| Título: | FAMOUS, faster: using parallel computing techniques to accelerate the FAMOUS/HadCM3 climate model with a focus on the radiative transfer algorithm |
Autor: | Hanappe, Peter; Steels, Luc CSIC ORCID | Fecha de publicación: | 2011 | Editor: | European Geosciences Union | Citación: | Geoscientific Model Development 4(3): 835-844 (2011) | Resumen: | We have optimised the atmospheric radiation algorithm of the FAMOUS climate model on several hardware platforms. The optimisation involved translating the Fortran code to C and restructuring the algorithm around the computation of a single air column. Instead of the existing MPI-based domain decomposition, we used a task queue and a thread pool to schedule the computation of individual columns on the available processors. Finally, four air columns are packed together in a single data structure and computed simultaneously using Single Instruction Multiple Data operations. | Descripción: | This work is distributed under the Creative Commons Attribution 3.0 License.-- et al. | Versión del editor: | http://dx.doi.org/10.5194/gmd-4-835-2011 | URI: | http://hdl.handle.net/10261/127867 | DOI: | 10.5194/gmd-4-835-2011 | ISSN: | 1991-959X | E-ISSN: | 1991-9603 |
