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…
An Execution Fingerprint Dictionary for HPC Application Recognition
Thomas Jakobsche, Nicolas Lachiche, Aurélien Cavelan +1
Applications running on HPC systems waste time and energy if they: (a) use resources inefficiently, (b) deviate from allocation purpose (e.g. cryptocurrency mining), or (c) encount…
A Smoothed Particle Hydrodynamics Mini-App for Exascale
Aurélien Cavelan, Rubén M. Cabezón, Michal Grabarczyk +1
The Smoothed Particles Hydrodynamics (SPH) is a particle-based, meshfree, Lagrangian method used to simulate multidimensional fluids with arbitrary geometries, most commonly employ…
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…
Algorithm-Based Fault Tolerance for Parallel Stencil Computations
Aurélien Cavelan, Florina M. Ciorba
The increase in HPC systems size and complexity, together with increasing on-chip transistor density, power limitations, and number of components, render modern HPC systems subject…
