海量图上的分布存储广度优先搜索

Distributed-Memory Breadth-First Search on Massive Graphs

Aydin Buluc, Scott Beamer, Kamesh Madduri, Krste Asanovic, David Patterson

摘要:

本章研究在分布式内存超级计算机上使用广度优先搜索顺序遍历大型图的问题。我们既考虑了传统的层次同步自顶向下算法,也考虑了最近发现的方向优化算法。我们分析了使用不同的本地数据结构,如CSR和DCSC,使节点内多线程,和图形分解,如1D和2D分解的性能和可扩展性的权衡。

英文摘要:

This chapter studies the problem of traversing large graphs using the breadth-first search order on distributed-memory supercomputers. We consider both the traditional level-synchronous top-down algorithm as well as the recently discovered direction optimizing algorithm. We analyze the performance and scalability trade-offs in using different local data structures such as CSR and DCSC, enabling in-node multithreading, and graph decompositions such as 1D and 2D decomposition.
