IBM and TRIUMF, Canada's national laboratory for particle and nuclear physics, announced that the ATLAS Tier-1 Data Analysis Center -- dedicated to investigating the fundamental structure of matter -- is ready for production after a significant hardware upgrade. The upgrade increases the computing power and the disk storage by a factor of about seven and adds a tape silo to store the raw data from ATLAS. The Tier-1 center is now one of the most powerful computing facilities in Canada.

The new IBM System Cluster 1350 supercomputer incorporates IBM's newly announced DCS9550 Disk Storage System. After passing extensive acceptance tests, the system has been integrated into an international grid of high-performance computing centers that will analyze data from the global ATLAS project, commencing in the summer of 2008.

A team of researchers from a consortium of 10 Canadian universities and TRIUMF are participating in the ATLAS experiment in Geneva. ATLAS will study proton-proton collisions at the highest energy ever achieved in the laboratory and will search for the elusive Higgs particle. The Higgs boson is an essential ingredient in the theory of how the mass of subatomic particles is generated.

The conditions created in the high-energy collisions will be similar to those that existed during the Big Bang. To accomplish this, the European Center for Nuclear Research (CERN) is building the world's largest particle collider, the LHC, which has a circumference of 27 kilometers.

The Canadian team will use the supercomputer, located at TRIUMF in Vancouver, to analyze information churned out by the ATLAS experiment, estimated to be equivalent to half a million DVDs worth of data every year for as long as the experiment will run. TRIUMF's IBM System Cluster 1350 was specially designed to handle the large amounts of data processing required by the CERN experiments.

The Tier-1 data center was funded by grants to the consortium universities from the Canada Foundation for Innovation, and the British Columbia Knowledge Development Fund, as well as a contribution by IBM.

"We are extremely pleased to have the first phase of the data analysis centre complete," said Michel Vetterli, a professor of physics at Simon Fraser University and TRIUMF, who is the leader of the Tier-1 project. "The system has performed very well during full-scale tests where it was incorporated into the Worldwide LHC Computing Grid. The ground-breaking discoveries enabled by the Tier-1 will revolutionize the way we describe the universe at the most fundamental scale."

"The CERN ATLAS experiment will push the boundaries of computational processing and data storage beyond anything the world has seen before," said Chris Pratt, strategic initiatives executive for IBM Canada. "IBM's technology and expertise is an integral part of enabling the next generation of global scientific exploration right here in Canada."
