Abstract: A capability is provided for reallocating, to a first borrower that is requesting resources, resources presently allocated to a second borrower. A method for allocating a resource of a system includes receiving a request for a system resource allocation from a first borrower, determining a request priority of the first borrower based on a present resource allocation associated with the first borrower, determining a hold priority of a second borrower based on a present resource allocation associated with the second borrower, and determining, using the first borrower request priority and the second borrower hold priority, whether to reallocate any of the second borrower resource allocation to the first borrower.

Abstract: A capability is provided for managing resources of a system. The system resources are managed using a hierarchical organization of the system resources. The resources of the system are managed using at least one hierarchical resource pool, where a hierarchical resource pool includes a master resource pool and a plurality of virtual resource pools. The master resource pool includes a logical representation of the resources managed by the hierarchical resource pool. The virtual resource pools include logical representations of respective subsets of the resources managed by the hierarchical resource pool. A method for managing resources of a management system includes receiving, from a borrower, a resource request for one of a plurality of resources of the management system where the resources are managed using a hierarchal resource pool, identifying a virtual resource pool associated with the resource request, and determining whether to serve the resource request from the identified virtual resource pool.
