Kinetic approach to relativistic dissipation
A. Gabbana, M. Mendoza, S. Succi +1
Despite a long record of intense efforts, the basic mechanisms by which dissipation emerges from the microscopic dynamics of a relativistic fluid still elude a complete understandi…
Optimization of Lattice Boltzmann Simulations on Heterogeneous Computers
E. Calore, A. Gabbana, S. F. Schifano +1
High-performance computing systems are more and more often based on accelerators. Computing applications targeting those systems often follow a host-driven approach in which hosts…
Evaluation of DVFS techniques on modern HPC processors and accelerators for energy-aware applications
Enrico Calore, Alessandro Gabbana, Sebastiano Fabio Schifano +1
Energy efficiency is becoming increasingly important for computing systems, in particular for large scale HPC facilities. In this work we evaluate, from an user perspective, the us…
Towards a unified lattice kinetic scheme for relativistic hydrodynamics
A. Gabbana, M. Mendoza, S. Succi +1
We present a systematic derivation of relativistic lattice kinetic equations for finite-mass particles, reaching close to the zero-mass ultra-relativistic regime treated in the pre…
Performance and Portability of Accelerated Lattice Boltzmann Applications with OpenACC
E. Calore, A. Gabbana, J. Kraus +2
An increasingly large number of HPC systems rely on heterogeneous architectures combining traditional multi-core CPUs with power efficient accelerators. Designing efficient applica…
Massively parallel lattice-Boltzmann codes on large GPU clusters
E. Calore, A. Gabbana, J. Kraus +3
This paper describes a massively parallel code for a state-of-the art thermal lattice- Boltzmann method. Our code has been carefully optimized for performance on one GPU and to hav…
