Question
5.Processes p1 and p2 execute on a system with a single CPU and 2 identical I/O devices. The compute-bound phase of each process is 800
5.Processes p1 and p2 execute on a system with a single CPU and 2 identical I/O devices. The compute-bound phase of each process is 800 time units, followed by an I/O-bound phase of 400 time units. The processes run concurrently using time-sharing. Assume that the switching overhead and the switching periods are negligible.
a.If both I/O devices are used, what is the total execution time for both processes
? b.If only one I/O device is used, what is the total execution time for both processes?
