Kuidas toimub nelja gorutini jaotamine neljale protsessori tuumale nende käivitamisel?

In Go, the Goroutine scheduler distributes goroutines across system threads (M), which are in turn bound to CPU cores.

If you have 4 goroutines and 4 CPU cores, the scheduler can assign each goroutine to a separate core at startup, enabling parallel execution. This is possible if the environment variable GOMAXPROCS is set to 4 (by default, in modern Go versions, it equals the number of available cores).

Example:

runtime.GOMAXPROCS(4) // sets the number of available threads to 4

for i := 0; i < 4; i++ {
    go func(id int) {
        fmt.Printf("Goroutine %d started\n", id)
        // work
    }(i)
}

The Go scheduler will distribute goroutines across threads that can run on different cores, allowing efficient use of multiprocessor systems. However, the exact distribution depends on system load and the internal scheduler.
