Title
MPI vs Fortran coarrays beyond 100k cores: 3D cellular automata
Abstract
•A Fortran 2018 coarrays cellular automata (CA) library for HPC is presented.•Scaling up to 110k cores (full machine capacity) has been achieved.•Useful 3D magnetisation results have been achieved.•Detailed profiling of coarrays vs MPI magnetisation miniapps is presented.•Coarrays optimisation in Cray compiler is lagging behind MPI.
