Title:

Scientific Data Mining: Challenges at the Petascale

Abstract:

The data from scientific simulations, observations, and experiments is now being measured in terabytes and will soon reach the petabyte regime. The size of the data, as well as its complexity, make it difficult to find useful information in the data. This is of course disconcerting to scientists who wonder about the science still undiscovered in the data. The Sapphire scientific data mining project at Lawrence Livermore National Laboratory (https://computation.llnl.gov/casc/sapphire) has been addressing this concern by applying data mining techniques to problems ranging in size from a few megabytes to a hundred terabytes in a variety of domains. Using example problems from astronomy, fluid mixing, remote sensing, and experimental physics, I will describe our solution approaches and discuss some of the challenges we have encountered in mining these datasets.
