European supercomputing network ready to go

With fiberglass floor, for which traffic information to tens of gigabytes per second allow researchers to remotely expects huge barges to carry DEISA.

Until a few years ago shot the super computing power of many computers short of excellence in areas such as quantum mechanics. After more than four years' work has now come to an end thanks to the Distributed European Infrastructure for Supercomputing Applications (DEISA), a network of a dozen of the most powerful supercomputers in Europe.

Herman Lederer, head of external relations in DEISA, says in a press release that "The multinational communication formerly ran extremely difficult because each individual supercomputer had access methods. Now a scientist in Italy a supercomputer in the Netherlands on a simple and fast way. "

DEISA is one of the two most powerful supercomputing networks in the world. The other network, TERAGRID is located in the United States.

The first step in the construction of DEISA was to create a fast network for data between computers. This network consists of fiber optic cables that are capable of up to 10 gigabytes of data per second to transport. Moreover, DEISA designed for data streams simultaneously through different to send what the whole faster.

The network also provides a safe working environment for the computers. "All the super computers are reliable hosts. The security is as high as super-computers would be used for illegal purposes such as developing nuclear weapons. "Lederer says.

The super-fast network, the IT specialists DEISA also a global file system to be set for users who log in from any part in DEISA. When a user logs on to a supercomputer, then activates a folder with personal data. This folder is always available to users, wherever they log on. "It is perfectly possible that your data in your map stops moving physically in another country," explains Lederer off. "This also makes it easier for scientists to work together. Their data are always available, from Finland to Italy. "

'The purpose', says Lederer, "was to provide users with the same interface and computing environment for all DIESA super computers, whether they log on to one of the DEISA supercomputing centers in the network or via their own laptop."

Since we started to build DEISA, the maximum computing power transmitted by a factor of 300 from 30 teraflops (30,000 one billion calculations per second) to one petaflop (one million times one billion calculations).

And by 2010 there were between three to five-petaflop supercomputers installed in Europe, according to Lederer. "The infrastructure is already there: it was designed, built and installed by DEISA. Everything is ready for the new super computers in the network. "(CVE)
