Break-through values achieved for databases, climate computing and grid technologies

14.11.2005


High-tech in Earth System Science at the Max Planck Institute for Meteorology, Hamburg, Germany



Record-breaking high-tech has been successfully employed in Earth System Science at the Max Planck Institute for Meteorology (MPI-M) in Hamburg, Germany.

- The largest database in the world under the free Linux operating system has been installed in Hamburg by the Wold Data Centre for Climate (WDCC) and the German Climate Computing Centre (DKRZ) . This is confirmed in the international ranking list of the world’s largest databases published by the Winter Corporation in September. NEC installed the database system at the DKRZ three years ago in conjunction with a 1.5 teraflop NEC SX-6 series vector supercomputer, which is the fastest supercomputer for climate research in Europe.


- Computing with highest performance has successfully been done using a powerful new CRAY XT3TM supercomputer. The complex global Earth System model ECHAM of the MPI-M ran substantially faster, and at higher resolution, than it has ever been run before. Thousands of processors ran the application at a record speed of 1.4 trillion calculations per second (teraflops).

- Optimization and improvement of scalability of the ECHAM model code is done in co-operation with SUN Microsystems using "GRID"-technology. Only such GRID-enabled environments seem to have the potential to deal successfully with the vast amounts of data, which are produced by MPI-M on a routine base and stored in the WDCC.
Earth System and climate science deals with complex phenomena in the atmosphere, the ocean, and on land surfaces, including physical, chemical and biological processes within and feedback-loops between these areas. Modelling such phenomena on extremely powerful computers is a crucial element of Earth System science, since the Earth itself is not available for experiment. Such model simulations would not be possible without strong links into the IT-industry and strong partners such as computer and data centres. Co-operations like these have recently resulted in world record-breaking achievements.

WDCC database

The WDCC database at the DKRZ has an almost inconceivable volume of 220 terabytes and is about twice the size of the database of a well known search engine. The Model and Data Group at the Max Planck Institute for Meteorology (M&D/MPI-M) and the German Climate Computing Centre (DKRZ) operate the WDCC of the International Council for Science. The WDCC’s database contains the latest climate research data on the state of the climate and anticipated climatic changes. 115 terabytes of storage - corresponding to around 24,500 DVDs - are exclusively dedicated to simulation data for the new report of the United Nations’ Intergovernmental Panel on Climate Change (IPCC), which is due to be published in 2007.

High performance with Cray computers

MPI-M estimates that a Cray XT3 would make it possible to complete their next-generation IPCC assessment runs in about the same real time as today, despite requiring 120 times more computation. This advance promises to significantly improve the scale and scope of the analysis researchers will be able to submit for the next assessment report of the IPCC. The newest findings have recently been published (see ).

"GRID"-technology

"GRID"-technology is another field for intense research cooperation. MPI-M provided its ECHAM code to Sun Microsystems to improve optimization and scalability with the Solaris x64 Operating System. Using the Sun Studio Development Tools, Sun benchmarked the code on a "Solarisx64" based cluster. Preliminary runs show a nearly linear scaling on 8 and 16 "SunFire Dual Core Opteron" nodes. In cooperation with MPI-M, Sun intends to continue the optimization of the ECHAM code for much higher numbers of nodes. Equally important for this joint venture between industry and public research is the GRID optimization and adaptation of the data evaluation software environment of MPI-M necessary for advanced Earth System modeling.

Im Focus: Making lightweight construction suitable for series production

More and more automobile companies are focusing on body parts made of carbon fiber reinforced plastics (CFRP). However, manufacturing and repair costs must be further reduced in order to make CFRP more economical in use. Together with the Volkswagen AG and five other partners in the project HolQueSt 3D, the Laser Zentrum Hannover e.V. (LZH) has developed laser processes for the automatic trimming, drilling and repair of three-dimensional components.

Automated manufacturing processes are the basis for ultimately establishing the series production of CFRP components. In the project HolQueSt 3D, the LZH has...

Im Focus: Wonder material? Novel nanotube structure strengthens thin films for flexible electronics

Reflecting the structure of composites found in nature and the ancient world, researchers at the University of Illinois at Urbana-Champaign have synthesized thin carbon nanotube (CNT) textiles that exhibit both high electrical conductivity and a level of toughness that is about fifty times higher than copper films, currently used in electronics.

"The structural robustness of thin metal films has significant importance for the reliable operation of smart skin and flexible electronics including...

Im Focus: Deep inside Galaxy M87

The nearby, giant radio galaxy M87 hosts a supermassive black hole (BH) and is well-known for its bright jet dominating the spectrum over ten orders of magnitude in frequency. Due to its proximity, jet prominence, and the large black hole mass, M87 is the best laboratory for investigating the formation, acceleration, and collimation of relativistic jets. A research team led by Silke Britzen from the Max Planck Institute for Radio Astronomy in Bonn, Germany, has found strong indication for turbulent processes connecting the accretion disk and the jet of that galaxy providing insights into the longstanding problem of the origin of astrophysical jets.

Supermassive black holes form some of the most enigmatic phenomena in astrophysics. Their enormous energy output is supposed to be generated by the...

Im Focus: A Quantum Low Pass for Photons

Physicists in Garching observe novel quantum effect that limits the number of emitted photons.

The probability to find a certain number of photons inside a laser pulse usually corresponds to a classical distribution of independent events, the so-called...

Im Focus: Microprocessors based on a layer of just three atoms

Microprocessors based on atomically thin materials hold the promise of the evolution of traditional processors as well as new applications in the field of flexible electronics. Now, a TU Wien research team led by Thomas Müller has made a breakthrough in this field as part of an ongoing research project.

Two-dimensional materials, or 2D materials for short, are extremely versatile, although – or often more precisely because – they are made up of just one or a...
