| Zusammenfassung |
| This paper introduces a library of algorithms for representing
cloud microphysics in numerical models. The library is
written in C++, hence the name libcloudph++. In the
current release, the library covers three warm-rain schemes: the single- and
double-moment bulk schemes, and the particle-based scheme with Monte
Carlo coalescence. The three schemes are intended for modelling
frameworks of different dimensionalities and complexities ranging from parcel
models to multi-dimensional cloud-resolving (e.g. large-eddy) simulations. A
two-dimensional (2-D) prescribed-flow framework is used in the paper to
illustrate the library features. The libcloudph++ and all its
mandatory dependencies are free and open-source software. The Boost.units
library is used for zero-overhead dimensional analysis of the code at compile
time. The particle-based scheme is implemented using the Thrust library that
allows one to leverage the power of graphics processing units (GPU),
retaining the possibility of compiling the unchanged code for execution on
single or multiple standard processors (CPUs). The paper includes a complete
description of the programming interface (API) of the library and a
performance analysis including comparison of GPU and CPU set-ups. |
