Communication in task-parallel ILU-preconditioned CG solversusing MPI + OmpSs
(Wiley, 2017-11-10)
We target the parallel solution of sparse linear systems via iterative Krylov subspace–based methods enhanced with incomplete LU (ILU)-type preconditioners on clusters of multicore processors. In order to tackle large-scale ...
Accelerating the task/data-parallel version of ILUPACK’s BiCG in multi-CPU/GPU configurations
(Elsevier, 2019)
ILUPACK is a valuable tool for the solution of sparse linear systems via iterative Krylov subspace-based methods. Its relevance for the solution of real problems has motivated several efforts to enhance its performance on ...
Object Detection and Recognition for Assistive Robots: Experimentation and Implementation
(Institute of Electrical and Electronics Engineers (IEEE), 2017-09)
Technological advances are being made to assist humans in performing ordinary tasks in everyday settings. A key issue is the interaction with objects of varying size, shape, and degree of mobility. Autonomous assistive ...
Extracting invariant characteristics of sketch maps: Towards place query-by-sketch
(Wiley, 2020-08-01)
In geography, invariant aspects of sketches are essential to study because they reflect the human perception of real-world places. A person's perception of a place can be ex-pressed in sketches. In ...
Modeling Analytical Streams for Social Business Intelligence
(MDPI, 2018-08)
Social Business Intelligence (SBI) enables companies to capture strategic information from public social networks. Contrary to traditional Business Intelligence (BI), SBI has to face the high dynamicity of both the social ...
Multi-sensor localization and navigation for remote manipulation in smoky areas
(SAGE PublicationsInTech, 2013)
When localizing mobile sensors and actuators in indoor environments laser meters, ultrasonic meters or even image processing techniques are usually used. On the other hand, in smoky conditions, due to a fire or building ...
Energy Balance between Voltage-Frequency Scaling and Resilience for Linear Algebra Routines on Low-Power Multicore Architectures
(Elsevier, 2017)
Near Threshold Voltage (NTV) computing has been recently proposed as a technique to save energy, at the cost of incurring higher error rates including, among others, Silent Data Corruption (SDC). In this paper, we evaluate ...
Revisiting conventional task schedulers to exploit asymmetry in multi-core architectures for dense linear algebra operations
(Elsevier, 2017)
Dealing with asymmetry in the architecture opens a plethora of questions related with
the performance- and energy-efficient scheduling of task-parallel applications. While there
exist early attempts to tackle this problem, ...
Exploring stream parallel patterns in distributed MPI environments
(Elsevier, 2019)
In recent years, the large volumes of stream data and the near real-time requirements of data streaming applications have exacerbated the need for new scalable algorithms and programming interfaces for distributed and ...
Comparing the Performance of Indoor Localization Systems through the EvAAL Framework
(MDPI, 2017)
In recent years, indoor localization systems have been the object of significant research activity and of growing interest for their great expected social impact and their impressive business potential. Application areas ...
