Images of the week - CERN Open Day draws tens of thousands

The GridCafé provided a friendly spot for visitors to learn about grid technology, discover the history of computing at CERN, take the challenge of grid-themed computer games, explore interactive grid maps, hot coffees, cakes and more.

GridCafé volunteers answered the big questions for visitors from all over the world, explaining the difference between grid technology and the Internet and sharing the different ways in which grid technology is helping to fast-track scientific research.

Volunteers showcased emerging technologies including GridMap (CERN openlab/EDS), a visualization that shows the status of different sites in the Worldwide Large Hadron Collider Computing Grid. Green indicates the site is "OK," orange indicates degraded service and red indicates that the site is down.

The CERN Computer Centre, just prior to opening its doors. Over the two days, 5 and 6 April 2008, CERN welcomed more than 70,000 visitors to tour "behind the scenes." The computer center, staffed by teams of volunteer guides, saw a constant stream of visitors.

The CERN Computer Centre currently comprises around 4500 machines with 16,000 processing cores; an extra 12,000 cores will be added during 2008. The center is Tier 0 in the Worldwide Large Hadron Collider Computing Grid, connecting Tier 1 centers using dedicated 10 Gigabit per second links.

More than 30,000 visitors "went underground" over the two days, taking advantage of an increasingly rare chance to see inside the Large Hadron Collider tunnels and see its experiments in place in their underground caverns. Other activities included exhibitions, films, live shows, demonstrations and experiments.
