ABSTRACT:
Managing physical memory for one or more processes with both a minimum and a maximum amount of physical memory. Memory sets are created, each specifying a number of credits. The total number of credits specified by all memory sets are equal to the total number of pages in physical memory. One or more processes are bound to a memory set. All of the processes bound to a memory set are collectively referred to as the workload of the memory set. Each physical page is accounted for to ensure that each workload can utilize at least the number of physical pages equaling the number of credits in its memory set. Additionally, a workload is permitted to use physical pages that are being explicitly shared by workloads of other memory sets. Accordingly, a workload with both a minimum and a maximum amount of physical memory is specified by its memory set.
