Alea-BFT: Practical Asynchronous Byzantine Fault Tolerance
Diogo S. Antunes, Afonso N. Oliveira, André Breda +3
Traditional Byzantine Fault Tolerance (BFT) state machine replication protocols assume a partial synchrony model, leading to a design where a leader replica drives the protocol and…
Alea-BFT: Practical Asynchronous Byzantine Fault Tolerance
Afonso Oliveira, Henrique Moniz, Rodrigo Rodrigues
Traditional Byzantine Fault Tolerance (BFT) state machine replication protocols assume a partial synchrony model, leading to a design where a leader replica drives the protocol and…
With Great Freedom Comes Great Opportunity: Rethinking Resource Allocation for Serverless Functions
Muhammad Bilal, Marco Canini, Rodrigo Fonseca +1
Current serverless offerings give users a limited degree of flexibility for configuring the resources allocated to their function invocations by either coupling memory and CPU reso…
Lazy State Determination: More concurrency for contending linearizable transactions
Tiago M. Vale, João Leitão, Nuno Preguiça +3
The concurrency control algorithms in transactional systems limits concurrency to provide strong semantics, which leads to poor performance under high contention. As a consequence,…
Aion: Better Late than Never in Event-Time Streams
Sérgio Esteves, Gianmarco De Francisci Morales, Rodrigo Rodrigues +2
Processing data streams in near real-time is an increasingly important task. In the case of event-timestamped data, the stream processing system must promptly handle late events th…
Bandwidth-Aware Page Placement in NUMA
David Gureya, João Neto, Reza Karimi +6
Page placement is a critical problem for memoryintensive applications running on a shared-memory multiprocessor with a non-uniform memory access (NUMA) architecture. State-of-the-a…
IPA: Invariant-preserving Applications for Weakly-consistent Replicated Databases
Valter Balegas, Nuno Preguiça, Sérgio Duarte +2
Storage systems based on Weak Consistency provide better availability and lower latency than systems that use Strong Consistency, especially in geo-replicated settings. However, un…
Generalized Paxos Made Byzantine (and Less Complex)
Miguel Pires, Srivatsan Ravi, Rodrigo Rodrigues
One of the most recent members of the Paxos family of protocols is Generalized Paxos. This variant of Paxos has the characteristic that it departs from the original specification o…
Making data center computations fast, but not so furious
Daniel Porto, João Loff, Rui Duarte +2
We propose an aggressive computational sprinting variant for data center environments. While most of previous work on computational sprinting focuses on maximizing the sprinting pr…
Extending Eventually Consistent Cloud Databases for Enforcing Numeric Invariants
Valter Balegas, Diogo Serra, Sérgio Duarte +5
Geo-replicated databases often operate under the principle of eventual consistency to offer high-availability with low latency on a simple key/value store abstraction. Recently, so…
