Robust Collaborative Learning with Linear Gradient Overhead

Rachid Guerraoui, John Stephan, Sadegh Farhadkhani, Le Nguyen Hoang, Nirupam Gupta, Rafaël Benjamin Pinot

Collaborative learning algorithms, such as distributed SGD (or D-SGD), are prone to faulty machines that may deviate from their prescribed algorithm because of software or hardware bugs, poisoned data or malicious behaviors. While many solutions have been ...

Machines for Materials and Materials for Machines: Metal-Insulator Transitions and Artificial Intelligence

Bernat Mundet

In this perspective, we discuss the current and future impact of artificial intelligence and machine learning for the purposes of better understanding phase transitions, particularly in correlated electron materials. We take as a model system the rare-eart ...

Placement of Virtual Containers on NUMA systems: A Practical and Comprehensive Model

Baptiste Joseph Eustache Lepers

Our work addresses the problem of placement of threads, or virtual cores, onto physical cores in a multicore NUMA system. Different placements result in varying degrees of contention for shared resources, so choosing the right placement can have a large ef ...

High Frequency Effects of Impedances and Coatings in the CLIC Damping Rings

Eirini Koukovini Platia

The Compact Linear Collider (CLIC) is a 3 TeV e+e- machine, currently under design at CERN, that targets to explore the terascale particle physics regime. The experiment requires a high luminosity of 2x10^34 cm^2 s^-1, which can be achieved with ultra low ...

Insights into the thermo-mechanics of orthogonal nanometric machining

Jean-François Molinari, Guillaume Anciaux, Pedro Romero

The fabrication of high precision miniaturized components in micro- and nano-technologies requires a deep understanding of the physical mechanisms governing the nanomachining process. To aid with this need, the current article employs molecular dynamics to ...

TBM tunneling in marble rock masses with high in situ stress and large groundwater inflow: a case study in China

Lijun Yin

Two of four headrace tunnels in the Jinping II hydropower project were constructed using tunnel boring machines (TMBs). The geology along the tunnel alignment is dominantly massive to highly fractured marble and the maximum overburden depth is 2,525 m. The ...

State Machine Replication : from Analytical Evaluation to High-Performance Paxos

Nuno Filipe de Sousa Santos

Since their invention more than half a century ago, computers have gone from being just an handful of expensive machines each filling an entire room, to being an integral part of almost every aspect of modern life. Nowadays computers are everywhere: in our ...

Tight Approximation Algorithms for Scheduling with Fixed Jobs and Nonavailability

Ola Nils Anders Svensson, Klaus Jansen

We study two closely related problems in nonpreemptive scheduling of jobs on identical parallel machines. In these two settings there are either fixed jobs or nonavailability intervals during which the machines are not available; in both cases, the objecti ...

Friction at the tool-chip interface during orthogonal nanometric machining

Jean-François Molinari, Guillaume Anciaux, Pedro Romero

Understanding the unfolding of friction between the tool and the generated chip is of fundamental importance to nanometric machining processes. To this end, this paper investigates the influence of tool geometry, lattice orientation, machining velocity and ...
