MEDINA: MECCA Development in Accelerators – KPP Fortran to CUDA source-to-source Pre-processor

Abstract

The global climate model ECHAM/MESSy Atmospheric Chemistry (EMAC) is a modular global model that simulates climate change and air quality scenarios. The application includes different sub-models for the calculation of chemical species concentrations, their interaction with land and sea, and the human interaction. The paper presents a source-to-source parser that enables support for Graphics Processing Units (GPU) by the Kinetic Pre-Processor (KPP) general purpose open-source software tool. The requirements of the host system are also described. The source code of the source-to-source parser is available under the MIT License.
