Regard as a computer system that runs 5000 jobs per month with no deadlock-prevention or deadlock-avoidance scheme. Deadlocks take place about twice per month and the operator must terminate and rerun about jobs per deadlock. Every job is worth about $2 (in CPU time) and the jobs terminated tend to be about half-done when they are aborted.
A systems programmer has approximated that a deadlock-avoidance algorithm like the banker's algorithm could be installed in the system with a raise in the average execution time per job of about 10 percent. Because the machine currently has 30-percent idle time all 5000 jobs per month could still run although turnaround time would increase by about 20 percent on average.
a. What are the arguments meant for installing the deadlock-avoidance algorithm?
b. What are the arguments alongside installing the deadlock-avoidance algorithm?
Answer: An argument for installing deadlock forestalling in the system is that we could ensure deadlockwould never occurs. Additionally despite the increase in turnaround time all 5000 jobs could still run. An argument alongside installing deadlock avoidance software is that deadlocks take place infrequently and they cost little when they do occur.
