of Customer1’s processes receive 25% of the resource. This scenario assumes that the three processes fully consume the resource allocated to their groups.

Prioritizing resource use between users

Figure 3 illustrates how users’ access to resources can be prioritized using PRM. In this example, two university departments both contributed to the purchase of a new computer. The math department paid 25% of the cost, and the engineering department paid 75%. PRM groups are assigned accordingly: 25% for the math PRM group MGroup and 75% for the engineering PRM group EGroup. This implies that EGroup processes have priority over MGroup processes. Each group has only one user: User1 is in MGroup; User2 is in EGroup. User1 is entitled to 25% of the available resource, and User2 is entitled to 75%. This scenario assumes that the three processes fully consume the resource allocated to their groups.

Prioritizing resource use for applications

Figure 4 illustrates a situation where two users and an application are assigned to separate PRM groups. User1 and User2 are respectively assigned to GroupA and GroupB. Both groups are given 25%. The critical application is assigned to GroupC, which is given 50%. Because of its greater resource allocation, GroupC takes priority over GroupA and GroupB. This scenario assumes that the processes fully consume the resource allocated to their groups.
