Short summary
We examine an alternative approach to heterogeneous cluster-computing for Earth system models, using the EMAC model as a pilot application on the Dynamical Exascale Entry Platform (DEEP). A set of autonomous interconnected coprocessors complements a conventional HPC cluster to increase computing performance and offer extra flexibility to expose multiple levels of parallelism and achieve better scalability, towards exploiting the potential of a fully Exascale-capable platform.
