An OS is using round-robin CPU scheduling (time slice=3ms) on a system with 10 CPUs. A process has just arrived on the system and immediately creates 11 threads. These threads have the same service time of 21ms each, they make no I/O requests, and they will all successfully terminate. We assume: 1) the 5-state process model, 2) no other user programs are executing, 3)  thread management and OS activities consume negligible time, and 4) the process immediately terminates when all of its threads have terminated.

 What is the turnaround time (in ms) for this process if these are:

1) user-level threads (ULTs)? 

2) kernel-level threads (KLTs) that can be assigned to different CPUs in parallel?
