Simulation of the performance and scalability of message passing interface (MPI) communications of atmospheric models running on exascale supercomputers
<p>In this study, we identify the key message passing interface (MPI) operations required in atmospheric modelling; then, we use a skeleton program and a simulation framework (based on SST/macro simulation package) to simulate these MPI operations (transposition, halo exchange, and allredu...
