WebApr 7, 2024 · This is the first work to characterize the complexity of consistency checking for C11 memory models, in particular, the RC20 model, its release-acquire fragment, the strong and weak variants of RA (SRA and WRA), as well as the Relaxed fragment of RC20. Over the years, several memory models have been proposed to capture the subtle … Webdatabase model and define strong consistency. We describe the proposed lazy approaches to provide strong consistency in Section III. In Section IV we present the architecture and de-sign of our replicated database prototype and explain how the proposed techniques for strong consistency are implemented.
