How to Stop Under-Utilization and Love Multicores

Anastasia Ailamaki, Pinar Tözün, Danica Porobic, Iraklis Psaroudakis, Erietta Liarou

Designing scalable transaction processing systems on modern hardware has been a challenge for almost a decade. Hardware trends oblige software to overcome three major challenges against systems scalability: (1) Exploiting the abundant thread-level parallel ...

Top-Down Fabrication of Gate-All-Around Vertically-Stacked Silicon Nanowire FETs with Controllable Polarity

Giovanni De Micheli, Davide Sacchetto, Yusuf Leblebici, Pierre-Emmanuel Julien Marc Gaillardon, Jian Zhang, Michele De Marchi

Asthe currentMOSFET scaling trend is facing strong limitations, technologies exploiting novel degrees of freedom at physical and architecture level are promising candidates to enable the continuation of Moore's predictions. In this paper, we report on the ...

Prototyping Symbolic Execution Engines for Interpreted Languages

George Candea, Johannes Kinder, Stefan Bucur

Symbolic execution is being successfully used to automatically test statically compiled code. However, increasingly more systems and applications are written in dynamic interpreted languages like Python. Building a new symbolic execution engine is a monume ...

Markov Decision Process Based Energy-Efficient Scheduling For Slice-Parallel Video Decoding

David Atienza Alonso, Karim Kanoun

We consider the problem of energy-efficient scheduling for slice-parallel video decoders on multicore systems with Dynamic Voltage Frequency Scaling (DVFS) enabled processors. We rigorously formulate the problem as a Markov decision process (MDP), which si ...

From A to E: Analyzing TPC’s OLTP Benchmarks -- The obsolete, the ubiquitous, the unexplored

Anastasia Ailamaki, Pinar Tözün, Ippokratis Pandis, Ilknur Cansu Kaynak, Dorde Jevdic

Introduced in 2007, TPC-E is the most recently standardized OLTP benchmark by TPC. Even though TPC-E has already been around for six years, it has not gained the popularity of its predecessor TPC-C: all the published results for TPC-E use a single database ...

Markov Decision Process Based Energy-Efficient On-Line Scheduling for Slice Parallel Video Decoders on Multicore Systems

Pascal Frossard, David Atienza Alonso, Karim Kanoun

We consider the problem of energy-efficient on-line scheduling for slice-parallel video decoders on multicore systems. We assume that each of the processors are Dynamic Voltage Frequency Scaling (DVFS) enabled such that they can independently trade off per ...

Achieving high-throughput State Machine Replication in multi-core systems

André Schiper, Nuno Filipe de Sousa Santos

The traditional architecture used by implementations of Replicated State Machines (RSM) does not fully exploit modern multi-core CPUs. This is increasingly the limiting factor in their performance, because network speeds are increasing much faster than the ...

Instruction Set Extensions for Cryptographic Hash Functions on a Microcontroller Architecture

Andreas Peter Burg, Jeremy Hugues-Felix Constantin

In this paper, we investigate the benefits of instruction set extensions (ISEs) on a 16-bit microcontroller architecture for software implementations of cryptographic hash functions, using the example of the five SHA-3 final round candidates. We identify t ...

Optically-Clocked Instruction Set Extensions for High Efficiency Embedded Processors

Edoardo Charbon, Ties Jan Henderikus Kluter, Claudio Favi, Christian Mester

We propose a technique to localize computation in Instruction Set Extensions (ISEs) that are clocked at very high speed with respect to the processor. In order to save power, data to and from Custom Instruction Units (CIUs) is synchronized via an optical s ...

Polarity Control in Double-Gate, Gate-All-Around Vertically Stacked Silicon Nanowire FETs

Giovanni De Micheli, Davide Sacchetto, Yusuf Leblebici, Pierre-Emmanuel Julien Marc Gaillardon, Jian Zhang, Michele De Marchi

We fabricated and characterized ambipolar Silicon Nanowire (SiNW) FET transistors featuring two independent Gate-All-Around (GAA) electrodes and vertically stacked SiNW channels. One of the gate electrodes is exploited to dynamically select the polarity of ...
