Table provides the details of three processes that are executed in a uniprocessor system that supports multithreading. Process P1 has two threads while processes P2 and P3 have one thread each. Time slicing is exploited to carrying out the scheduling. It takes 7 time units to complete a system call. You can assume that dispatching is effortless. The event request made by thread P1-T1 at time unit 1 is for the readiness of the result obtained after executing thread P1-T2 for 2 time units. Process-thread Required time unit System call made Time of arrival P1-T1 Event request @1 0 P1-T2 0.01 P2-T1 P3-T1 3 5 5 8 System call @2 0.02 0.03 (a) Threads are handled as user-level threads in the system. For each process, 4 time units are allocated each time. In the slots allocated to a particular process, for each thread of the process, 1 time unit is allocated each time. Derive the timing diagram that shows how different processes and threads change their states. (b) Threads are handled as kernel-level threads in the system. For each kernel-level thread, 4 time units are allocated each time. Derive the timing diagram that shows how different processes and threads change their states.
