There are a large number of single threaded jobs submitted into this system that each require the use of a maximum of four SSD drives to complete their execution. Assume each job starts running with only three SSD drives for a long period of time before requiring the fourth SSD drive for a short period near the end of its execution. Also assume that there is an endless/infinite supply of these jobs. Using this system, answer the following questions: 1) Assume the scheduler in the OS will not start a job unless there are four SSD drives available. When a job is started, four drives are assigned immediately and are not released until the job finishes. a. (2 pt) What is the maximum number of jobs that can be in progress at once? b. (2 pt) What are the minimum and maximum number of CPU cores that may be left idle because of this policy? c. (2 pt) What are the minimum and maximum number of SSD drives that may be left idle because of this policy? 2) Suggest an alternative policy to improve SSD drive utilization and at the same time avoid system deadlock (where all processes can be deprived of required resources). a. (10 pts) Write out your proposed policy. b. (2 pt) What is the maximum number of jobs that can be in progress at once? c. (2 pt) What are the minimum and maximum number of CPU cores that may be left idle because of this policy? d. (2pt) What are the minimum and maximum number of SSD drives that may be left idle because of this policy
