Feature - Identifying network bottlenecks Internet2 and the Open Science Grid have formed a partnership to deploy advanced network monitoring and diagnostic tools on the grid. Image courtesy of invoice-factoring.com.au. Network performance problems bedevil scientists and network operators alike.  Troubleshooting requires a multi-pronged approach, and problem resolution often drags – holding back scientific progress. To address this in the grid community, Internet2, the leading U.S. networking consortium in the research and education community, has formed a partnership with the Open Science Grid to deploy a set of advanced network monitoring and diagnostic tools on the grid.Network users and operators solve problems most quickly when given transparent access to the entire network path involved. Typically, however, separate organizations operate different segments along a full network path and each so-called “domain” controls access to its own diagnostic and p

Feature - Grid sails to the aid of shipbuilding

Feature - Grid sails to the aid of shipbuilding New FSG ships anchored next to the factory building where they were constructed. Image courtesy of FSG Shipyards in Europe cannot compete on price alone against overseas competitors, especially those based in the Far East.Consequently, European shipbuilders must  concentrate on high-quality construction projects that are specially tailored to their customer's requirements. Each ship is a unique product, produced only once or in a very small run. To improve their competitive position, modern European shipyards must harness the most advanced simulation and design tools to produce complex structures cost effectively, in order to reduce the technical and economic risks at a time when orders for new ships are down worldwide.The goal? The complete, virtual design of a ship. The solution: the grid. At the Flensburger Schiffbau Gesellschaft (FSG) shipyard, managers wanted to find ways to design their ships so that they used less of costly materials such as steel — while r

Keeping track of huge job sets processed on hundreds of compute clusters around the world through the LHC Computing Grid might send the most organized of logical thinkers into a tizzy. The PanDA (Production and Distributed Analysis) system, developed for the ATLAS collaboration at the Large Hadron Collider, lets scientists stay cool while it takes charge of distributing jobs, collecting results and managing workflow.An important feature of PanDA is that it allows the user to submit one job, called a pilot job, which coordinates a series of jobs that the user has put together and configured. When launched, the pilot job contacts the PanDA server, which in turn locates available resources and sends the collected jobs to run based on their relative priorities. The pilot system manages the workflow efficiently,

Feature - Help create an earthbound sun A view of the International Thermonuclear Experimental Reactor (ITER), showing its main components, with a person for size reference. One of the pilot applications running in Ibercivis is devoted to ITER simulations. Image courtesy of ITER The dream of fusion power sounds so fantastic that one’s initial reaction might be to dismiss it as science fiction. Yet  scientists hope to bring the power that emblazons the sun, fusion, to earthbound reactors. In this type of reaction two atomic nuclei bind — or fuse — together to form a heavier atom, triggering a monumental release of energy. The International Thermonuclear Experimental Reactor (ITER) is a joint international research and development project seeking to build a prototype fusion power plant. (The finished machine will be located in the south of France.) Aiding ITER in its computational load is Ibercivis, a volunteer computing project centered in Spain, which allows computer users citizens to donate unused computing

Feature - The magic of GENI: Building networks for the future It may look like a galaxy, but is actually a map of the Internet, showing the hardware that serves as its 'skeleton' or infrastructure of the Internet. Colors indicate geographic location. Despite its obvious complexity, this map represents just a fraction of the whole network - the rest is simply impossible to accurately represent. Image courtesy of Barrett Lyon, The Opte Project The Internet may be a powerful tool. But researchers trying to extend the Net's capabilities want to test their ideas for improving network design, distributed systems and cyber-security without disrupting or breaking it.  Recognizing this, the National Science Foundation started the Global Environment for Network Innovations (GENI) project. GENI will provide an infrastructure for a large-scale experimental network, where researcher can build test versions of the Net to safely study networking in ways never before possible.Some of those participating in the first phase of th

Observing the grid Peer through Grid Observatory to explore the world of the grid.  Image copyright © 2005-2008 David Opie What was once lost has now been found—and stored.Thanks to the Grid Observatory, people in the esoteric field of studying the behavior of large, distributed systems have been given a gift: a trove of data. Like astronomers who peer through a telescope to explore the solar system, researchers in grids and complex systems are able to examine Grid Observatory’s data repository to find new patterns in the global behavior of the grid. The Grid Observatory, a sub-set of Enabling Grids for E-sciencE’s applications group, opened its doors—via a Web portal—this autumn. Through the portal, researchers can access anonymous grid traces, collected and stored through the Grid Observatory application, and information about those traces, for an overall picture of the grid. Grid traces, explains Cécile Germain of Grid Observatory, are signatures of grid usage. These take many f

Feature - Zero-carbon data centers for green computing “There are a number of companies (and universities) deploying zero carbon data centers in Canada and USA,” says St. Arnaud. “These data centers are solely powered by renewable resources.”   Canadian sites—powered by water and wind—are shown here along with leased wavelength connections (red) and networks (blue and grey).Image courtesy of CANARIE. Information and communication technology (ICT), the fifth largest consumer of power in the world, currently contributes 3-4% of the world’s CO2 emissions—and is doubling every three to four years. To reduce its carbon footprint, the ICT industry has started relocating computing facilities to zero-carbon data centers at renewable energy sites.Most of the energy used for ICT is supplied by coal, which is very dirty, explains Bill St. Arnaud of the Canadian Advanced Network and Research for Industry and Education (CANARIE). In a year, one medium sized server generates as much CO2

Feature - ORIENT grid project supports Chinese earthquake aid work The idea behind the sending of high-definition image of China's earthquake damage on the ORIENT grid can be traced to the transmission of radio-telescope data from the Shanghai Astronomical Observatory to Europe. Image courtesy of GÉANT2 When a major earthquake struck Sichuan, China last May, rescue workers urgently needed high-resolution satellite images of the affected areas in order to identify the extent of the earthquake’s devastation and aid in post-disaster relief. They also wanted the information to help protect the area from further risk during rebuilding efforts.To do so, the Chinese Ministry of Science and Technology turned to the European Commission’s Joint Research Centre (JRC) for a key item to analysis and reconstruction: The ORIENT project’s high-capacity data communication route. Normally used to link research and education networks between China and Europe for things such as high speed transmission of astronomical d

  Feature - Europe and China working together to optimize network layer The EC-GIN team, pictured here at a July 2007 conference in Greece, are working to develop tailored network technology in dedicated support of grid applications. Image courtesy of EC-GINThe Internet communication infrastructure—the TCP/IP protocol stack—is designed for broad use and as such does not account for the specific characteristics of grid applications.This one-size-fits-all approach works for a number of application domains; however, it is far from optimal and is not as efficient as customized solutions. While grid technologies and services are slowly coming of age, the corresponding network infrastructure is still in its infancy. In an effort to change this, Europe and China are working together to improve the network’s ability to support grid applications and services. Called the Europe-China Grid InterNetworking project, or EC-GIN, the project aims at developing a tailored network technology in dedicated support of grid appl
