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...
Study for Go ! Chapter seven - Concurrency 1. What is concurrency ? concurrency vs parallelism 并发:逻辑上具备同时处理多个任务的能力 并行:物理上在同一时刻执行多个并发任务 通常说的程序是并发设计的,也就是说它允许多个任务同时执行,但实际上并不一定真的在同一时刻发生 单核处理器以间隔方式执行 并行则...
Parallelism: Physically performing multiple tasks simultaneously using several independent resources . Go's Approach to Concurrency The Go programming language introduces a particularly elegant way to handle concurrency, emphasizing ease of use and performance. It does this usinggoroutines: lightweight thread...

shared memory concurrency涉及三个方面: parallelism, performance和correctnesss. 并行(Parallelism) 并行可加速计算. 通常采用两种方式[5]:partitioning: 将数据分割为若干由不同worker管理的partition, 可并行处理不同的partition. pipelining: 将任务分为若干彼此衔接的stage, 构成pipeline; stage之间通过共享存储或消息传...
But consequently, coroutines don’t necessarily provide parallelism, even on a multi-core system. 6.2. Kotlin Coroutine in Action Kotlin provides many coroutine builders to create a coroutine, like launch, async, and runBlocking. Further, coroutines in Kotlin are always bound to a coroutine scope...
