The World Data Centre for Climate. The Earth cannot be reproduced in a laboratory! How, then, can we understand such a system so complex and dynamic? And how can we address that most pressing of questions: What does the climate hold in store for our future and for Earth’s? There is only one tool – the supercomputer – capable of addressing the complexity of world climate and the endless change in both its individual components and their manifold interaction..With a massive 220 terabytes of data, it’s the World Data Centre for Climate (WDCC) who bags the coveted number one spot in our list that features top 10 largest databases across the globe. WDCC, operated by the Max Planck Institute for Meteorology and German Climate Computing Centre, also are the proud owners of a supercomputer worth 35 million Euros. Excluding the 220 terabyte, which are accessible across the web; the WDCC also has an additional 110 terabytes of data that are mainly used for climate simulation and 6 petabytes of extra data’s that are stored in magnetic tapes for easy access.
DKRZ – Partner for Climate Research
DKRZ, the German Climate Computing Center, provides these tools and the associated services which are needed to investigate the processes in the climate system: Computer power, data management, and guidance to use these tools efficiently. As a national service provider, DKRZ operates a supercomputer center to enable climate simulation and provides the scientific users with the technical infrastructure needed for the processing, analysis, and preservation of climate data. This also includes support for related application software, and advice and support in data processing issues. Finally, DKRZ also participates in national and international joint projects with the aim of improving the infrastructure for climate modeling. DKRZ thus constitutes an outstanding research infrastructure for model-based simulations of global climate change and its regional effects. This mission is consistent with the new High-Tech Strategy for climate protection as presented by Prof. Dr. Annette Schavan, Federal Minister for Education and Research, at the second Climate Research Summit in Berlin in October 2007.
DKRZ – Supercomputer
HLRE-3 “Mistral” – The first phase of Mistral, the high performance computing system for Earth system research (HLRE-3), consists of computer components by Atos/Bull, a disk storage system by Xyratex/Seagate and high performance network switches by Mellanox. These components are distributed over 79 racks weighing up to or even more than a ton, which are connected by bundles of fiber fabric.
