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…
SWIFT: A modern highly-parallel gravity and smoothed particle hydrodynamics solver for astrophysical and cosmological applications
Matthieu Schaller, Josh Borrow, Peter W. Draper +24
Numerical simulations have become one of the key tools used by theorists in all the fields of astrophysics and cosmology. The development of modern tools that target the largest ex…
GEAR-RT: Towards Exa-Scale Moment Based Radiative Transfer For Cosmological Simulations Using Task-Based Parallelism And Dynamic Sub-Cycling with SWIFT
Mladen Ivkovic
The development and implementation of GEAR-RT, a radiative transfer solver using the M1 closure in the open source code SWIFT, is presented, and validated using standard tests for…
ACACIA: a new method to produce on-the-fly merger trees in the RAMSES code
Mladen Ivkovic, Romain Teyssier
The implementation of ACACIA, a new algorithm to generate dark matter halo merger trees with the Adaptive Mesh Refinement (AMR) code RAMSES, is presented. The algorithm is fully pa…
