ngFEOSAD. Coarray and GPU accelerated radiation hydrodynamics code for studying initial stages of star and planet formation

26 Sept 2024

Speaker: Eduard Vorobyov (University of Vienna)

Abstract:

Numerical simulations of the initial stages of star and planet formation requires developing specialized codes, which can capture large spatial scales and employ efficient parallelization techniques. We will discuss the problems and their solutions, which we encountered when developing the nested-grids numerical gravito-radiation hydrodynamics code ngFEOSAD. Subtilties of the interface between the coarray FORTRAN, a fast and user-friendly alternative to MPI, and CUDA FORTRAN parallelization techniques will be presented.
