Scanflow-K8s: agent-based framework for autonomic management and supervision of ML workflows in Kubernetes clusters
(Institute of Electrical and Electronics Engineers (IEEE), 2022)
Conference report
Open AccessMachine Learning (ML) projects are currently heavily based on workflows composed of some reproducible steps and executed as containerized pipelines to build or deploy ML models efficiently because of the flexibility, ... -
Running OpenMp applications efficiently on an everything-shared SDSM
(Institute of Electrical and Electronics Engineers (IEEE), 2004)
Conference lecture
Open AccessTraditional software distributed shared memory (SDSM) systems modify the semantics of a real hardware shared memory system by relaxing the coherence semantic and by limiting the memory regions that are actually shared. ... -
Fine-grain task-parallel algorithms for matrix factorizations and inversion on many-threaded CPUs
(Wiley (John Wiley & Sons), 2022-04-07)
Article
Open AccessWe extend a two-level task partitioning previously applied to the inversion of dense matrices via Gauss–Jordan elimination to the more challenging QR factorization as well as the initial orthogonal reduction to band form ... -
Vulnerable road users and connected autonomous vehicles interaction: a survey
(Multidisciplinary Digital Publishing Institute (MDPI), 2022-06-18)
Article
Open AccessThere is a group of users within the vehicular traffic ecosystem known as Vulnerable Road Users (VRUs). VRUs include pedestrians, cyclists, motorcyclists, among others. On the other hand, connected autonomous vehicles ... -
Exploiting pipelined executions in OpenMP
(Institute of Electrical and Electronics Engineers (IEEE), 2003)
Conference report
Open AccessWe propose a set of extensions to the OpenMP programming model to express point-to-point synchronisation schemes. This is accomplished by defining, in the form of directives, precedence relations among the tasks that are ... -
Introducing polyglot-based data-flow awareness to time-series data stores
(Institute of Electrical and Electronics Engineers (IEEE), 2022-06-30)
Article
Open AccessThe rising interest in extracting value from data has led to a broad proliferation of monitoring infrastructures, most notably composed by sensors, intended to collect this new oil. Thus, gathering data has become fundamental ... -
Systematic detection of anomalous ionospheric perturbations above LEOs from GNSS POD Data including possible tsunami signatures
(Institute of Electrical and Electronics Engineers (IEEE), 2022-06-13)
Article
Open AccessIn this article, we show the capability of a global navigation satellite system (GNSS) precise orbit determination (POD) low Earth orbit (LEO) data to detect anomalous ionospheric disturbances in the spectral range of the ... -
FASE: A fast, accurate and seamless emulator for custom numerical formats
(Institute of Electrical and Electronics Engineers (IEEE), 2022)
Conference report
Open AccessDeep Neural Networks (DNNs) have become ubiquitous in a wide range of application domains. Despite their success, training DNNs is an expensive task that has motivated the use of reduced numerical precision formats to ... -
Exploring the predictability of MPI messages
(IEEE Computer Society, 2003)
Conference report
Open AccessScalability to a large number of processes is one of the weaknesses of current MPI implementations. Standard implementations are able to scale to hundreds of nodes, but none beyond that. The main problem of current ... -
Complex pipelined executions in OpenMP parallel applications
(Institute of Electrical and Electronics Engineers (IEEE), 2001)
Conference report
Open AccessThis paper proposes a set of extensions to the OpenMP programming model to express complex pipelined computations. This is accomplished by defining, in the form of directives, precedence relations among the tasks originated ... -
PyCOMPSs as an instrument for translational computer science
(2022-03-01)
Article
Open AccessWith the advent of distributed computing, the need for frameworks that facilitate its programming and management has also appeared. These tools have typically been used to support the research on application areas that ... -
Dynamic resource allocation for efficient parallel CFD simulations
(Elsevier, 2022-06-28)
Article
Restricted access - publisher's policyCFD users of supercomputers usually resort to rule-of-thumb methods to select the number of subdomains (partitions) when relying on MPI-based parallelization. One common approach is to set a minimum number of elements or ...
