MPCDF picture of the month: July 2026
Our colleague Nastassya from the AI department is standing in front of a very windy rack. The computer system seen here is cooled by an airflow that is blown through the raised floor into the racks. The servers then heat up the air and release it as warm exhaust. However, modern supercomputers nowadays have such a high power density that this cooling strategy is no longer sufficient. Instead, the components are cooled directly by a water flow. As a side effect, the computer halls become quieter, creating a better working environment for technicians.
High-performance computing and data analytics application support for the MPG
The MPCDF provides high-level support for the development, optimization, analysis and visualization of high-performance computing (HPC) and data analytics (HPDA) applications to Max-Planck Institutes with high-end computing needs, e.g. in astrophysics, fusion research, materials and bio sciences, polymer research, and theoretical chemistry.

IBM tape library
IBM TS4500 tape library. In total, MPCDF tape libraries provide a capacity of more than 105,000 LTO tape slots and 200 LTO tape drives and store more than 300 Petabytes of long-term archives (HPSS) and backups (IBM Spectrum Protect). The data archives of Max-Planck scientists include experiment and simulation data from many science areas, e.g. from life and materials sciences, astro and fusion research, and also treasures of the World Heritage like sound recordings of endangered languages or images of historic frescoes.
National and international projects
The MPCDF, in partnership with different Max Planck Institutes is engaged in several national and international projects and research consortia, such as EU Centers of Excellence, with a focus in high-performance computing, artificial intelligence, data analytics, and data management.
Science use cases
The brochure "High-Performance Computing and Data Science in the Max Planck Society" shows examples of cutting-edge science in the Max Planck Society which were enabled by MPCDF services.
