A multiprocessor with 10 processors has 36 attached tape drives. A number of jobs have been submitted to the system where each j

ob 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.
1 What is the maximum number of jobs that can be in progress at once?
2 What is the maximum number of tape drives that may be left idle as a result of
this policy?
3 What is the minimum number of tape drives that may be left idle as a result of
this policy?

The maximum number of tape drivers that are required by each job in the multiprocessor is 6.

<h3>How to illustrate the information?</h3>

It is given that a job will be performed in parallel with 4 tape drivers and laterin series with remaining 2 tape drivers. The maximum number of jobs that cab be progress simultaneously will be:

= total number of tape drivers / number of tape drivers assigned for each job.

Maximum number of jobs that cab be progress simultaneously = 36 / 6 = 6

Each process run with 4 tape drivers parallel and remaining 2 tape drivers is used at the last. Therefore, most of the time the 4 tape drivers are used and the remaining 2 tape drivers is left idle.

The maximum number of tape drivers kept idle = last tape drive in each of the processes running.

There are 6 processes running so, the maximum number of processes left idle is 6.

When each process makes use of all the tape drivers, and then there will not be any idle state for the tape drivers. Therefore, the minimum number of tape drivers kept idle is 0.

Why is it necessary to understand conflict of interest and how it could affect you at work​
Anastasy [175]

Answer:

Conflict of interest is a common issue in the workplace. Most of us have heard someone say, “It’s who you know, not what you know.” We have heard co-workers complain that a manager’s relative always gets the biggest raise or the best assignment. We might have seen colleagues accept gifts from potential vendors. Maybe a co-worker leaves work 20 minutes early every day so she can get to her second job. A supervisor may give a co-worker time off from work to do volunteer work or might allow employees to solicit donations and funds in the workplace, whether for the Girl Scouts or a local school function. Even though these situations are very different, they all fall under the heading of “conflict of interest.”

Explanation:are a clash that most often occurs between requirements and interests. Various types of conflicts of interest can occur because of the nature of relationships versus rules of organizations or federal and state laws. People can easily become biased (have an unfair preference) because of small things like friendship, food, or flattery, or they may be influenced to make a decision because of the potential to gain power, prestige, or money. Conflicts can occur when an individual makes or influences a decision and does so for some personal gain that may be unfair, unethical, or even illegal. The important part is what you do in each of those situations. Do you allow your family, friendship, financial, or inside knowledge affect your actions? If you do, you could be violating state statute and university policy.

In our work lives, we also have interests that could influence the way we do our jobs and the decisions we make. Even if we never act on them, there may be an appearance that a conflict of interest has influenced our decisions. Consider this example. Your supervisor is promoted to department director. His daughter-in-law is hired as a new supervisor within the college but is not reporting to him. Maybe the new supervisor is the best candidate for that position, and maybe the new department director had nothing to do with her hire. Even if this hire met all of the requirements under our Employment of Relatives policy, the situation appears suspicious and employees may think that something was unfair or unethical about her hire.

Transparency (being completely open and frank) becomes important when dealing with both actual and potentially perceived conflicts of interest. Perception happens when an individual observes something (behavior or activity) and comes to a conclusion. Perceiving a conflict of interest does not make it a conflict of interest. The true test of verifying whether a matter is just a potentially perceived conflict of interest, or an actual conflict of interest, is disclosure.
