ABSTRACT:
Units of a resource are allocated among a plurality of clients by a system-level management module using a proportional share resource allocation scheme. For each client, a metric is evaluated that is a function both of a non-usage-based, client-specific factor and of a usage-based factor. The usage-based factor is in turn a function of, as separate variables, a first and a second measure of resource units currently allocated to the respective client that the client is actively using and that are idle, respectively. At least one resource unit is then reclaimed for reallocation from the client whose metric meets a predetermined criterion. Examples of the resource include system memory, processors in a multi-processor system, I/O bandwidth, etc. Examples of clients include processes, virtual machines, remote systems connected to the management module via a network, which may be in a server, etc.
