Understanding Replication in Databases and Distributed Systems

André Schiper, Matthias Wiesmann, Fernando Pedone

Replication is an area of interest to both distributed systems and databases. The solutions developed from these two perspectives are conceptually similar but differ in many aspects: model, assumptions, mechanisms, guarantees provided, and implementation. ...

Quantifying the Performance Differences Between PVM and TreadMarks

Willy Zwaenepoel, Sandhya Dwarkadas

We compare two systems for parallel programming on networks of workstations: Parallel Virtual Machine (PVM) a message passing system, and TreadMarks, a software distributed shared memory (DSM) system. We present results for eight applications that were imp ...
