Short summary
Developing computer models in the earth-system domain is a complex and expensive process that can have a duration measured in years. The supercomputers required to run these models, however, are evolving fast with a proliferation of technologies and associated programming models. As a result there is a need that models be "performance portable" between different supercomputers. This paper investigates a way of doing this through a separation of the concerns of performance and natural science.
