A robust super-time-stepping scheme for Ohmic and ambipolar diffusion
Giancarlo Mattia, Mario Flock, David Melon Fuksman +3
Context. Non-ideal magnetohydrodynamics (MHD) is a key tool for modeling magnetic flux transport in astrophysical systems such as molecular clouds, protostellar cores, and protopla…
The PLUTO Code on GPUs: Offloading Lagrangian Particle Methods
Alessio Suriano, Stefano Truzzi, Agnese Costa +5
The Lagrangian Particles (LP) module of the PLUTO code offers a powerful simulation tool to predict the non-thermal emission produced by shock accelerated particles in large-scale…
2D or not 2D? Exploring 3D relativistic magnetic reconnection dynamics with highly accurate numerical simulations
Vittoria Berta, Matteo Bugli, Andrea Mignone +3
Fast reconnection in magnetically dominated plasmas is widely invoked in models of dissipation in pulsar winds, gamma-ray flares in the Crab nebula, and to explain the radio nanosh…
EuroHPC SPACE CoE: Redesigning Scalable Parallel Astrophysical Codes for Exascale
Nitin Shukla, Alessandro Romeo, Caterina Caravita +36
High Performance Computing (HPC) based simulations are crucial in Astrophysics and Cosmology (A&C), helping scientists investigate and understand complex astrophysical phenomena. T…
The PLUTO Code on GPUs: A First Look at Eulerian MHD Methods
Marco Rossazza, Andrea Mignone, Matteo Bugli +7
We present preliminary performance results of gPLUTO, the new GPU-optimized implementation of the PLUTO code for computational plasma astrophysics. Like its predecessor, gPLUTO emp…
PyPLUTO: a data analysis Python package for the PLUTO code
Giancarlo Mattia, Daniele Crocco, David Melon Fuksman +5
In recent years, numerical simulations have become indispensable for addressing complex astrophysical problems. The MagnetoHydroDynamics (MHD) framework represents a key tool for i…
