现在我们准备做第一个作业Lab1啦 wjk大神也在做6.824,可以参考大神的笔记https://github.com/zzzyyyxxxmmm/MIT6824_Distribute_System Part I The Map/Reduce implementation you are given is missing some pieces. Before you can write your first Map/Reduce function pair, you will need to f

本节内容:Lect 2 RPC and Threads 线程:Threads allow one program to (logically) execute many things at once.The threads share memory. However, each thread includes some per-thread state: program counter, registers, stack. 下面以go语言写一个爬虫作为例子来介绍线程: Go example:
前言 The Paxos algorithm, when presented in plain English, is very simple. ------ Lamport,<Paxos Made Simple> Unfortunately, Paxos is quite difficult to understand, in spite of numerous attempts to make it more approachable. ------ Diego Ongaro,<In

MapReduce是Google在2004年发表的论文<MapReduce: Simplified Data Processing on Large Clusters>中提出的一个用于分布式的用于大规模数据处理的编程模型. 原理 MapReduce将数据的处理分成了两个步骤,Map和Reduce.Map将输入的数据集拆分成一批KV对并输出,对于每一个<k1, v1>,Map将输出一批<k2, v2>:Reduce将Map对Map中产生的结果进行汇总,对于每一个<k
