Abstract
We present first results from the accelerator-enabled distributed-memory Icosahedral Non-hydrostatic (ICON) dynamical core, which will be part of the ICON climate model currently under development at the Max Planck Institute for Meteorology. The accelerator implementation utilizes the evolving OpenACC standard for directives augmenting existing Fortran compilers, such as Cray and PGI. An initial single-node prototype implementation halved time-to-solution on NVIDIA M2090 with respect to Intel Sandybridge for high resolution runs.
