Rebooting Virtual Memory with Midgard

Virtual Memory (VM) is a critical programming abstraction that is widely used in various modern computing platforms. With the rise of datacenter computing and birth of planet-scale online services, the semantic and capacity requirements from memory have ev ...

Nonlinear Inverse Problems in Quantitative Phase Imaging

Thanh-An Michel Pham

The topic of this thesis is the development of new algorithmic reconstruction methods for quantitative phase imaging (QPI). In the past decade, advanced QPI has emerged as a valuable tool to study label-free biological samples and uncover their 3D structur ...

SMoTherSpectre: Exploiting Speculative Execution through Port Contention

Babak Falsafi, Mathias Josef Payer, Atri Bhattacharyya

Spectre, Meltdown, and related attacks have demonstrated that kernels, hypervisors, trusted execution environments, and browsers are prone to information disclosure through micro-architectural weaknesses. However, it remains unclear as to what extent other ...

A Power-Efficient 3-D On-Chip Interconnect for Multi-Core Accelerators with Stacked L2 Cache

Giovanni De Micheli, Luca Benini

The use of multi-core clusters is a promising option for data-intensive embedded applications such as multi-modal sensor fusion, image understanding, mobile augmented reality. In this paper, we propose a power-efficient 3-D on-chip interconnect for multi-c ...

Exploiting Dynamic Timing Margins in Microprocessors for Frequency-Over-Scaling with Instruction-Based Clock Adjustment

Andreas Peter Burg, Georgios Karakonstantis, Jeremy Hugues-Felix Constantin, Anupam Chattopadhyay

Static timing analysis provides the basis for setting the clock period of a microprocessor core, based on its worst-case critical path. However, depending on the design, this critical path is not always excited and therefore dynamic timing margins exist th ...

On the Performance of Delegation over Cache-Coherent Shared Memory

André Schiper, Thomas Ropars, Darko Petrovic

Delegation is a thread synchronization technique where access to shared data is performed through a dedicated server thread. When a client thread requires shared data access, it makes a request to a server and waits for a response. This paper studies deleg ...

FADE: A Programmable Filtering Accelerator for Instruction-Grain Monitoring

Babak Falsafi, Boris Robert Grot, Yusuf Onur Koçberber, Sotiria Fytraki, Evangelos Vlachos

Instruction-grain monitoring is a powerful approach that enables a wide spectrum of bug-finding tools. As existing software approaches incur prohibitive runtime overhead, researchers have focused on hardware support for instruction-grain monitoring. A recu ...

Quantifying the Mismatch between Emerging Scale-Out Applications and Modern Processors

Anastasia Ailamaki, Babak Falsafi, Michael Ferdman, Mohammad Alisafaee, Yusuf Onur Koçberber, Stavros Volos, Ilknur Cansu Kaynak, Adrian Daniel Popescu, Al Mutaz Adileh, Dorde Jevdic

Emerging scale-out workloads require extensive amounts of computational resources. However, data centers using modern server hardware face physical constraints in space and power, limiting further expansion and calling for improvements in the computational ...

How TMS and stimulus off/on signals modulate feature integration

Michael Herzog, Frank Scharnowski, Johannes Rüter

When a right offset vernier is immediately followed by a left offset vernier (or vice versa), only one vernier is perceived. Feature fusion has occurred. In feature fusion, observers cannot resolve the two verniers individually. Subjects perform at chance ...
