Palestra Prof. Fernando Pedone

O Prof. Pedone da universidade de Lugano, Suiça que está nos visitando vai fazer uma palestra (talk de uma hora + tempo para perguntas) na sala da PG da Automação as 16 horas nesta quinta-feira 27/11/14. O titulo e o resumo da apresentacao estão abaixo.

Title: Scalable State-Machine Replication

Abstract:

State-machine replication (SMR) is a well-known fault-tolerance technique. SMR consists of sequencing client requests and executing them against replicas in the same order; thanks to deterministic execution, every replica reaches the same state after executing the same sequence of requests. Despite its simple execution model, SMR does not scale performance: since every replica added to the system needs to execute all requests, throughput does not improve with the number of replicas.

In this talk, I will present Scalable SMR (S-SMR), a technique that extends state-machine replication to scale (a) with the number of replicas (scale out) and (b) with the number of processors in a replica (scale up). I will also describe Eyrie, a library in Java that implements S-SMR, and Volery, an application that implements Zookeeper’s API. We assessed the performance of Volery and compared the results to Zookeeper.
