SDN帮助大数据优化数据访问

SDN helps Big Data to optimize access to data

Yuankun Fu, Fengguang Song

摘要:

本章介绍了高性能计算(HPC)与大数据分析相结合这一新兴领域的最新技术。为了了解这个新领域,本章首先调查了将HPC与大数据集成的现有方法。接下来,本章介绍了几种优化解决方案,重点是如何最大限度地减少从计算密集型应用程序到分析密集型应用程序的数据传输时间,以及最大限度地减少端到端解决方案的时间。该解决方案利用SDN自适应地使用高速互连网络和高性能并行文件系统来优化应用性能。设计和开发了一个名为DataBroker的计算框架,以实现HPC与数据分析的紧密集成。多种类型的实验已经进行了显示不同的性能问题,在消息传递和并行文件系统,并验证所提出的研究方法的有效性。

英文摘要:

This chapter introduces the state-of-the-art in the emerging area of combining High Performance Computing (HPC) with Big Data Analysis. To understand the new area, the chapter first surveys the existing approaches to integrating HPC with Big Data. Next, the chapter introduces several optimization solutions that focus on how to minimize the data transfer time from computation-intensive applications to analysis-intensive applications as well as minimizing the end-to-end time-to-solution. The solutions utilize SDN to adaptively use both high speed interconnect network and high performance parallel file systems to optimize the application performance. A computational framework called DataBroker is designed and developed to enable a tight integration of HPC with data analysis. Multiple types of experiments have been conducted to show different performance issues in both message passing and parallel file systems and to verify the effectiveness of the proposed research approaches.
