A multiprocessor with 10 processors has 36 attached tape drives. A number of jobs have been submitted to the system where each job requires a maximum of 6 drives in order to complete execution. Assume that each job starts running with only 4 drives for a long period before requiring the other 2 drives for a short period toward the end of its operation. Also assume an endless supply of those jobs. Assume the scheduler in the operating system will not start a job unless there are 6 tape drives available. When a job is started, 6 drives are assigned immediately and are not released until the job finishes. 5.1 What is the maximum number of jobs that can be in progress at once? 5.2 What is the maximum number of tape drives that may be left idle as a result of this policy? 5.3 What is the minimum number of tape drives that may be left idle as a result of this policy?
