Memory Layouts for GPU-Data Transfer Buffering in SPH
Mladen Ivkovic, Abouzied M. A. Nasar, Tobias Weinzierl +4
The rise in GPU compute speed has outpaced improvements in host-to-device memory transfer speeds, despite the advent of shared-memory superchips. Consequently, memory transfer time…

SPARCS -- combining radiation hydrodynamics with non-equilibrium metal chemistry in the SWIFT astrophysical code
Tsang Keung Chan, Alexander J. Richings, Tom Theuns +3
We present SPARCS, which combines the moment-based radiative transfer method SPH-M1RT with the non-equilibrium metal chemistry solver CHIMES in the modern highly-parallel astrophys…

An extension of C++ with memory-centric specifications for HPC to reduce memory footprints and streamline MPI development
Pawel K. Radtke, Cristian G. Barrera-Hinojosa, Mladen Ivkovic +1
C++ leans towards a memory-inefficient storage of structs: The compiler inserts padding bits, while it is not able to exploit knowledge about the range of integers, enums or bitset…
