Innovative search for world’s biggest physics laboratory

Huge quantities of data from the particle accelerator experiment at the CERN Research Center converge in Karlsruhe. They are saved and processed in a worldwide networked grid computing centre. The Global Grid User Support at the Research Center in Karlsruhe relies on the ConWeaver search engine technology developed at the Fraunhofer IGD for project-related information management.

The Research Center in Karlsruhe is one of the biggest research institutions for natural and engineering scientists in Europe. Every day thousands of scientists all over the world access the data saved in the computing centre. Since the beginning of September 2008 there is even more data converging in Karlsruhe. Here is one of the main hubs through which the data for the large-scale experiment with the particle accelerator at the European Research Center (CERN) in Geneva passes.

The experiments of the Large Hadron Collider at CERN generate huge quantities of data. Experts estimate up to several gigabytes per second for individual experiments. In order to be able to analyze this effectively, scientists have built a worldwide grid infrastructure. This includes eleven Regional Operating Centers (ROCs) each with thousands of networked computers in locations including Germany, Taiwan and the USA. As one of the ROCs the Research Center in Karlsruhe provides computing and memory capacity and looks after the coordination of the worldwide grid user support.

The teams of the ROCs provide first-level support on a weekly rotation. They do not get to know the teams personally and the time differences of the different locations make their work more difficult. A helpdesk employee in Karlsruhe does not know about the queries that a colleague dealt with in Taipeh the week before.

The “Global Grid User Support” (GGUS) project tackles these problems and focuses on intelligent information-technological solutions. GGUS integrates a search engine that doesn’t only find best-practices and solutions to problems, but also suggests independent solutions and best practices for the given problem.

The search and suggestion function is based on the ConWeaver-technology of the Fraunhofer spin-off ConWeaver GmbH. It was especially adapted for the GGUS by the GGUS team together with ConWeaver employees from the Fraunhofer IGD. “Such innovative information technological solutions are a suitable tool for the large challenge faced by the helpdesk,” explains Rainer Kupsch, who at the time was Department Manager of the Research Center in Karlsruhe. “By improving the productivity of the support employees and the quality of the answers, the grid-relevant problems can be solved more quickly,” says Dr. Antoni, Group Manager at GGUS.

The ConWeaver team is presenting its technology at the 4th Semantics Day “User Workshop – Semantics Search with ConWeaver” on November 12, 2008 in Darmstadt. Further information can be obtained from:

Im Focus: New 3-D wiring technique brings scalable quantum computers closer to reality

Researchers from the Institute for Quantum Computing (IQC) at the University of Waterloo led the development of a new extensible wiring technique capable of controlling superconducting quantum bits, representing a significant step towards to the realization of a scalable quantum computer.

"The quantum socket is a wiring method that uses three-dimensional wires based on spring-loaded pins to address individual qubits," said Jeremy Béjanin, a PhD...

Im Focus: Scientists develop a semiconductor nanocomposite material that moves in response to light

In a paper in Scientific Reports, a research team at Worcester Polytechnic Institute describes a novel light-activated phenomenon that could become the basis for applications as diverse as microscopic robotic grippers and more efficient solar cells.

A research team at Worcester Polytechnic Institute (WPI) has developed a revolutionary, light-activated semiconductor nanocomposite material that can be used...

Im Focus: Diamonds aren't forever: Sandia, Harvard team create first quantum computer bridge

By forcefully embedding two silicon atoms in a diamond matrix, Sandia researchers have demonstrated for the first time on a single chip all the components needed to create a quantum bridge to link quantum computers together.

"People have already built small quantum computers," says Sandia researcher Ryan Camacho. "Maybe the first useful one won't be a single giant quantum computer...

Im Focus: New Products - Highlights of COMPAMED 2016

COMPAMED has become the leading international marketplace for suppliers of medical manufacturing. The trade fair, which takes place every November and is co-located to MEDICA in Dusseldorf, has been steadily growing over the past years and shows that medical technology remains a rapidly growing market.

In 2016, the joint pavilion by the IVAM Microtechnology Network, the Product Market “High-tech for Medical Devices”, will be located in Hall 8a again and will...

Im Focus: Ultra-thin ferroelectric material for next-generation electronics

'Ferroelectric' materials can switch between different states of electrical polarization in response to an external electric field. This flexibility means they show promise for many applications, for example in electronic devices and computer memory. Current ferroelectric materials are highly valued for their thermal and chemical stability and rapid electro-mechanical responses, but creating a material that is scalable down to the tiny sizes needed for technologies like silicon-based semiconductors (Si-based CMOS) has proven challenging.

Now, Hiroshi Funakubo and co-workers at the Tokyo Institute of Technology, in collaboration with researchers across Japan, have conducted experiments to...
