Abstract
A facility for determining whether to consistency-check a cache entry is described. The facility randomly or pseudorandomly selects a value in a range. If the selected value satisfies a predetermined consistency-checking threshold within the range, the facility consistency-checks the entry, and may decide to propagate this knowledge to other cache managers. If, on the other hand, the selected value does not satisfy the consistency-checking threshold, the facility determines not to consistency-check the entry.
