Balancing resource use between users
Figure 1-2 shows how PRM can alter standard resource allocation and
balance system resource use.
In the following scenario, a service provider wants each customer to have
an equal share of the machine. Each customer is assigned to a separate
PRM group, which is given resource shares equivalent to 50%. The
resource being allocated could be either CPU, disk bandwidth, or
memory. This configuration guarantees each PRM group 50% of the
resource for any given interval. Thus, Customer2’s process receives 50%
of the resource; however, because Customer1’s group contains two
processes, each of Customer1’s processes receive 25% of the resource.
This scenario assumes that the three processes fully consume the
resource allocated to their groups.
