WebMay 18, 2024 · Go’s concurrency model allows you to deploy workloads across multiple CPU cores, making it a very efficient language: package main import ( "fmt" "time" ) func f(from string) { for i := 0; i < 3; i++ { fmt.Println(from, ":", i) } } func main() { f("direct") go f("goroutine") time.Sleep(time.Second) fmt.Println("done") }
WebThe memory model ensures that after two concurrent writes, v=a and v=b, where v is a word-sized variable, a read of v will observe either a or b, but not an arbitrary ("out of thin air") value, so the behavior is far from "undefined" as it is understood in C. ...
