The article discusses advancements in global ocean simulations, particularly focusing on achieving finer spatial resolutions. While only a few simulations have successfully gone below 5 km resolution, they require substantial computational resources. Innovations such as new numerical methods and optimizations for GPU scalability are highlighted as crucial for improving performance in ocean modeling. The analysis also reveals enhancements in energy efficiency and operational capacity, reflecting the need for continuous development in this computationally intensive field.
In 2014, MITgcm was used to perform the one year, tidal-forced ice-ocean simulation 'LLC4320', exhibiting 2.2 km horizontal resolution with 90 vertical levels, but at high computational cost.
Only three global ocean simulations have achieved finer than 5 km resolutions, all requiring tremendous computational resources, highlighting the ongoing challenges in ocean simulation.
Innovative numerical methods and GPU scalability optimizations are critical for improving ocean simulation performance while maintaining necessary resolution and accuracy.
The performance results indicate that advancements in numerical methods and hardware can significantly reduce computational expenditure and enhance energy efficiency for ocean simulations.
