Q. Suppose an operating system maps user-level threads to the kernel utilizing the many-to-many model where the mapping is done through the use of LWPs. In addition the system allows program developers to create real-time threads. Is it essential to bind a real-time thread to an LWP?
Answer: Yes or else a user thread may have to compete for an available LWP prior to being actually scheduled. Through binding the user thread to an LWP there is no latency while waiting for an available LWP the real-time user thread can be scheduled immediately.
