摘要：

计算机经济正在发生变化。今天，（1）一次数据库访问，（2）10字节的网络流量，（3）100，000条指令，（4）10字节的磁盘存储，（5）一兆字节的磁盘带宽之间的价格大致相当。这对如何构建互联网规模的分布式计算有影响：为了避免昂贵的网络流量，计算尽可能接近数据。

英文摘要：

Computing economics are changing. Today there is rough price parity between (1) one database access, (2) ten bytes of network traffic, (3) 100,000 instructions, (4) 10 bytes of disk storage, and (5) a megabyte of disk bandwidth. This has implications for how one structures Internet-scale distributed computing: one puts computing as close to the data as possible in order to avoid expensive network traffic.

An economic perspective on major cloud computing providers

Cloud computing can be defined as the outsourcing / renting of resources over the network. It has been regarded as an essential utility similar to electricity, water, telephone and sewerage utilities. Over the years, a number of providers have emerged that provide basic and advanced form of services for cloud computing. However, these providers employ their own nomenclature for marketing their specification and the range of services offered by them. This makes it very difficult for a common user to select a platform based on their requirements. This paper provides a comparison of different clo…

分布式系统简介

Introduction to Distributed Systems

自从第一台计算机诞生以来，计算已经经历了许多转变。技术的发展导致了快速和廉价的处理器的可用性，并且通信技术的进步导致了利润丰厚和高度熟练的计算机网络的可用性。其中，集中式网络有一个组件一直由用户共享。所有的资源都是可访问的，但是有一个控制点和一个故障点。20世纪70年代末，计算机技术和网络技术的结合产生了一种新的计算模式，称为分布式计算。分布式计算改变了计算的面貌，为不同领域的各种复杂问题提供了快速而精确的解决方案。如今，我们完全被信息时代所吸引，并且花费更多的时间通过互联网进行交流和收集信息。互联网不断地沿着几个量级发展，越来越多的终端系统以越来越多的不同方式进行通信。多年来，已经发展了几种方法来实现这些发展，从简单的数据共享到支持多种服务的高级系统。本文概述了分布式计算系统。本文首先讨论了分布式系统的定义、体系结构、特点以及各种分布式计算谬误。最后，讨论了客户机/服务器计算，万维网和分布式系统的类型。

Delay-Optimal Distributed Edge Computing in Wireless Edge Networks

By integrating edge computing with parallel computing, distributed edge computing (DEC) makes use of distributed devices in edge networks to perform computing in parallel, which can substantially reduce service delays. In this paper, we explore DEC that exploits distributed edge devices connected by a wireless network to perform a computation task offloaded from an end device. In particular, we study the fundamental problem of minimizing the delay of executing a distributed algorithm of the computation task. We first establish some structural properties of the optimal communication scheduling …

Software Defined Edge Computing for Distributed Management and Scalable Control in IoT Multinetworks

Recently, edge computing has emerged as a promising paradigm to support mobile access in IoT multinetworks. However, coexistence of heterogeneous wireless communication schemes brings about new challenges to the mobility management and access control in such networks. To maintain its computing continuum, Software-Defined Networking (SDN) architecture can be applied to the distributed edge networks, which provides consistent frameworks for mobility management and creates secure mechanisms for access control. In this paper, we first review the state-of-the-art SDN technology and its applications…

Compiler Design for Distributed Quantum Computing

In distributed quantum computing architectures, with the network and communications functionalities provided by the Quantum Internet, remote quantum processing units (QPUs) can communicate and cooperate for executing computational tasks that single NISQ devices cannot handle by themselves. To this aim, distributed quantum computing requires a new generation of quantum compilers, for mapping any quantum algorithm to any distributed quantum computing architecture. With this perspective, in this paper, we first discuss the main challenges arising with compiler design for distributed quantum compu…

Optimal Control of Distributed Computing Networks with Mixed-Cast Traffic Flows

Distributed computing networks, tasked with both packet transmission and processing, require the joint optimization of communication and computation resources. We develop a dynamic control policy that determines both routes and processing locations for packets upon their arrival at a distributed computing network. The proposed policy, referred to as Universal Computing Network Control (UCNC), guarantees that packets i) are processed by a specified chain of service functions, ii) follow cycle-free routes between consecutive functions, and iii) are delivered to their corresponding set of destina…

On the Robustness of Distributed Computing Networks

Traffic flows in a distributed computing network require both transmission and processing, and can be interdicted by removing either communication or computation resources. We study the robustness of a distributed computing network under the failures of communication links and computation nodes. We define cut metrics that measure the connectivity, and show a non-zero gap between the maximum flow and the minimum cut. Moreover, we study a network flow interdiction problem that minimizes the maximum flow by removing communication and computation resources within a given budget. We develop mathema…
