Predictive reliability and fault management in exascale systems: State of the art and perspectives
(2020-09)
Article
Open AccessPerformance and power constraints come together with Complementary Metal Oxide Semiconductor technology scaling in future Exascale systems. Technology scaling makes each individual transistor more prone to faults and, due ... -
Supporting time-sensitive and best-effort traffic on a common metro infrastructure
(2020-08)
Article
Open AccessConsiderable research and standardization efforts are being made to support time-sensitive traffic, e.g., generated by applications like Industry 4.0 and 5G fronthaul, on packet networks. This letter focuses on analyzing ... -
Exceeding conservative limits: A consolidated analysis on modern hardware margins
(2020-06)
Article
Open AccessModern large-scale computing systems (data centers, supercomputers, cloud and edge setups and high-end cyber-physical systems) employ heterogeneous architectures that consist of multicore CPUs, general-purpose many-core ... -
Applying cognitive dynamic learning strategies for margins reduction in operational optical networks
(2020-09-01)
Article
Restricted access - publisher's policyToday's optical transport networks are complex already and the support of the new arising services will further increase such complexity. Traditional deterministic network procedures will need to be revisited, especially ... -
Immersive interconnected virtual and augmented reality: a 5G and IoT perspective
(2020-01-01)
Article
Restricted access - publisher's policyDespite remarkable advances, current augmented and virtual reality (AR/VR) applications are a largely individual and local experience. Interconnected AR/VR, where participants can virtually interact across vast distances, ... -
LoRaMoto: a communication system to provide safety awareness among civilians after an earthquake
(Elsevier, 2021-02)
Article
Restricted access - publisher's policyCivilians in areas hit by earthquakes become in particular concerned about the safety of family and friends. However, outages in communications networks following these events limit their capacity to get information. So, ... -
Fast gap-affine pairwise alignment using the wavefront algorithm
(2020-09-11)
Article
Open AccessMotivation Pairwise alignment of sequences is a fundamental method in modern molecular biology, implemented within multiple bioinformatics tools and libraries. Current advances in sequencing technologies press for the ... -
Toward intelligent metasurfaces: the progress from globally tunable metasurfaces to software-defined metasurfaces with an embedded network of controllers
(2020-01-01)
Article
Open AccessMetasurfaces, the ultrathin, 2D version of metamaterials, have recently attracted a surge of attention for their capability to manipulate electromagnetic waves. Recent advances in reconfigurable and programmable metasurfaces ... -
Asynchronous runtime with distributed manager for task-based programming models
(2020-09)
Article
Restricted access - publisher's policyParallel task-based programming models, like OpenMP, allow application developers to easily create a parallel version of their sequential codes. The standard OpenMP 4.0 introduced the possibility of describing a set of ... -
Semi-automatic validation of cycle-accurate simulation infrastructures: The case for gem5-x86
(Elsevier, 2020-11)
Article
Restricted access - publisher's policySince the early 70s, simulation infrastructures have been a keystone in computer architecture research, providing a fast and reliable way to prototype and evaluate ideas for future computing systems. There are different ... -
Real-time optical spectrum monitoring in filterless optical metro networks
(2020-06-17)
Article
Restricted access - publisher's policyFilterless optical networks (FONs) have been proposed as a feasible solution for optical metro networks. In addition, as a result of the shorter distance compared to core optical networks, direct detection optical transmission ... -
Scalability analysis of programmable metasurfaces for beam steering
(Institute of Electrical and Electronics Engineers (IEEE), 2020-01-01)
Article
Open AccessProgrammable metasurfaces have garnered significant attention as they confer unprecedented control over the electromagnetic (EM) response of any surface. Such feature has given rise to novel design paradigms such as ...
