Consider a multiprocessor system and a multithreaded program written using the many-to-many threading model. Let the number of user-level threads in the program be greater than the number of processors in the system. What relationship is expected for the performance of the system (in terms of total CPU utilization across the multiple processors) in the following scenarios. a. The number of kernel threads allocated to the program is less than the number of processors. b. The number of kernel threads allocated to the program is equal to the number of processors. c. The number of kernel threads allocated to the program is greater than the number of processors but less than the number of user-level threads.
