DDSS: A Low-Overhead Distributed Data Sharing Substrate for Cluster-Based Data-Centers Over Modern Interconnects

Information-sharing is a key aspect of distributed applications such as database servers and web servers. Information-sharing also assists services such as caching, reconfiguration, etc. In the past, information-sharing has been implemented using ad-hoc messaging protocols which often incur high overheads and are not very scalable. This paper presents a new design for a scalable and a low-overhead Distributed Data Sharing Substrate (DDSS). DDSS is designed to support efficient data management and coherence models by leveraging the features of modern interconnect.
