Consensus in the presence of mortal Byzantine faulty processes

We consider the problem of reaching agreement in distributed systems in which some processes may deviate from their prescribed behavior before they eventually crash. We call this failure model "mortal Byzantine". After discussing some application examples ...

Of Choices, Failures and Asynchrony: The Many Faces of Set Agreement

Rachid Guerraoui, Seth Gilbert, Dan Alistarh

Set agreement is a fundamental problem in distributed computing in which processes collectively choose a small subset of values from a larger set of proposals. The impossibility of fault-tolerant set agreement in asynchronous networks is one of the seminal ...

A Current Sensing Completion Detection Method for Asynchronous Pipelines Operating In the Sub-threshold Regime

Yusuf Leblebici, Omer Can Akgun

Digital circuits operating in the sub-threshold regime are able to perform minimum energy operation at a given delay. In the sub-threshold regime the circuit delay, and hence, the leakage energy consumption depend on the supply voltage exponentially. By re ...

Energy efficiency enhancement of sub-threshold digital CMOS : modeling, technology selection and architectural exploration

Omer Can Akgun

Power density and energy dissipation of digital IC's has become one of the main concerns during the recent years. With the increased usage of battery powered devices, ubiquitous computing, and increase in implantable biomedical applications, enhancing ener ...

Energy Efficiency Comparison of Asynchronous and Synchronous Circuits Operating in the Sub-Threshold Regime

Yusuf Leblebici, Omer Can Akgun

Digital circuits operating in the sub-threshold regime are able to perform minimum energy operation at a given delay. In the sub-threshold regime circuit delay, hence the leakage energy consumption depends on the supply voltage exponentially. By reducing t ...
