    User's talk

    There is overwhelming evidence that new power sources and more complex geometries are strictly necessary for explaining the observed light curves of certain astrophysical transients, e.g. supernovae in the presence of surrounding medium. Numerical models are challenging due the need of performing radiation-hydrodynamic simulations across a wide dynamic range of both time and space, which...

    User's talk

    This talk/poster investigates the performance of the distributed k-Wave toolbox on Barbora, Karolina and LUMI clusters. The solver uses 1D decomposition of the k-space corrected pseduospectral method heavily employing the distributed FFTW library. The goal is to show the strong and weak scaling on domains up to 3072^3 grid points (3.6TB of RAM) using up to 3072 compute cores. The comparison...

    User's talk

    The PALM model system [1] is an open-source, HPC-enabled, extensible large-eddy simulation (LES) modelling system which includes components for many related processes that are necessary for a complex environmental modelling in micro-scale, such as resolved urban climate simulations in the street level [2]. These simulations are vital for studying the adverse effects of urbanization and climate...
