This map shows sites participating in Nordic grid projects or using middleware developed
by the NorduGrid project. Since the beginning of the European Data Grid project, Nordic countries
have participated in international grid projects and have worked to form their own projects and
develop their own middleware. Read more about grid projects in the Nordic countries in the September CERN Courier.

provided through the EU's sixth Research Framework Programme,
will be distributed among 23 new research projects.

Solving the Football
Pool Problem

Grids are being used to help solve one of the most famous problems in mathematical coding theory.
The football pool problem gets its name from a lottery-type game in which participants predict the outcome of soccer matches. The current challenge is to find the minimum number of lottery tickets a person would have to buy to guarantee that for six matches, no more than one prediction (out of 729 possible outcomes) is wrong. In the language of mathematical coding theory, that translates to determining the smallest covering code of ternary words of length six.
Jeff Linderoth of Lehigh University, Francois Margot from Carnegie Mellon University and Greg Thain from the University of Wisconsin-Madison have developed a mathematical application to search for a solution to the football pool problem. The application was initially adapted to run on the Grid Laboratory of Wisconsin, the University of Wisconsin-Madison’s campus grid. In the spring of 2006, Dan Bradley of DISUN, the Data Intensive Science University Network, developed services to route GLOW jobs to Open Science Grid sites.
After decades of study, researchers had only been able to reduce the minimum number of tickets to between 65 and 73. In five months using GLOW and OSG resources in combination with computing resources from DISUN and the TeraGrid, over 90 CPU years have been spent to establish that the answer must be between 70 and 73.

DIANE Creates Efficient Scheduling on the Grid

A tool for parallel scientific applications, the Distributed Analysis Environment (DIANE),
has been successfully used in several processing challenges on the Grid. In April, DIANE was
used during the in silico drug-discovery application to analyse possible drug components to
fight the avian flu virus on the Enabling Grids for E-sciencE (EGEE) infrastructure.
In the following months, the DIANE scheduling layer was also
used for a series of large-scale data-processing tasks for the International
Telecommunications Union using several grid sites around Europe.
Originally targeted at investigating distributed analysis
for particle physics, DIANE has become an application-independent user-scheduling tool
on the Grid and has been interfaced with a number of applications in various fields.
