[PDF][PDF] SwarmSGD: Scalable decentralized SGD with local updates

…, D Alistarh, A Sharma, I Markov, V Aksenov - arXiv preprint arXiv …, 2019 - parsa.epfl.ch
The ability to scale distributed optimization to large node counts has been one of the main
enablers of recent progress in machine learning. To this end, several techniques have been …

Provably and practically efficient granularity control

UA Acar, V Aksenov, A Charguéraud… - Proceedings of the 24th …, 2019 - dl.acm.org
Over the past decade, many programming languages and systems for parallel-computing
have been developed, eg, Fork/Join and Habanero Java, Parallel Haskell, Parallel ML, and …

Lazy self-adjusting bounded-degree networks for the matching model

…, P Shyamsukha, R Sama, V Aksenov… - … -IEEE Conference on …, 2022 - ieeexplore.ieee.org
Self-adjusting networks (SANs) utilize novel optical switching technologies to support dynamic
physical network topology reconfiguration. SANs rely on online algorithms to exploit this …

The splay-list: A distribution-adaptive concurrent skip-list

V Aksenov, D Alistarh, A Drozdova… - Distributed Computing, 2023 - Springer
The design and implementation of efficient concurrent data structures has seen significant
attention. However, most of this work has focused on concurrent data structures providing …

A concurrency-optimal binary search tree

V Aksenov, V Gramoli, P Kuznetsov, A Malova… - Euro-Par 2017: Parallel …, 2017 - Springer
The paper presents the first concurrency-optimal implementation of a binary search tree (BST).
The implementation, based on a standard sequential implementation of a partially-…

Self-adjusting linear networks with ladder demand graph

…, I Salem, S Schmid, V Aksenov - arXiv preprint arXiv …, 2022 - arxiv.org
Self-adjusting networks (SANs) have the ability to adapt to communication demand by
dynamically adjusting the workload (or demand) embedding, ie, the mapping of communication …

Brief announcement: Parallel dynamic tree contraction via self-adjusting computation

UA Acar, V Aksenov, S Westrick - … of the 29th ACM Symposium on …, 2017 - dl.acm.org
Dynamic algorithms are used to compute a property of some data while the data undergoes
changes over time. Many dynamic algorithms have been proposed but nearly all are …

[HTML][HTML] Recovering rearranged cancer chromosomes from karyotype graphs

S Aganezov, I Zban, V Aksenov, N Alexeev… - BMC …, 2019 - Springer

chromosomal karyotypes. Structural and copy number variations in cancer genomes can be …

Brief announcement: performance prediction for coarse-grained locking

V Aksenov, D Alistarh, P Kuznetsov - … of the 2018 ACM Symposium on …, 2018 - dl.acm.org
A standard design pattern found in many concurrent data structures, such as hash tables or
ordered containers, is an alternation of parallelizable sections that incur no data conflicts and …

In the Search of Optimal Tree Networks: Hardness and Heuristics

…, P Martynov, S Pankratov, V Aksenov… - arXiv preprint arXiv …, 2024 - arxiv.org
Demand-aware communication networks are networks whose topology is optimized toward
the traffic they need to serve. These networks have recently been enabled by novel optical …
