DKRZ - Partner for Climate Research

to provide high performance computing platforms, sophisticated and high capacity data management and superior service for premium climate science.

About us:

The German Climate Computing Center is a national service facility and a major partner for climate research. Our high performance computers, data storage and services form the central research infrastructure for simulation-based climate science in Germany.

High Performance Computer:

Climate simulations require high performance supercomputers and data storage systems. The systems at DKRZ are optimized for the data-intensive needs of climate science and rank among the largest systems employed for scientific computing worldwide.


DKRZ’s expert staff support climate scientists in the optimal utilization of the systems and offer a range of services around climate models, climate simulations and climate data: from support in carrying out climate simulations, through parallelization and optimization of the simulation programs, via management, storage and publication of the data, up to analysis and visualization of the simulation results.

Projects and Partners:

Cutting-edge research requires solid networks and strong partners. Get to know the partners and network and find out about the scientific topics handled with the support of DKRZ. DKRZ itself does not conduct climate research but is a partner in various scientific projects with the aim of further improving support for climate science.


Climate change and model-based climate projections are time and time again at the center of public attention. On this page, you will find a variety of media and information materials illustrating, among other things, the results of climate research obtained through the assistance of DKRZ and its high performance computers.

ISC24: Levante on rank 92 of TOP500 list

Under the motto “Reinventing HPC”, the ISC’24 takes place in Hamburg from May 12th to 16th, 2024. As the largest international HPC conference, with a diverse program of talks and exhibitions, it offers a platform to find out about innovations and applications and to network. The DKRZ participates to the ISC program with poster presentations, sofa talks, the Student Cluster Competition and personal network meetings. On the first day of the conference, the new TOP500 list of the most powerful HPC systems was released, on which the DKRZ supercomputer Levante was ranked on 92. This makes it the fifth strongest German system.
