Zusammenfassung |
In this article we present a new version of the Ocean Atmosphere Sea Ice Soil
coupling software (OASIS4). With this new fully parallel OASIS4
coupler we target the needs of Earth system modelling in its full complexity.
The primary focus of this article is to describe the design of the
OASIS4 software and how the coupling software drives the whole coupled
model system ensuring the synchronization of the different component models.
The application programmer interface (API) manages the coupling exchanges
between arbitrary climate component models, as well as the input and output
from and to files of each individual component. The OASIS4 Transformer
instance performs the parallel interpolation and transfer of the coupling
data between source and target model components. As a new core technology for
the software, the fully parallel search algorithm of OASIS4 is
described in detail. First benchmark results are discussed with simple test
configurations to demonstrate the efficiency and scalability of the software
when applied to Earth system model components. Typically the compute time
needed to perform the search is in the order of a few seconds and is only
weakly dependant on the grid size. |
