Go 的并行机制使其非常容易编写多核和网络应用。Go 语言的并发模型基于 CSP(Communicating sequential processes, 参见维基百科 [CSP](http://en.wikipedia.org/wiki/Communicating_Sequential_Processes))。Go 提供了 goroutines(并发执行), channels(同步和通信), select(多路并发控制) 等特性来支持并发编程。Go 的发明者之一 Rob Pick 在他的一篇讲稿([Concurrency is not Parallelism(it's better)](http://concur.rspace.googlecode.com/hg/talk/concur.html))中提到：

Rob 认为并发是程序本身的一种特性，程序被分为多个可独立执行的部分，而各个可独立执行的片段通过通信手段进行协调（后文会提到），而并行则是程序的计算过程（不同的计算过程可能相关联）同时执行。

Rob Pike 的观点是： 并发是一次处理(dealing with)很多事情，而并行是一次做(doing)很多事情.(注: 英文词汇的表达也很微妙)[原文](http://concur.rspace.googlecode.com/hg/talk/concur.html#slide-5)是如下：

即我们可以利用并发的手段去构建一种解决方案来解决那些有可能被并行处理的问题。

作者在本文中还[提到](http://concur.rspace.googlecode.com/hg/talk/concur.html#slide-7)，设计并发程序时应该将程序分为多个执行片段，使得每个片段可以独立执行。不同执行片段通过通信(Communication )来进行协调。因此 Go 的并发模型基于 CSP: C. A. R. Hoare: Communicating Sequential Processes (CACM 1978)
