Phani Nukala and Robert Harrison of Oak Ridge National Laboratory are among some three dozen researchers who will be presenting invited talks at the 2006 Scientific Discovery through Advanced Computing Program June 25-30 in Denver. Three hundred researchers are expected to attend the event, being hailed by organizers as a celebration of computational science worldwide. Highlights of the conference include presentations by the Department of Energy's Raymond Orbach and Michael Strayer, who will also announce projects to be funded by SciDAC this year. SciDAC was founded by DOE in 2001 to bring together physical scientists, mathematicians and computer scientists from different institutions. Accomplishments under SciDAC are varied and include gaining a better understanding of the origins of the universe, predicting with greater certainty global climate change and devising ways to burn fuels more cleanly and efficiently.
