One billion events of this type, the simulated response to the same ultra-high-energy muon neutrino event in the AMANDA-B10 detector and the future IceCube array, were produced at Swegrid, the Swedish Grid facility.

The Art of Monitoring with MonALISA

Operating a successful grid, network or computing facility requires vast amounts of monitoring information. Projects and organizations worldwide that need to track resource usage, network traffic, job distribution and many other quantities rely on Caltech's MonALISA system to collect the information and present it in a way that allows them to make effective decisions. The system also automatically troubleshoots and optimizes very large grid and network systems.

"While developing computing models for experiments at the Large Hadron Collider, we realized that vital monitoring information was missing," explained Caltech's Iosif Legrand, MonALISA's chief architect. "We didn't want to reinvent the wheel, so we built a framework that collects and synthesizes data from many existing monitoring tools and built new tools only where needed."

MonALISA, which stands for Monitoring Agents Using a Large Integrated Services Architecture, has been developed by Caltech and its partners over the last five years. The framework monitors everything from single computers to large facilities and global networks. At CERN in Geneva, Switzerland, MonALISA services monitor 2,500 computers and transcontinental and intercontinental network links. The Open Science Grid uses the framework for resource and network monitoring, and the GLORIAD network monitors traffic and all major routers using MonALISA.

EGEE Battles Malaria With Grid Wisdom

The first biomedical data challenge for drug discovery ran successfully this summer on the EGEE grid production service. Entitled WISDOM (Wide In Silico Docking on Malaria), the challenge used 1,000 computers in 15 countries simultaneously, resulting in over 46 million docked ligands. This type of scientific challenge would not be possible without the EGEE grid infrastructure, as in silico docking usually produces only around 100,000 docked ligands when carried out on classical computer clusters.

In silico docking enables researchers to compute the probability that potential drugs will dock with a target protein. This very promising approach may speed up and reduce the cost to develop new drugs to treat diseases such as malaria. The data challenge is a step towards realizing a full in silico drug discovery platform that would use a docking approach to propose new inhibitors for the target proteins implicated in malaria.

NSF proposes next-generation Internet
Network World, August 29, 2005
By Grant Gross

The National Science Foundation has proposed a next-generation Internet with built-in security and functionality that connects all kinds of devices, with researchers challenging the government agency to look at the Internet as a "clean slate."
