Question

Suppose that we have amultiprogrammed computer (see figure 2.5 for example). In thissimulation, each job has identical characteristics. In onecomputation period, T, for a job, half the time is spent in I/O andthe other half in processor activity. Each job runs for atotal of N periods. Assume that a simple round-robinscheduling is used, and that I/O operations can overlap withprocessor operation. We will define the following quantitiesthat you need to calculate:

·        Turnaroundtime = actual time to complete a job

·        Throughput =average number of jobs completed per time period T

·        Processorutilization = percentage of time that the processor is active (notwaiting)

Compute these 3 definedquantities for one, two, and four simultaneous jobs, assuming thatthe period T is distributed in each of the followingways:

a)      I/O first half, processorsecond half

b)      I/O first and third quarters,processor second and fourth quarters
