Application of the VUV and the soft x-ray systems on JET for the study of intrinsic impurity behavior in neon seeded hybrid discharges
(AIP Publishing, 2018-10-24)
Article
Open AccessThis paper reports on impurity behavior in a set of hybrid discharges with Ne seeding—one of the techniques considered to reduce the power load on reactor walls. A series of experiments carried out with light gas injection ... -
Extension of the parallel Sparse Matrix Vector Product (SpMV) for the implicit coupling of PDEs on non-matching meshes
(Elsevier, 2018-09-15)
Article
Restricted access - publisher's policyThe Sparse Matrix Vector Product (SpMV) is one of the main operations of iterative solvers, and, in a parallel context, it is also the siege of point-to-point communications between the neighboring MPI processes. The ... -
A stochastic rupture earthquake code based on the fiber bundle model (TREMOL v0.1): application to Mexican subduction earthquakes
(European Geosciences Union (EGU), 2018-05-08)
Article
Open AccessIn general terms, earthquakes are the result of brittle failure within the heterogeneous crust of the Earth. However, the rupture process of a heterogeneous material is a complex physical problem that is difficult to model ... -
High-Integrity GPU Designs for Critical Real-Time Automotive Systems
(IEEE, 2019-04-16)
Conference lecture
Open AccessAutonomous Driving (AD) imposes the use of highperformance hardware, such as GPUs, to perform object recognition and tracking in real-time. However, differently to the consumer electronics market, critical real-time AD ... -
Parallel mesh partitioning based on space filling curves
(Elsevier, 2018-09)
Article
Restricted access - publisher's policyLarger supercomputers allow the simulation of more complex phenomena with increased accuracy. Eventually this requires finer and thus also larger geometric discretizations. In this context, and extrapolating to the Exascale ... -
Evaluating the roles of detailed endocardial structures on right ventricular haemodynamics by means of CFD simulations
(Wiley, 2018-09)
Restricted access - publisher's policyComputational modelling plays an important role in right ventricular (RV) haemodynamic analysis. However, current approaches use smoothed ventricular anatomies. The aim of this study is to characterise RV haemodynamics ... -
Large eddy simulation for automotive aerodynamics with Alya
(2018-07-09)
Conference lecture
Open AccessThe prodigious potential offered by the ever-growing computing infrastructure is fostering the use of large eddy simulation for automotive aerodynamics. This approach, which resolves the larger dynamically important eddies ... -
Mesh generation, sizing and convergence for onshore and offshore wind farm Atmospheric Boundary Layer flow simulation with actuator discs
(Elsevier, 2018-12)
Article
Open AccessA new mesh generation process for wind farm modeling is presented together with a mesh convergence and sizing analysis for wind farm flow simulations. The generated meshes are tailored to simulate Atmospheric Boundary Layer ... -
Recent EUROfusion Achievements in Support of Computationally Demanding Multiscale Fusion Physics Simulations and Integrated Modeling
(American Nuclear Society, 2018-02-21)
Article
Open AccessIntegrated modeling (IM) of present experiments and future tokamak reactors requires the provision of computational resources and numerical tools capable of simulating multiscale spatial phenomena as well as fast transient ... -
Observations and modelling of ion cyclotron emission observed in JET plasmas using a sub-harmonic arc detection system during ion cyclotron resonance heating
(IOP Publishing:, 2018-07-10)
Article
Open AccessMeasurements are reported of electromagnetic emission close to the cyclotron frequency of energetic ions in JET plasmas heated by waves in the ion cylotron range of frequencies (ICRF). Hydrogen was the majority ion species ... -
A Massively Parallel Algorithm for the Approximate Calculation of Inverse p-th Roots of Large Sparse Matrices
(Association for Computing Machinery (ACM), 2018-07)
Conference lecture
Open AccessWe present the submatrix method, a highly parallelizable method for the approximate calculation of inverse p-th roots of large sparse symmetric matrices which are required in different scientific applications. Following ... -
Linear scaling DFT calculations for large tungsten systems using an optimized local basis
(Elsevier, 2018-05)
Article
Open AccessDensity functional theory (DFT) has become a standard tool for ab-initio simulations for a wide range of applications. While the intrinsic cubic scaling of DFT was for a long time limiting the accessible system size to ...
