A General Capacity Frontier of Complex Networks
Nicholas Kunz, H. Oliver Gao
From cells to cities, ecosystems to economies, complex networks exhibit peak intensities that define their empirical limit. Estimating these limits traditionally requires domain-sp…
A fast spectral-multigrid Poisson solver in non-Cartesian geometries
Ankush Mandal, Oliver Gressel, Udo Ziegler +1
Accurate and efficient computation of self-gravity is essential in astrophysical fluid dynamics, particularly in spherical and cylindrical geometries where large radial dynamic ran…
On the Limits of Performance Portability in Directive-Based GPU Programming
Alessandro Romeo, Nitin Shukla, Stefano Truzzi +2
The transition of scientific applications to GPU-accelerated exascale systems is constrained by trade-offs between performance, portability, and productivity. This work evaluates t…
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…
