Ensuring affinity at all affinity domains by folding at each affinity level possible for a partition spanning multiple nodes

The different illustrative embodiments provide a method, apparatus, and computer program product for folding at each affinity level for a partition spanning multiple nodes. In one illustrative embodiment, a method is provided for identifying a number of domains in a number of affinity levels. A lightest loaded domain is identified in the number of domains identified. A number of nodes are identified in the lightest loaded domain identified. A lightest loaded node is identified in the number of nodes. A lightest loaded processing unit on the lightest loaded node is identified and the lightest loaded processing unit is folded.
