Assessing Saiph, a task-based DSL for high-performance computational fluid dynamics
(Elsevier, 2023-10)
Article
Accés restringit per política de l'editorialScientific applications face the challenge of efficiently exploiting increasingly complex parallel and distributed systems. Developing hand-tuned codes is a time-consuming, tedious and hardly reusable task. Reaching high ... -
RISC-V for genome data analysis: opportunities and challenges
(Institute of Electrical and Electronics Engineers (IEEE), 2023)
Text en actes de congrés
Accés obertThe RISC-V ISA has gained significant momentum in High-Performance Computing (HPC) research and market due to its open-source nature, fostering collaborative research and innovation. The ever-growing RISC-V-based ... -
Property rights in servitisation: a practical assessment with reused computers
(Springer, 2022)
Text en actes de congrés
Accés obertThe circular economy of computers is about producing fewer, more durable and reusable products while investing in expanding their life span through a functional service economy. Reuse is often mentioned as a sustainable ... -
Boosting point cloud search with a vector unit
(2023)
Report de recerca
Accés obertModern robots collect and process point clouds to perform accurate registration and segmentation. The most time-consuming kernel within point cloud processing -namely neighbor search- relies on appropriate data structures, ... -
Analyzing and improving hardware modeling of Accel-Sim
(2023-10)
Report de recerca
Accés obertGPU architectures have become popular for executing generalpurpose programs. Their many-core architecture supports a large number of threads that run concurrently to hide the latency among dependent instructions. In modern ... -
Validation, Verification, and Testing (VVT) of future RISC-V powered cloud infrastructures: the Vitamin-V Horizon Europe Project perspective
(Institute of Electrical and Electronics Engineers (IEEE), 2023)
Text en actes de congrés
Accés obertVitamin-V is a project funded under the Horizon Europe program for the period 2023-2025. The project aims to create a complete open-source software stack for RISC-V that can be used for cloud services. This software stack ... -
NEUROPULS: NEUROmorphic energy-efficient secure accelerators based on Phase change materials aUgmented siLicon photonicS
(Institute of Electrical and Electronics Engineers (IEEE), 2023)
Text en actes de congrés
Accés obertThis special session paper introduces the Horizon Europe NEUROPULS project, which targets the development of secure and energy-efficient RISC-V interfaced neuromorphic accelerators using augmented silicon photonics technology. ... -
Energy hardware and workload aware job scheduling towards interconnected HPC environments
(2021-06-17)
Article
Accés obertNew HPC machines are getting close to the exascale. Power consumption for those machines has been increasing, and researchers are studying ways to reduce it. A second trend is HPC machines' growing complexity, with increasing ... -
Charging of the ABR service in ATM networks: a numerical example
(Institute of Electrical and Electronics Engineers (IEEE), 1998-04)
Article
Accés obertThe Available Bit Rate service (ABR) is a "best effort" service intended for traffic which imposes no bound on delay or delay variation. The network guarantees a Minimum Cell Rate (MCR) for an ABR source, which is negotiated ... -
δLTA:: Decoupling camera sampling from processing to avoid redundant computations in the vision pipeline
(Association for Computing Machinery (ACM), 2023)
Text en actes de congrés
Accés obertContinuous Vision (CV) systems are essential for emerging applications like Autonomous Driving (AD) and Augmented/Virtual Reality (AR/VR). A standard CV System-on-a-Chip (SoC) pipeline includes a frontend for image capture ... -
SLIDEX: Sliding window extension for image processing
(Institute of Electrical and Electronics Engineers (IEEE), 2023)
Text en actes de congrés
Accés obertWith the rising need for efficient image processing in emerging applications such as Autonomous Driving (AD) and Augmented/Virtual Reality (AR/VR), many existing solutions do not meet their performance and energy efficiency ... -
QeiHaN: An energy-efficient DNN accelerator that leverages log quantization in NDP architectures
(Institute of Electrical and Electronics Engineers (IEEE), 2023)
Comunicació de congrés
Accés obertThe constant growth of DNNs makes them challenging to implement and run efficiently on traditional computecentric architectures. Some works have attempted to enhance accelerators by adding more compute units and on-chip ...
