The Computational Earth Sciences (CES) group is a multidisciplinary team with different IT profiles that interacts closely with all the other groups of the Earth Sciences Department. The group provides help and guidance to the scientists with the technical issues relating to their work and develops a framework for the most efficient use of HPC resources. In order to improve the use of the variety of computing resources available at the BSC and in other HPC institutions, a solid software development, profiling and optimisation area has been created for Earth system model codes towards exascale computing, and to provide feedback on this to modellers around Europe. Last but not least, the development of a framework to disseminate the outputs generated by the BSC-ES among the research and service community has been established. This area takes advantage of the unique environment of the BSC where research in Big Data and Artificial Intelligence is already a priority that will be extended in the next few years.
One of the common scopes of the group is the guidance on the use of IT resources, with the aim of Designing and maintaining an IT infrastructure allowing the research teams the accomplishment of their objectives. This involves:
The group is led by Kim Serradell and is organised in 3 teams (“Models and Workflows”, “Performance” and “Data and Diagnostics”) as shown below.
