Performance Portability for Fortran CFD Software with GALÆXI
With GPU acceleration now ubiquitous in HPC, porting existing simulation software to leverage GPUs is more important than ever. Although many GPU programming models exist, they often have limited or no support for Fortran, making porting existing Fortran scientific codes to multiple computing architectures an extra struggle. This webinar guides you through one solution of…
