Reduced-Consistency Protocols

When the minipages defined for a certain application are larger than the sharing unit, i.e., the chunking level is set higher than one (see Section 4.4), performance may benefit from employing reduced-consistency protocols such as Lazy Release Consistency [12,26]. Thus, chunking reduces the overhead involved in fine-grain operation, while false-sharing is eliminated through the reduced consistency protocol. The overhead involved in the reduced consistency protocol itself is small compared to that measured in traditional page-based systems, due to the smaller page size.
