"We're using the grid to process three years' worth of data — one billion particle collisions — in six months," said Fermilab guest scientist Daniel Wicke, on leave from the University of Wuppertal, Germany, who heads the reprocessing effort. "DZero has a long history of using computing resources from outside Fermilab, including a project in 2003 to send a much smaller amount of data off-site for reprocessing. We knew that this much bigger effort, remotely processing ten times more collisions than before using five times the number of computers, would be possible."

As new data is recorded with the DZero detector at the Tevatron, the world's highest-energy particle accelerator located in Batavia, IL, it is processed into a form useable by physicists. The cluster of one thousand computer processors dedicated to DZero computing at Fermilab is kept busy processing the newly acquired data.

Jack Upton

Upton grew up about 30 miles north of Fermilab, on what is now the Crab Tree Nature Center. He also served in the Strategic Air Command before working at Argonne. He is unsure of what he will do during his retirement. "Oh, I don't know, maybe clean up my house," said Upton. "I haven't thought about it. Time goes fast when you are having fun."

Upton's supervisor Eileen Hahn had only positive comments about him. "We joke about his name because he really is a jack-of-all-trades," said Hahn. "He is one of the sweetest guys ever. He is very creative, always a great help, understands the big picture and how it all fits together. We will sorely miss him."

There will be a retirement party for Upton next Friday, May 6th, at 11:30 at Le Berry Bistro in Geneva. If you would like to attend, please contact Eileen Hahn at x4164 or Sabina Aponte at x3651 by May 3.
