Hi all,

CERN is in the news again.
Sorry, german only and nothing on LHC@home.

LHC-Grid passes important performance test
The European organization of particle research (CERN) took another important hurdle at the construction of the Grid-Computing-Infrastruktur for scientific performances with the new particle accelerator LHC (Large Hadron Collider). From the CERN-Sitz in Geneva from could over ten days a continuous data flow away big computer centers in Europe (among them the Forschungszentrum Karlsruhe) to sieve on average with 600 MByte/s and the USA upright is held. Altogether, 500 TByte were transferred data during the test time period.

The 27 kilometers long one and barely two billion Euro expensive Hadron-Beschleuniger, from the researcher itself answers to numerous open questions in the physics (approximately after the nature of the so named dark matter) hopes, should go in operation in 2007. One of the biggest scientific rake and storage networks is created parallel to it. Flirted over the big computer centers approximately 6000 scientists from the whole world shall the results of the four planned LHC-Experimente (ALICE) ATLAS, CM, of LHCb later, analyzes.

In the normal operation, the Hadron-Teilchenbeschleuniger should generate more than 1,5 Gbytes data per second. These are set aside redundant in the storage systems of each big computer center, on which approximately 200 involved research institutes have access. End of March, CERN already had tested the new storage infrastructure successfully. The attached research institutes should be able to check among other things with the next tests in the summer, as itself her/its/their Hard, and Software-Equipment with the data transfer for the complex test, and simulation tasks prove.

With the current performance tests, that reflected one third of the future capability of the LHC-Grids approximately, the scientists were very content. The maximum data transfer installments in the high-speed networks of DFN, GARR, GEANT, ESnet, LHCnet, NetherLight, Renater and UKLight would have lain with over 800 MByte/s. "Physicists, who employ itself with particle research, send masses of data around already since long time the world--happened, however, this usually only between two locations up to now and then in relatively short thrusts", the lattice specialist Kors Bos explains. "Meanwhile, however, we are capable to guarantee data transfers between different facilities over days with extremely high transfer installments away. That is the breakthrough
