Chip-Level Redundancy in Distributed Shared-Memory Multiprocessors

Distributed shared-memory (DSM) multi- processors provide a scalable hardware platform, but lack the necessary redundancy for mainframe-level reliability and availability. Chip-level redundancy in a DSM server faces a key challenge: the increased latency t ...

Design and development of the point-ahead angle mechanism for the lase interferometer space antenna (LISA)

Simon Nessim Henein, Philippe Schwab

The Point Ahead Angle Mechanism (PAAM) for ESA’s Laser Interferometer Space Antenna (LISA) mission will compensate the out-of-plane point-ahead angle between three satellites flying 5 million kilometres apart. The PAAM consists of a mirror supported by fle ...

Case Study of Fault-Tolerant Architectures for 90nm CMOS Cryptographic Cores

Alexandre Schmid, Yusuf Leblebici, Milos Stanisavljevic, Maria Gabrani

This paper presents a case study of different fault-tolerant architectures. The emphasis is on the silicon realization. A 128bit AES cryptographic core has been designed and fabricated as a main topology on which the fault-tolerant architectures have been ...

Primal-Dual Enumeration for Multiparametric Linear Programming

Colin Neil Jones

Optimal control problems for constrained linear systems with a linear cost can be posed as multiparametric linear programs (pLPs) and solved explicitly offline. Several algorithms have recently been proposed in the literature that solve these pLPs in a fai ...

Autonomous Recovery in Componentized Internet Applications

George Candea

In this paper we show how to reduce downtime of J2EE applications by rapidly and automatically recovering from transient and intermittent software failures, without requiring application modifications. Our prototype combines three application-agnostic tech ...

System ductility and redundancy of FRP beam structures with ductile adhesive joints

Thomas Keller, Julia De Castro San Roman Fest

This paper reports on a structural concept for engineering structures composed of FRP components to provide system ductility that compensates for the lack of material ductility inherent to FRP materials. The concept includes the use of redundant structural ...

Understanding the performance of concurrent error detecting superscalar microarchitectures

Babak Falsafi

Superscalar out-of-order microarchitectures can be modified to support redundant execution of a program as two concurrent threads for soft-error detection. However, the extra workload from redundant execution incurs a performance penalty due to increased c ...

Early developmental arrest of mammalian limbs lacking HoxA/HoxD gene function

Denis Duboule, Jozsef Zakany

Vertebrate HoxA and HoxD cluster genes are required for proper limb development. However, early lethality, compensation and redundancy have made a full assessment of their function difficult. Here we describe mice that are lacking all Hoxa and Hoxd functio ...

Efficient resource sharing in concurrent error detecting superscalar microarchitectures

Babak Falsafi

Previous proposals for soft-error tolerance have called for redundantly executing a program as two concurrent threads on a superscalar microarchitecture. In a balanced superscalar design, the extra workload from redundant execution induces a severe perform ...

Measurement of quartz particles by means of an atomic force microscope for planetary exploration

Nico de Rooij, Terunobu Akiyama, Sebastian Gautsch

Within the last 2 years our consortium has developed, built and tested an atomic force microscope for planetary science applications, in particular for the study of Martian dust and soil. An array of eight cantilevers and tips provides redundancy in case o ...
