Abstract:
A method for managing the memory of a computer system including storage devices, computer processor power, and a plurality of partitions, wherein the memory, storage devices, and computer processor power of the computer system are distributively assigned among the plurality of partitions, and wherein the computer system uses the storage devices assigned to each partition to supplement the memory assigned to the respective partition, the method comprising, for each of two or more partitions of the plurality of partitions:providing a first measurement related to the frequency with which storage devices assigned to the respective partition are used to supplement memory in the respective partition; providing a second measurement related to the efficiency with which the storage devices assigned to the respective partition supplement memory in the respective partition; providing a third measurement related to the rate at which the computer processor power assigned to the respective partition is used; calculating a memory pain value representing the degree to which computing performance in the respective partition is being degraded due to a lack of memory, the memory pain value being directly related to the first measurement and indirectly related to the second and third measurements; and storing the first value.
