Dalek: An Unconventional and Energy-Aware Heterogeneous Cluster
Adrien Cassagne, Noé Amiot, Manuel Bouyer
Dalek is an experimental compute cluster designed to evaluate the performance of heterogeneous, consumer-grade hardware for software design, prototyping, and algorithm development.…
Task-based Augmented Contour Trees with Fibonacci Heaps
Charles Gueunet, P. Fortin, J Jomier +1
This paper presents a new algorithm for the fast, shared memory, multi-core computation of augmented contour trees on triangulations. In contrast to most existing parallel algorith…
Reliable Broadcast in Dynamic Networks with Locally Bounded Byzantine Failures
Silvia Bonomi, Giovanni Farina, Sébastien Tixeuil
Ensuring reliable communication despite possibly malicious participants is a primary objective in any distributed system or network. In this paper, we investigate the possibility o…
Distributed transactional reads: the strong, the quick, the fresh \& the impossible
Alejandro Z. Tomsic, Manuel Bravo, Marc Shapiro
This paper studies the costs and trade-offs of providing transactional consistent reads in a distributed storage system. We identify the following dimensions: read consistency, rea…
Correctness and Fairness of Tendermint-core Blockchains
Yackolley Amoussou-Guenou, Antonella Del Pozzo, Maria Potop-Butucaru +1
Tendermint-core blockchains (e.g. Cosmos) are considered today one of the most viable alternatives for the highly energy consuming proof-of-work blockchains such as Bitcoin and Eth…
A Distributed Frank-Wolfe Framework for Learning Low-Rank Matrices with the Trace Norm
Wenjie Zheng, Aurélien Bellet, Patrick Gallinari
We consider the problem of learning a high-dimensional but low-rank matrix from a large-scale dataset distributed over several machines, where low-rankness is enforced by a convex…
