SWARM: Replicating Shared Disaggregated-Memory Data in No Time

Rachid Guerraoui, Antoine Murat, Mihail Igor Zablotchi, Athanasios Xygkis

Memory disaggregation is an emerging data center architecture that improves resource utilization and scalability. Replication is key to ensure the fault tolerance of applications, but replicating shared data in disaggregated memory is hard. We propose SWAR ...

DSig: Breaking the Barrier of Signatures in Data Centers

Rachid Guerraoui, Antoine Murat, Mihail Igor Zablotchi, Athanasios Xygkis

Data centers increasingly host mutually distrustful users on shared infrastructure. A powerful tool to safeguard such users are digital signatures. Digital signatures have revolutionized Internet-scale applications, but current signatures are too slow for ...

uKharon: A Membership Service for Microsecond Applications

Rachid Guerraoui, Antoine Murat, Javier Picorel Obando, Athanasios Xygkis

Modern data center fabrics open the possibility of microsecond distributed applications, such as data stores and message queues. A challenging aspect of their development is to ensure that, besides being fast in the common case, these applications react fa ...

uBFT: Microsecond-Scale BFT using Disaggregated Memory

Rachid Guerraoui, Antoine Murat, Mihail Igor Zablotchi, Athanasios Xygkis, Naama Ben David

We propose uBFT, the first State Machine Replication (SMR) system to achieve microsecond-scale latency in data centers, while using only 2f+1 replicas to tolerate f Byzantine failures. The Byzantine Fault Tolerance (BFT) provided by uBFT is essential as pu ...
