Consider a system that has two cpus and each cpu has two threads (hyperthreading). suppose three processes, p0, pl, and p2, are started with run times of 5, 10 and 20 msec, respectively. how long will it take to complete the execution of these processes? discuss all possibilities depending on different processes scheduled to run on different cpus/threads, and what is the minimum execution time? assume that all three processes are 100% cpu bound, do not block during execution, and do not change cpus once assigned
