简介:译 | Concurrency is not Parallelism Concurrency vs Parallelism 如果你看看今天的编程语言,可能会发现这个世界是面向对象的,但实际上并非如此,世界是并行的。你通过网络等等,从最底层(例如:多核计算机)获取所有的东西,一路攀升到了解星球、宇宙。世界上所有的东西都在同时发生,但我们拥有的计算工具实际上并不擅...
Rob pike发表过一个有名的演讲《Concurrency is not parallelism》(https://blog.golang.org/concurrency-is-not-parallelism), 演讲胶片在talks.golang.org中可以找到(https://talks.golang.org/2012/waza.slide#1), 演讲视频地址 :https://vimeo.com/49718712 以下是根据视频转换的文本信息。 if you looked a...
最后,关于Concurrency is not parallelism这个talk再多说点。自从这个talk出来,直接引爆了一堆讨论并发vs并行的文章,并且无一例外提到这个talk,甚至有的文章直接用它的slide里的图片来说明。 Although there’s a tendency to think that parallelism means multiple cores,modern computers are parallel on many different...
在Rob Pike的《Concurrency is not Parallelism》(http://talks.golang.org/2012/waza.slide)中说到,我们的世界是Parallelism,比如网络,比如大量独立的个人。但是需要协作的。所以就有了并发。很多人认为并发很COOL,认为并发就是并行。但是这种观念在ROB PIKE看来是错误的。比如之前有个人写了一个质数筛选的程序,然后...

2. What is Parallelism? Parallelism does not require two tasks to exist. It, literally, physically runs parts of tasks OR multiple tasks, at the same time using the multi-core infrastructure of the CPU, by assigning one core to each task or sub-task. ...

It is not parallelism. Concurrency is not paralleism Concurrency is not paralleism, although it enables parallelism. If you have only one processor, your program can still be concurrent but it cannot be parallel. On the other hand, a well-written concurrent program might run efficiently in para...
Concurrency is different than parallelism. And it is better onspecificscenarios that involve a lot of waiting. Because of that, it generally is a lot better than parallelism for web application development. But not for everything. So, to balance that out, imagine the following short story: ...
