Linebacker: Preserving Victim Cache Lines in Idle Register Files of GPUs

Modern GPUs suffer from cache contention due to the limited cache size that is shared across tens of concurrently running warps. To increase the per-warp cache size prior techniques proposed warp throttling which limits the number of active warps. Warp thr ...

Asynchronous Branch-Paralle Simulation of Detailed Neuron Models

Michael Lee Hines

Simulations of electrical activity of networks of morphologically detailed neuron models allow for a better understanding of the brain. State-of-the-art simulations describe the dynamics of ionic currents and biochemical processes within branching topologi ...

A Brain-Controlled Exoskeleton with Cascaded Event-Related Desynchronization Classifiers

José del Rocio Millán Ruiz, Kyuhwa Lee, Ricardo Andres Chavarriaga Lozano, Dong Liu

This paper describes a brain-machine interface for the online control of a powered lower-limb exoskeleton based on electroencephalogram (EEG) signals recorded over the user’s sensorimotor cortical areas. We train a binary decoder that can distinguish two d ...

When Constant-time Source Yields Variable-time Binary: Exploiting Curve25519-donna Built with MSVC 2015

Serge Vaudenay

The elliptic curve Curve25519 has been presented as pro- tected against state-of-the-art timing attacks [2]. This paper shows that a timing attack is still achievable against a particular X25519 implemen- tation which follows the RFC 7748 requirements [11] ...

Hierarchical Cycle Accounting: A New Method for Application Performance Tuning

Willy Zwaenepoel, Andrzej Pawel Nowak

To address the growing difficulty of performance debugging on modern processors with increasingly complex micro-architectures, we present Hierarchical Cycle Accounting (HCA), a structured, hierarchical, architecture-agnostic methodology for the identificat ...

Restructuring of Arithmetic Circuits with Biconditional Binary Decision Diagrams

Giovanni De Micheli, Andreas Peter Burg, Alexios Konstantinos Balatsoukas Stimming, Pierre-Emmanuel Julien Marc Gaillardon, Luca Gaetano Amarù

Biconditional Binary Decision Diagrams (BBDDs) are a novel class of canonical binary decision diagrams where the branching condition, and its associated logic expansion is biconditional on two variables. In this demonstration we use an effici ...

Biconditional Binary Decision Diagrams: A Novel Canonical Logic Representation Form

Giovanni De Micheli, Pierre-Emmanuel Julien Marc Gaillardon, Luca Gaetano Amarù

In this paper, we present biconditional binary deci- sion diagrams (BBDDs), a novel canonical representation form for Boolean functions. BBDDs are binary decision diagrams where the branching condition, and its associated logic expansion, is biconditional ...
