An early experience of regional ocean modelling on intel many integrated core architecture

Ocean modelling is an inherently complex phenomenon within the earth system framework which poses a challenge to the earth and computational scientists. Simulation of wide temporal and spatial scales in real-time / near real-time necessitates computational scientists to explore new performance enhancing architectures and simulation methods. Due to the spectra of the scales of motion, the computational requirements of ocean forecasting are relatively higher than that of numerical weather prediction. To some extent, the rapidly evolving computer technology provide solutions to this. In this paper, we present initial attempts in porting a high resolution regional ocean model on an Intel MIC based hybrid system. We discuss the challenges and issues to be addressed in achieving an efficient implementation of an ocean modelling system.
