ESM User Forum 2026

An diesem Event nehmen Forschende aus dem Bereich Earth System Modelling sowie User der Hochleistungsrechnersysteme in Jülich teil.

Das Event wird auf Englisch stattfinden.

This meeting brings together researchers from the Earth System Modelling community as well as users of Jülich’s HPC systems. It provides a platform to exchange experiences on novel HPC architectures, discuss recent developments within the community, and foster collaboration across disciplines. This course provides an overview of current developments at JSC and gives scientists working together in the Joint Lab ExaESM (https://www.exaesm.de) as well as in the Jülich MeteoCloud and various research projects the opportunity to discuss their specific issues and challenges.

This course takes place in the rotunda at JSC. We warmly encourage on-site participation to foster lively discussions and networking within the community. A hybrid option will be provided for those who are unable to attend in person. The course will be held in English.

Language:

This course is given in English.

Date:

29-30 June 2026

Thematic Sessions:
