Interaction between the ejecta, the accretion disk, and the secondary star in the recurrent nova system U Sco
Joana Figueira, Jordi Jose, Ruben Cabezon +1
Most efforts in the modeling of recurrent novae have centered on the initial phases of the explosion and ejection, overlooking the subsequent interaction of the ejecta, first with…
Cornerstone: Octree Construction Algorithms for Scalable Particle Simulations
Sebastian Keller, Aurélien Cavelan, Rubén Cabezon +2
This paper presents an octree construction method, called Cornerstone, that facilitates global domain decomposition and interactions between particles in mesh-free numerical simula…
Conservative, density-based smoothed particle hydrodynamics with improved partition of the unity and better estimation of gradients
Domingo García-Senz, Rubén M. Cabezón, José A. Escartín
The correct evaluation of gradients is at the cornerstone of the smoothed particle hydrodynamics (SPH) technique. Using an integral approach to estimate gradients has proven to enh…
Two-level Dynamic Load Balancing for High Performance Scientific Applications
Ali Mohammed, Aurelien Cavelan, Florina M. Ciorba +2
Scientific applications are often complex, irregular, and computationally-intensive. To accommodate the ever-increasing computational demands of scientific applications, high-perfo…
Finding Neighbors in a Forest: A b-tree for Smoothed Particle Hydrodynamics Simulations
Aurélien Cavelan, Rubén M. Cabezón, Jonas H. M. Korndorfer +1
Finding the exact close neighbors of each fluid element in mesh-free computational hydrodynamical methods, such as the Smoothed Particle Hydrodynamics (SPH), often becomes a main b…
SPH-EXA: Enhancing the Scalability of SPH codes Via an Exascale-Ready SPH Mini-App
Danilo Guerrera, Aurélien Cavelan, Rubén M. Cabezón +6
Numerical simulations of fluids in astrophysics and computational fluid dynamics (CFD) are among the most computationally-demanding calculations, in terms of sustained floating-poi…
