The U.S. Department of Energy, Office of Science, Office of Basic Energy Sciences and Office of Advanced Scientific Computing Research will hold the 2011 ASCR/BES Data Workshop at the Bethesda North Marriott Hotel & Conference Center in Bethesda, MD. The meeting will begin on Monday, October 24 and conclude on Tuesday, October 25, 2011. The goal of this workshop is to identify current and anticipated issues in the acquisition, analysis, communication and storage of experimental data that could impact the progress of scientific discovery. Research at Basic Energy Sciences (BES) user facilities and in other BES-supported programs is producing unprecedented volumes of data which must be managed and analyzed for maximum scientific impact. Scientists and engineers supported by programs in the Advanced Scientific Computing Research Office have pioneered solutions for managing, communicating and analyzing large data sets resulting from advanced simulations using leadership-class computational facilities. Combining the expertise of these communities offers significant benefits through identifying new solutions for data challenges. Paths forward to address identified issues will be outlined based on expected advances in the state of the art in systems, algorithms and processes on the critical path for extracting discoveries from data. A primary benefit from the workshop will be in identifying critical steps to maximize scientific impact made possible by the coordinated, optimized use of the resources available through major national investments in facilities for experimental, computational and theoretical science.
