Astrophysics on GPUs: introducing AGILE 1.0
Oliver Porth, Adrian Kelly, Olaf Willocx +10
We present AGILE, a GPU-enabled adaptive mesh refinement (AMR) framework for the solution of (near-) conservation laws which occur in astro- and solar-physical applications. AGILE…
foap4: Adaptive mesh refinement with OpenACC, MPI, and p4est
Jannis Teunissen, Héctor R. Olivares Sánchez, Jesse Vos +10
GPUs and other accelerators are increasingly used for scientific computing. In the future, we want to add GPU support to parallel adaptive mesh refinement (AMR) codes written in Fo…
Thermal instability in coronal loops: linking eigenvalue spectra to time-dependent evolution
Adrian Kelly, Rony Keppens, Jordi De Jonghe
Cool, dense condensations such as coronal rain and prominences suggest that coronal plasma can undergo runaway radiative cooling. Connecting this behaviour to linear thermal modes…
The hydrodynamic thermal continuum, with applications to stratified atmospheres and 1D coronal loop models
Rony Keppens, Jordi De Jonghe, Adrian Kelly +2
Using both analytical and numerical means, we demonstrate that linear stability analysis of a hydrodynamic stratified atmosphere or a 1D coronal loop model in non-adiabatic setting…
