摘要: A dirty memory for a computer system is configured hierarchically. This provides more rapid identification of pages that have been dirtied and require attention. For example the reintegration an equivalent state to memories respective processing sets in fault tolerant following lockstep error. The includes at least two levels. lower level groups indicators, each indicator being settable given indicative page associated therewith has dirtied. At one higher group indicators predetermined There can be layers. Logic controls operation hierarchical memory.
