PAI: A lightweight mechanism for single-node memory recovery in DSM servers

Babak Falsafi

Several recent studies identify the memory system as the most frequent source of hardware failures in commercial servers. Techniques to protect the memory system from failures must continue to service memory requests, despite hardware failures. Furthermore ...

Mirroring Resources or Mapping Requests: Implementing WS-RF for Grid Workflows

Thomas Heinis

The Web services resource framework (WS-RF) and the Web services notification (WS-N) specifications are a crucial component of grid infrastructures. They provide a standardized interface to stateful services so that they can be managed remotely. There are ...

Service Interface: A New Abstraction for Implementing and Composing Protocols

André Schiper, Olivier Rütti

In this paper we compare two approaches to the design of protocol frameworks -- tools for implementing modular network protocols. The most common approach uses events as the main abstraction for a local interaction between protocol modules. We argue that a ...

Composition for component-based modeling

Joseph Sifakis

We propose a framework for component-based modeling that bring some answers to the component-based design problems. The framework uses an abstract layered model of components. It integrates and simplifies results about modeling timed systems by using timed ...
