Kuidas toimub goroutine'ide täitmise tasakaalustamine programmis?

Balancing the execution of goroutines in Go is handled by the scheduler built into the runtime. The scheduler distributes goroutines among available system threads (OS threads) using an M:N model, where M is the number of threads and N is the number of goroutines.

Main points:

• There are many goroutines, they are lightweight and switch without OS involvement.
• The scheduler uses algorithms similar to cooperative multitasking, but with the ability to interrupt.
• Goroutines are assigned to threads, and if a goroutine blocks (e.g., on I/O), the scheduler switches to another.

Example:

func main() {
    for i := 0; i < 10; i++ {
        go func(id int) {
            fmt.Println("Goroutine", id)
        }(i)
    }
    time.Sleep(time.Second) // Wait for goroutines to finish
}

Here, the scheduler will distribute 10 goroutines across available threads, ensuring balance and efficient CPU utilization.
