Earth System Modelling Symposium

JSC is organizing the Earth System Modelling (ESM) Symposium from 27 to 29 May 2019. The symposium brings together users of the Helmholtz ESM partition on JUWELS as well as computational scientists and system administrators from JSC. The event will take stock of Earth system modelling achievements that can be realized through the ESM partition, form the basis of problem-solving tutorials (with a focus on GPU usage), and provide a forum for discussing the future use of this resource and its integration in two planned Helmholtz-wide initiatives: Pilot Lab Exascale Earth System Modelling (PL-EESM) and Joint Lab EESM.

In 2016/17, the Helmholtz Association applied for and received supplementary funding for an additional compute partition (ESM partition) on the next-generation Tier-0/1 system JUWELS at Forschungszentrum Jülich, which is specifically dedicated to Earth system science simulations and big data workflows. This extension arrives in two instalments: the first part has been in operation since July 2018, while the second part will be set up in 2020.

The core concept of the Helmholtz ESM partition is to provide dedicated next-generation Tier-0/1 capability to Earth system science. This can be used for next-generation scientific software implementation, testing, performance analysis, and tuning, on the one hand, and for production runs and preparation of subsequent frontier simulations, on the other hand. Since the ESM partition is not realized as dedicated hardware, but instead as an equivalent share of compute time on the entire JUWELS system, it offers enormous flexibility to Earth system scientists within the Helmholtz Association. They can utilize the dedicated partition under their own governance, while at the same time making full use of the Tier-0/1 system at JSC, for example to perform frontier simulations. This concept offers strong synergies in terms of code optimization and project distribution within a fully equipped HPC system.
