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: Neutron star merger directly observed for the first time

University of Maryland researchers contribute to historic detection of gravitational waves and light created by event

On August 17, 2017, at 12:41:04 UTC, scientists made the first direct observation of a merger between two neutron stars--the dense, collapsed cores that remain...

Im Focus: Breaking: the first light from two neutron stars merging

Seven new papers describe the first-ever detection of light from a gravitational wave source. The event, caused by two neutron stars colliding and merging together, was dubbed GW170817 because it sent ripples through space-time that reached Earth on 2017 August 17. Around the world, hundreds of excited astronomers mobilized quickly and were able to observe the event using numerous telescopes, providing a wealth of new data.

Previous detections of gravitational waves have all involved the merger of two black holes, a feat that won the 2017 Nobel Prize in Physics earlier this month....

Im Focus: Smart sensors for efficient processes

Material defects in end products can quickly result in failures in many areas of industry, and have a massive impact on the safe use of their products. This is why, in the field of quality assurance, intelligent, nondestructive sensor systems play a key role. They allow testing components and parts in a rapid and cost-efficient manner without destroying the actual product or changing its surface. Experts from the Fraunhofer IZFP in Saarbrücken will be presenting two exhibits at the Blechexpo in Stuttgart from 7–10 November 2017 that allow fast, reliable, and automated characterization of materials and detection of defects (Hall 5, Booth 5306).

When quality testing uses time-consuming destructive test methods, it can result in enormous costs due to damaging or destroying the products. And given that...

Im Focus: Cold molecules on collision course

Using a new cooling technique MPQ scientists succeed at observing collisions in a dense beam of cold and slow dipolar molecules.

How do chemical reactions proceed at extremely low temperatures? The answer requires the investigation of molecular samples that are cold, dense, and slow at...

Im Focus: Shrinking the proton again!

Scientists from the Max Planck Institute of Quantum Optics, using high precision laser spectroscopy of atomic hydrogen, confirm the surprisingly small value of the proton radius determined from muonic hydrogen.

It was one of the breakthroughs of the year 2010: Laser spectroscopy of muonic hydrogen resulted in a value for the proton charge radius that was significantly...
