Abstract

In this brief announcement, we define operation asymmetry, which captures how processes may interact with an object differently, and discuss its implications in the context of a popular network communication technology, remote direct memory access (RDMA). Then, we present a novel approach to mutual exclusion for RDMA-based distributed synchronization under operation asymmetry. Our approach avoids RDMA loopback for local processes and guarantees starvation-freedom and fairness.
