World’s biggest computing grid launched

07.10.2008
The world’s largest computing grid is ready to tackle mankind’s biggest data challenge from the earth’s most powerful accelerator. Today, three weeks after the first particle beams were injected into the Large Hadron Collider (LHC), the Worldwide LHC Computing Grid combines the power of more than 140 computer centers from 33 countries to analyze and manage more than 15 million gigabytes of LHC data every year.

The United States is a vital partner in the development and operation of the WLCG. Fifteen universities and three U.S. Department of Energy (DOE) national laboratories from 11 states contribute their power to the project.

“The U.S. has been an essential partner in the development of the vast distributed computing system that will allow 7,000 scientists around the world to analyze LHC data, complementing its crucial contributions to the construction of the LHC,” said Glen Crawford of the High Energy Physics program in DOE’s Office of Science. DOE and the National Science Foundation support contributions to the LHC and to the computing and networking infrastructures that are an integral part of the project.

U.S. contributions to the Worldwide LHC Computing Grid are coordinated through the Open Science Grid, a national computing infrastructure for science. The Open Science Grid not only contributes computing power for LHC data needs, but also for projects in many other scientific fields including biology, nanotechnology, medicine and climate science.

“Particle physics projects such as the LHC have been a driving force for the development of worldwide computing grids,” said Ed Seidel, director of the National Science Foundation’s Office of Cyberinfrastructure. “The benefits from these grids are now being reaped in areas as diverse as mathematical modeling and drug discovery.”

“Open Science Grid members have put an incredible amount of time and effort in developing a nationwide computing system that is already at work supporting America’s 1,200 LHC physicists and their colleagues from other sciences,” said Open Science Grid Executive Director Ruth Pordes from DOE’s Fermi National Accelerator Laboratory.

Dedicated optical fiber networks distribute LHC data from CERN in Geneva, Switzerland to eleven major “Tier-1” computer centers in Europe, North America and Asia, including those at DOE’s Brookhaven National Laboratory in New York and Fermi National Accelerator Laboratory in Illinois. From these, data is dispatched to more than 140 “Tier-2” centers around the world, including twelve in the United States.

“Our ability to manage data at this scale is the product of several years of intense testing,” said Ian Bird, leader of the Worldwide LHC Computing Grid project. “Today’s result demonstrates the excellent and successful collaboration we have enjoyed with countries all over the world. Without these international partnerships, such an achievement would be impossible.”

“When the LHC starts running at full speed, it will produce enough data to fill about six CDs per second,” said Michael Ernst, director of Brookhaven National Laboratory’s Tier-1 Computing Center. “As the first point of contact for LHC data in the United States, the computing centers at Brookhaven and Fermilab are responsible for storing and distributing a great amount of this data for use by scientists around the country. We’ve spent years ramping up to this point, and now, we’re excited to help uncover some of the numerous secrets nature is still hiding from us.”

Physicists in the U.S. and around the world will sift through the LHC data torrent in search of tiny signals that will lead to discoveries about the nature of the physical universe. Through their distributed computing infrastructures, these physicists also help other scientific researchers increase their use of computing and storage for broader discovery.

“Grid computing allows university research groups at home and abroad to fully participate in the LHC project while fostering positive collaboration across different scientific departments on many campuses,” said Ken Bloom from the University of Nebraska-Lincoln, manager for seven Tier-2 sites in the United States.

U.S. support for LHC participation
The U.S. Department of Energy (DOE) and the National Science Foundation (NSF) invested a total of $531 million in the construction of the Large Hadron Collider and the ATLAS and CMS detectors. DOE provided $200 million for the construction of critical LHC accelerator components, $250 million for the design and construction of the ATLAS and CMS detectors, and continues to support U.S. scientists’ work on the detectors and accelerator R&D. NSF has focused its support on funding university scientists who have contributed to the design and construction of CMS and ATLAS ($81 million). In addition, both agencies promote the development of advanced computing innovations to meet the enormous LHC data challenge. More than 1,700 scientists, engineers, students and technicians from 94 U.S. universities and laboratories (full list available here) participate in the LHC and its experiments.

Im Focus: The pyrenoid is a carbon-fixing liquid droplet

Plants and algae use the enzyme Rubisco to fix carbon dioxide, removing it from the atmosphere and converting it into biomass. Algae have figured out a way to increase the efficiency of carbon fixation. They gather most of their Rubisco into a ball-shaped microcompartment called the pyrenoid, which they flood with a high local concentration of carbon dioxide. A team of scientists at Princeton University, the Carnegie Institution for Science, Stanford University and the Max Plank Institute of Biochemistry have unravelled the mysteries of how the pyrenoid is assembled. These insights can help to engineer crops that remove more carbon dioxide from the atmosphere while producing more food.

Im Focus: Highly precise wiring in the Cerebral Cortex

Our brains house extremely complex neuronal circuits, whose detailed structures are still largely unknown. This is especially true for the so-called cerebral cortex of mammals, where among other things vision, thoughts or spatial orientation are being computed. Here the rules by which nerve cells are connected to each other are only partly understood. A team of scientists around Moritz Helmstaedter at the Frankfiurt Max Planck Institute for Brain Research and Helene Schmidt (Humboldt University in Berlin) have now discovered a surprisingly precise nerve cell connectivity pattern in the part of the cerebral cortex that is responsible for orienting the individual animal or human in space.

The researchers report online in Nature (Schmidt et al., 2017. Axonal synapse sorting in medial entorhinal cortex, DOI: 10.1038/nature24005) that synapses in...

Im Focus: Ultrafast snapshots of relaxing electrons in solids

Using ultrafast flashes of laser and x-ray radiation, scientists at the Max Planck Institute of Quantum Optics (Garching, Germany) took snapshots of the briefest electron motion inside a solid material to date. The electron motion lasted only 750 billionths of the billionth of a second before it fainted, setting a new record of human capability to capture ultrafast processes inside solids!

When x-rays shine onto solid materials or large molecules, an electron is pushed away from its original place near the nucleus of the atom, leaving a hole...

Im Focus: Quantum Sensors Decipher Magnetic Ordering in a New Semiconducting Material

For the first time, physicists have successfully imaged spiral magnetic ordering in a multiferroic material. These materials are considered highly promising candidates for future data storage media. The researchers were able to prove their findings using unique quantum sensors that were developed at Basel University and that can analyze electromagnetic fields on the nanometer scale. The results – obtained by scientists from the University of Basel’s Department of Physics, the Swiss Nanoscience Institute, the University of Montpellier and several laboratories from University Paris-Saclay – were recently published in the journal Nature.

Multiferroics are materials that simultaneously react to electric and magnetic fields. These two properties are rarely found together, and their combined...
