The Leibniz Supercomputing Centre (Leibniz-Rechenzentrum, LRZ) is part of the Bavarian Academy of Sciences and Humanities (Bayerische Akademie der Wissenschaften, BADW). BADW-LRZ is a central site for large scale data archiving and backup. It has been an active player in the area of high performance computing for over 20 years and provides computing power on several different levels. It offers its services to universities in Germany and to publicly funded research institutions, like Max-Planck and Helmholtz Institutes. BADW-LRZ operates a SGI Altix 4700 with nearly ten thousand cores and a peak performance above 60 Teraflop/s as well as a number of general purpose and specialized clusters. BADW-LRZ has more than 150 employees, about 30 of which are working in national or international research projects. BADW- LRZ is member of the Gauss Centre for Supercomputing (GCS), the alliance of the three national supercomputing centres in Germany (FZJ-Jülich, HLRS-Stuttgart, BADW-LRZ-Garching). In PRACE-1IP BADW-LRZ acts as a third party to GCS.
BADW-LRZ has a longstanding and internationally known expertise including research in security, network technologies, IT-Management, IT-operations, data archiving, high performance- and grid computing. In PRACE-1IP BADW-LRZ leads WP9 and contributes to the evolution of the RI, its technical operation, petascaling and future technologies. BADW-LRZ contributes to the leading edge research on new system packaging and infrastructure technologies to minimize the energy needed for cooling HPC systems. As part of PRACE 1IP, BADW-LRZ is currently building a prototype that uses direct free water cooling and reuses the system’s waste heat for heating and cooling purposes. BADW-LRZ is the first HPC site to use this technology in the world.
