS algorithm for trees computes the BFS rank of eachnode of an ordered tree consisting of n nodes in time of 0(β log n ) when 0( n 1+1/β ) processors are ... WebAug 11, 2005 · In this work, we explore the design space of parallel algorithms for Breadth-First Search (BFS), a key subroutine in several graph algorithms. We present two highly-tuned par- allel approaches for BFS on large parallel systems: a level-synchronous strategy that relies on a simple vertex-based partitioning of the graph, and a two-dimensional ... cleaners sutherland shire
