Efficient Multi-Word Compare and Swap

Rachid Guerraoui, Mihail Igor Zablotchi

Atomic lock-free multi-word compare-and-swap (MCAS) is a powerful tool for designing concurrent algorithms. Yet, its widespread usage has been limited because lock-free implementations of MCAS make heavy use of expensive compare-and-swap (CAS) instructions ...

Synthesis of Flexible Accelerators for Early Adoption of Ring-LWE Post-quantum Cryptography

Francesco Regazzoni, Subhadeep Banik, Hamid Nejatollahi

The advent of the quantum computer makes current public-key infrastructure insecure. Cryptography community is addressing this problem by designing, efficiently implementing, and evaluating novel public-key algorithms capable of withstanding quantum comput ...

A Rule Synthesis Algorithm for Programmable Stochastic Self-Assembly of Robotic Modules

Alcherio Martinoli, Bahar Haghighat

Programmable self-assembly of modular robots offers promising means for structure formation at different scales. Rule-based approaches have been previously employed for distributed control of stochastic self-assembly processes. The assembly rate in the pro ...

SoK: Shining Light on Shadow Stacks

Mathias Josef Payer, Xiangyu Zhang

Control-Flow Hijacking attacks are the dominant attack vector against C/C++ programs. Control-Flow Integrity (CFI) solutions mitigate these attacks on the forward edge, i.e., indirect calls through function pointers and virtual calls. Protecting the backwa ...

Dynamically resolved self-assembly of S-layer proteins on solid surfaces

Magalí Alejandra Lingenfelder, Bart Willem Stel, Fernando Pablo Cometto

By using high-speed and high-resolution Atomic Force Microscopy (AFM), it was possible to resolve within a single experiment the kinetic pathway in S-layer self-assembly at the solid-liquid interface, obtaining a model that accounts for the nucleation, gro ...

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 ...

Online Updates on Data Warehouses via Judicious Use of Solid-State Storage

Anastasia Ailamaki, Manoussos Gavriil Athanassoulis, Radu Ioan Stoica

Data warehouses have been traditionally optimized for read-only query performance, allowing only offline updates at night, essentially trading off data freshness for performance. The need for 24x7 operations in global markets and the rise of online and oth ...

A cohesive element model for mixed mode loading with frictional contact capability

Jean-François Molinari, Leonardo Snozzi

We present a model that combines interface debonding and frictional contact. The onset of fracture is explicitly modeled using the well-known cohesive approach. Whereas the debonding process is controlled by a new extrinsic traction separation law, which a ...
