Method and apparatus for allocating processing resources

摘要

First and second pools of resource units are configured using a structure having plural levels including first and second level resource units. A relationship is established between ones of the two pools of resource units. A request is made for a resource that requires a resource unit from both of the first and second resource unit pools. A single allocation procedure is employed to allocate resource units from both pools. If one of the resource units is available in one pool, the relationship ensures that a required corresponding resource unit in another pool is also available.
