If GOMAXPROCS=2 and two infinite loops with mathematical operations are running, will other goroutines be executed?

If GOMAXPROCS=2, it means that the Go scheduler can use 2 OS threads simultaneously to run goroutines.

If two infinite loops with intensive mathematical operations are running, they will occupy both threads completely, as they do not make blocking calls or I/O operations.

As a result, other goroutines will not be able to get CPU time, and their execution will be heavily delayed or almost stopped.

To solve such a situation, you need to either reduce the load in these loops, add points where goroutines call runtime.Gosched() or perform blocking operations, or increase GOMAXPROCS to give more threads to the scheduler.
