Concurrency vs Parallelism Concurrency and parallelism are two concepts that are related to each other, but are not entirely equivalent. In the program, concurrency emphasizes the combination of independently executed programs, while parallel emphasis is performed on simultaneous computation tasks [1]. The number of computer cores determines the ability of parallel computing, people as "single-core" animals (except

How the server program improves concurrency: Multi-process, multi-threaded model, this mode is now basically not Using multiplexing (such as actor-mode Epoll, Proactor-mode IOCP, etc.) + callback structure, this model not only does not conform to people's sequential thinking habits, but also error-prone. With the use of a co-process (lightweight threading, the cost of creating and destroying it is very

When you are finished, under the "gopath\src\github.com\" path, the Beego folder can see the subordinate Bee folder. At the same time, in the Gopath path of the src sibling bin, there is "Bee.exe" file. Step three, using the Bee tool to generate the framework engineering code In start, locate the command prompt, right-run as administrator, enter the SRC path

The go language is now relatively ripe for development. There is a lot of information on the Internet, this article does not repeat the installation, configuration, operation, grammar-related knowledge, because these are not more clear and convenient than the official website. It's just a little bit of the go language and other languages are not the same place, to help you quickly avoid the pit and change thinking.

First, learning ideasTwo days to learn Golang, but this time is not read, directly write code first.We often get used to reading while learning to write code, but found that the process is relatively slow, so I first want to write code,While writing and checking. As far as we know, web apps are generally based on the MVC framework, so I can write the data layer first, binate writeDatabase check data start,

Introduction Golang provides goroutine fast implementation of concurrent programming, in the real world, if the code in Goroutine consumes a lot of resources (CPU, memory, bandwidth, etc.), we need to speed up the program to prevent Goroutine from exhausting the resources.Take the following pseudo-code example to see how gorou

Busterwood.channels is an open-source library of channels implemented on C #. By using this class library, we can implement channel programming like Golang and Goroutine in the C # language.Here we introduce 3 examples of simple channels.

I. Concepts Channel is the communication mode between goroutine provided by golang language. Goroutine runs in the same address space, so the shared memory access must be synchronized. So how does goroutine communicate data? Go provides a good communication mechanism channel. A channel can be analogous to a two-way channel in a Unix shell: it can be used to send or receive values. These values can only be of a specific type: channel type. When definin
