The Max Planck Computing and Data Facility (MPCDF, formerly known as RZG) is a cross-institutional competence center of the Max Planck Society to support computational and data sciences. In close collaboration with domain scientists from the Max Planck Institutes, the MPCDF is engaged in the development and optimization of algorithms and applications for high-performance computing and data analytics as well as in the design and implementation of solutions for data-intensive projects. The MPCDF operates a state-of-the-art supercomputer, several mid-range computer systems, and data repositories for various Max Planck Institutes, and provides an up-to-date infrastructure for data management including long-term archival.
