Heuristic-based task-to-thread mapping in multi-core processors
(Institute of Electrical and Electronics Engineers (IEEE), 2022)
Conference report
Open AccessOpenMP can be used in real-time applications to enhance system performance. However, predictability of OpenMP applications is still a challenge. This paper investigates heuristics for the mapping of OpenMP task graphs in ... -
OmpSs-2@Cluster: Distributed memory execution of nested OpenMP-style tasks
(Springer Nature, 2022)
Conference report
Restricted access - publisher's policyState-of-the-art programming approaches generally have a strict division between intra-node shared memory parallelism and inter-node MPI communication. Tasking with dependencies offers a clean, dependable abstraction for ... -
Deep reinforcement learning meets graph neural networks: Exploring a routing optimization use case
(Elsevier, 2022-12-01)
Article
Restricted access - publisher's policyDeep Reinforcement Learning (DRL) has shown a dramatic improvement in decision-making and automated control problems. Consequently, DRL represents a promising technique to efficiently solve many relevant optimization ... -
Sliding window support for image processing in autonomous vehicles
(2022)
Conference report
Open AccessCamera-based autonomous driving extensively ma-nipulates images for object detection, object tracking, or camera-based localization tasks. Therefore, efficient and fast image processing is crucial in those systems. ... -
Functional and timing implications of transient faults in critical systems
(Institute of Electrical and Electronics Engineers (IEEE), 2022)
Conference report
Open AccessEmbedded systems in critical domains, such as auto-motive, aviation, space domains, are often required to guarantee both functional and temporal correctness. Considering transient faults, fault analysis and mitigation ... -
Sources of single event effects in the NVIDIA Xavier SoC family under proton irradiation
(Institute of Electrical and Electronics Engineers (IEEE), 2022)
Conference report
Open AccessIn this paper we characterise two embedded GPU devices from the NVIDIA Xavier family System-on-Chip (SoC) using a proton beam. We compare the NVIDIA Xavier NX and Industrial devices, that respectively target commercial and ... -
Graph signal reconstruction techniques for IoT air pollution monitoring platforms
(Institute of Electrical and Electronics Engineers (IEEE), 2022-08-03)
Article
Open AccessAir pollution monitoring platforms play a very important role in preventing and mitigating the effects of pollution. Recent advances in the field of graph signal processing have made it possible to describe and analyze air ... -
DTexL: Decoupled raster pipeline for texture locality
(Institute of Electrical and Electronics Engineers (IEEE), 2022)
Conference report
Open AccessContemporary GPU architectures have multiple shader cores and a scheduler that distributes work (threads) among them, focusing on load balancing. These load balancing techniques favor thread distributions that are detrimental ... -
A low-power IoT device for measuring water table levels and soil moisture to ease increased crop yields
(2022-09-09)
Article
Open AccessThe simultaneous measurement of soil water content and water table levels is of great agronomic and hydrological interest. Not only does soil moisture represent the water available for plant growth but also water table ... -
Building a Digital Twin for network optimization using graph neural networks
(2022-11-09)
Article
Open AccessNetwork modeling is a critical component of Quality of Service (QoS) optimization. Current networks implement Service Level Agreements (SLA) by careful configuration of both routing and queue scheduling policies. However, ... -
End-to-end QoS for the open source safety-relevant RISC-V SELENE platform
(arXiv, 2022)
Conference report
Open AccessThis paper presents the end-to-end QoS approach to provide performance guarantees followed in the SELENEplatform, a high-performance RISC-V based heterogeneous SoC for safety-related real-time systems. Our QoS approach ... -
Towards EXtreme scale technologies and accelerators for euROhpc hw/Sw supercomputing applications for exascale: The TEXTAROSSA approach
(2022-11)
Article
Restricted access - publisher's policyIn the near future, Exascale systems will need to bridge three technology gaps to achieve high performance while remaining under tight power constraints: energy efficiency and thermal control; extreme computation efficiency ...
