摘要:

分布式计算由于具有高可靠性、可扩展性、计算速度和成本效益等优点,已经成为大规模任务计算的常用方法。然而,分布式计算面临着与通信负载和离散效应相关的关键问题。特别地,计算节点需要彼此交换中间结果以便计算最终结果,并且这显著增加了通信开销。此外,分布式计算网络可以包括间歇性地运行得更慢的离散节点。这导致执行计算任务所需的总时间更长,从而限制了分布式计算的性能。为了解决这些问题,编码的分布式计算(CDC),即,编码理论技术和分布式计算的组合最近已被提出作为有希望的解决方案。编码理论技术已经证明在WiFi和蜂窝系统中有效地处理信道噪声。因此,CDC可以显著降低通信负载,减轻掉队者的影响,提供容错性、隐私性和安全性。在本调查中,我们首先介绍CDC的基本原理,然后是基本的CDC方案。然后,我们回顾和分析了一些CDC的方法,提出了减少通信成本,减轻掉队的影响,并保证隐私和安全。此外,我们提出并讨论了CDC在现代计算机网络中的应用。最后,我们强调了与疾病预防控制相关的重要挑战和有前途的研究方向

英文摘要:

Distributed computing has become a common approach for large-scale computation of tasks due to benefits such as high reliability, scalability, computation speed, and costeffectiveness. However, distributed computing faces critical issues related to communication load and straggler effects. In particular, computing nodes need to exchange intermediate results with each other in order to calculate the final result, and this significantly increases communication overheads. Furthermore, a distributed computing network may include straggling nodes that run intermittently slower. This results in a longer overall time needed to execute the computation tasks, thereby limiting the performance of distributed computing. To address these issues, coded distributed computing (CDC), i.e., a combination of coding theoretic techniques and distributed computing, has been recently proposed as a promising solution. Coding theoretic techniques have proved effective in WiFi and cellular systems to deal with channel noise. Therefore, CDC may significantly reduce communication load, alleviate the effects of stragglers, provide fault-tolerance, privacy and security. In this survey, we first introduce the fundamentals of CDC, followed by basic CDC schemes. Then, we review and analyze a number of CDC approaches proposed to reduce the communication costs, mitigate the straggler effects, and guarantee privacy and security. Furthermore, we present and discuss applications of CDC in modern computer networks. Finally, we highlight important challenges and promising research directions related to CDC
