存储、计算和通信:分布式计算中的基本权衡

Storage, Computation, and Communication: A Fundamental Tradeoff in Distributed Computing

Qifa Yan, Sheng Yang, Michèle Wigger

摘要:

我们考虑一个类似MapReduce的分布式计算系统。我们推导出一个下界的通信成本为任何给定的存储和计算成本。这个下限与我们最近提出的可实现的界限相匹配。其结果是,我们完全表征的存储,计算和通信之间的最佳权衡。我们的结果推广了Li等人的前一个结果,也考虑了计算的中间值的数量。

英文摘要:

We consider a MapReduce-like distributed computing system. We derive a lower bound on the communication cost for any given storage and computation costs. This lower bound matches the achievable bound we proposed recently. As a result, we completely characterize the optimal tradeoff between the storage, the computation, and the communication. Our result generalizes the previous one by Li et al. to also account for the number of computed intermediate values.
