8. A biprocessor system is described using the M/M/2 model. The average processor service time is 20 msec and the processor utilization is 40%. (a) (b) Compute the average response time. Compute the processor utilization and the average response time in the case where one processor is down. 8. A biprocessor system is described using the M/M/2 model.
