Joint Lab Exascale Earth System Modelling

The Joint Lab Exascale Earth System Modelling (JL-ExaESM) enables exascale simulations and develops data handling concepts in order to achieve a breakthrough in the simulation of regional to global climate change, extreme weather events, and the impact on society and ecosystems.

The Joint Lab ExaESM leverages co-design between computer scientists and domain scientists to address the scientific and methodological challenges of Earth system science using simulation and data analytics methods which exploit the exascale capabilities of future supercomputers.

By adopting modern IT concepts for flexible scheduling and federated, hierarchical data management, the flexibility of Earth system model configurations will be increased. In addition, the time-to-solution, encompassing the entire simulation and data analytics chain, will be reduced.

In the JL-ExaESM, scientists from nine Helmholtz institutions work together. The work is splitted in two main activities. The first activity is looking at Exascale Code Scalability. The second activity is looking at Exascale Workflow Scalability of ESM applications.

It’s been decided: Forschungszentrum Jülich will be home to Europe’s first exascale computer. The supercomputer is set to be the first in Europe to surpass the threshold of one trillion (“1” followed by 18 zeros) calculations per second. The system will be acquired by the European supercomputing initiative EuroHPC JU.

The ESM Pills, a poster series developed by the communication & outreach officers at AWI, aim to deliver simple explanations for various ESM-relevant topics. Scientists from all kind of disciplines, as well as students and everybody else who is interested in modelling in general, can inform themselves about what is going on in the world of modelers.
