Efficient, Scalable, and Fair Locking on Disaggregated Memory with Decentralized Coordination
Summary: DecLock separates lock-state maintenance on memory nodes from ownership transfer across compute nodes, using queued waiters and direct CN notifications to avoid NIC-heavy retries. It delivers scalable, fair locking under contention, improving throughput by up to 43.37× over RDMA-based locks. (summarized by gpt-5.6-luna on Aug 17 2026)
