A system and method for managing resources in a partitioned computing system using determined risk of resource saturation is disclosed. In one example embodiment, the partitioned computing system includes one or more partitions. A volatility of resource usage for each partition is computed based on computed resource usage gains/losses associated with each partition. A current resource usage of each partition is then determined. Further, a risk of resource saturation is determined by comparing the computed volatility of resource usage with the determined current resource usage of each partition. The resources in the partitioned computing system are then managed using the determined risk of resource saturation associated with each partition.
