Presentation
Computational Radiation Hydrodynamics with FleCSI
DescriptionPhotons are essential in many matter-light interaction systems, with applications in physics (e.g., core-collapse supernovae) and engineering (e.g., neutron transport). Although the theory of radiating fluids has been established since the 1980s, developing robust and efficient numerical simulations remains an active research area.
Using the FleCSI framework, we developed a radiation hydrodynamics code called HARD (Hydrodynamics And Radiative Diffusion), which is scalable and portable across various HPC architectures and computing systems. FleCSI provides us with a task-based parallelism framework supported by different backends such as MPI, HPX, and Legion. The on-node parallelism is then handled through Kokkos targeting CPU and GPU architectures.
This poster presents both our achievements in the physics implementation and its adaptation to the task-based model, and also the benchmark of the different backends using FleCSI on Los Alamos National Laboratory supercomputers.
