European and American supercomputing infrastructures linked through a common wide-area global file system

07.12.2005


DEISA, the European supercomputing grid infrastructure, and TeraGrid, the US supercomputing cyberinfrastructure, and have been linked, for the purposes of a technology demonstration, by a common, scalable, wide-area global file system spanning two continents.



The bridging of communities in the old and the new world were showcased during the Supercomputing Conference SC05 at Seattle. It was shown that any scientist, accessing TeraGrid from any of the participating sites in the US, or accessing DEISA from any of the DEISA sites in France, Germany or Italy, can directly and transparently create or access collaborative data stored in the now linked grid-wide global file systems of TeraGrid and DEISA with one common file address space. The even more important aspect is that the same is true for applications which, executed at any of the participating sites, transparently access data in the common file address space.

High performance wide-area global file systems as GPFS from IBM open totally new modes of operation within grid infrastructures, especially in supercomputing grids with a fairly limited number of participating sites. A common data repository with fast access, transparently accessible both by applications running anywhere in the grid, and by scientists working at any partner site as entry point to the grid, greatly facilitates cooperative scientific work at the continually increasing geographically distributed scientific communities.


Both DEISA and TeraGrid have begun using the high performance wide-area global file system GPFS from IBM in production mode. For the technology demonstration, the dedicated DEISA and TeraGrid networks were interconnected with the help of specialists from GEANT, Abilene/Internet2, and the national research networks from France, Germany, and Italy (RENATER, DFN, GARR). They established a two continent spanning high performance network between TeraGrid sites at The San Diego Supercomputer Center (SDSC), Chicago, and Indiana, and DEISA sites in several European countries (France, Germany, Italy). Over this dedicated connection, DEISA and TeraGrid global file systems were merged into one common global file system. This network connection between the two infrastructures is expected to become persistent at some time in the future.

The demonstration featured the execution of supercomputing applications of various scientific disciplines which were carried out both as TeraGrid and as DEISA applications. Single site applications transparently wrote their results to the intercontinental global file system, ready for transparent further processing from other access grid access points.

Featured applications for the demo included a Protein Structure Prediction and a Cosmological Simulation carried out at SDSC, US (www.sdsc.edu) and a Gyrokinetic Turbulence Simulation and also a Cosmological Simulation carried out at Garching Computing Centre of the Max Planck Society (RZG), Germany.

Im Focus: Dresdner scientists print tomorrow’s world

The Fraunhofer IWS Dresden and Technische Universität Dresden inaugurated their jointly operated Center for Additive Manufacturing Dresden (AMCD) with a festive ceremony on February 7, 2017. Scientists from various disciplines perform research on materials, additive manufacturing processes and innovative technologies, which build up components in a layer by layer process. This technology opens up new horizons for component design and combinations of functions. For example during fabrication, electrical conductors and sensors are already able to be additively manufactured into components. They provide information about stress conditions of a product during operation.

The 3D-printing technology, or additive manufacturing as it is often called, has long made the step out of scientific research laboratories into industrial...

Im Focus: Three Magnetic States for Each Hole

Nanometer-scale magnetic perforated grids could create new possibilities for computing. Together with international colleagues, scientists from the Helmholtz Zentrum Dresden-Rossendorf (HZDR) have shown how a cobalt grid can be reliably programmed at room temperature. In addition they discovered that for every hole ("antidot") three magnetic states can be configured. The results have been published in the journal "Scientific Reports".

Physicist Dr. Rantej Bali from the HZDR, together with scientists from Singapore and Australia, designed a special grid structure in a thin layer of cobalt in...
