The Go scheduler
The OS kernel scheduler is responsible for the execution of the threads of a program. Similarly, the Go runtime has its own scheduler, which is responsible for the execution of the goroutines using a technique known as m:n scheduling, where m goroutines are executed using n OS threads using multiplexing. The Go scheduler is the Go component responsible for the way and the order in which the goroutines of a Go program get executed. This makes the Go scheduler a really important part of the Go programming language. The Go scheduler is also executed as a goroutine.
Be aware that as the Go scheduler only deals with the goroutines of a single program, its operation is much simpler, cheaper, and faster than the operation of the OS kernel scheduler.
Go uses the fork-join concurrency model. The fork part of the model, which should not be confused with the fork(2) system call, states that a child branch can be created at any point of a program. Analogously...
