number of cores used by your jobs do not apply, but the material should still serve as an introduction to the basics of parallel programming.1 Overview of parallel processing computersThere are two basic flavors of parallel processing (leaving aside GPUs): distributed memory and shared memory. Wi...
Distributed DBMS 的用户不应该知道数据具体存储的地点,或者数据表本身是如何分片和复制的,对于用户来说,一个 SQL 在 Distributed DBMS 上运行的效果应该和在单节点 DBMS 上运行的效果等价。 Database Partitioning 既然要做 Distributed DBMS,势必要将数据库的资源分布到多个节点上,如磁盘、内存、CPU,这就是广义的分...
分布式内存架构(Distributed Memory):如计算集群,多个独立计算节点通过网络通信 共享内存架构(Shared Memory):如多核处理器,多个计算单元共享同一内存地址空间 第一个更大,通常叫做集群,就是一个机房好多机箱,每个机箱都有内存处理器电源等一些列硬件,通过网络互动,这样组成的就是分布式。 第二个是单个主板有多个处理器...
Distributed DBMSs 容错问题,避免单节点故障影响整个系统 System Architectures system architecture指的是distrubuted system的内存与disk的分布,以及cpu是如何去访问这些内存与disk。architecture能够影响cpu如何去存取database中的数据 shared everything已经算不上是分布式数据库了,一般是在自己的电脑上测试集群 Shared Memor...

这8堂关于分布式系统的课构成了《Concurrent and Distributed Systems》的后半部分。前半部分的重点是在同一台计算机上运行的多个进程或线程之间的并发,而后半部分则进一步研究了由多个通信计算机组成的系统。 在一台计算机上的并发也被称为 shared-memory concurrency共享内存并发,因为在同一进程中运行的多个线程可以访问...

There are several programming libraries which allow the programmer access to a distributed shared memory computer where machines over a network act as if they were part on one contiguous system. There has, however, not been wide-spread use of these libraries at the time of writing. 3. MPI im...

Each core chapter is devoted to one topic, covering reliable broadcast, shared memory, consensus, and extensions of consensus. For every topic, many exercises and their solutions enhance the understanding This book represents the second edition of "Introduction to Reliable Distributed Programming". Its...
