Method and system for hierarchical resource management involving hard and soft resource limits

摘要

The present invention manages resources in a computing device to facilitate the allocation of resources amongst competing clients operating on the device. A hierarchy of budgets is constructed to encode restrictions on the aggregated use of a resource allocated by a resource provider to one or more clients. A resource manager validates and arbitrates requests to allocate resources to the one or more clients by resource providers in accordance with the budgets comprising the hierarchy. The resource manager notifies clients of availability and shortages of resources to promote compliance with the restrictions encoded in the budgets of the hierarchy.
