Abstract
This application covers the needs for computational geophysical fluid dynamics and ocean modelling at the coastal oceanography group at Department of Marine Sciences at University of Gothenburg. Physical oceanography is a discipline that is a traditional user of supercomputing resources, as it involves solving large partial differential equation systems. This application is a direct continuation of several SNIC/NAISS projects.
The project will include several oceanographic applications ranging from 10 m scales to 100 km scales. Thus, different models will be used for different projects, and will be described in this application. All applications are based on well-developed codes with a large international user groups, all applications are already installed and run on the supercomputer Tetralith. All applications have been developed with HPC resources in mind.
More specific we consider investigations on:
• Tidal energy is an emerging sustainable power source. In order to increase the extractable amount the power plants need to be arranged in farms as for wind power (PhD work). The storage for this project is about 10 TB and includes a large number of files.
• Regional oceanography on the Swedish west coast where we use two different model setups for two different regions. Storage about 10-15 TB when project is active, 2-4 TB when project is idle.
• We will also use storage for a high resolution model for the Baltic Sea. This simulation is used for evaluating how remote sensing products can be used for the Baltic Sea. Storage about 15-20 TB when project is active, 3-5 TB when project is idle.
• Resources will also be allocated depending on the needs to Master students (say 1 student) that would carry out a short internship or thesis during the project period.
