Keynote Presentation
    Title: Scientific Data Services Framework for Exascale Infrastructure (slides)
    Abstract: Scientific facilities, including light sources, electronic microscopes, and high-energy colliders produce a vast amounts of data. Thousands of different analysis tasks are performed on these datasets to generate scientific insight. Often I/O operations are the bottleneck in these analysis operations. This work address the I/O efficiency issue by developing techniques for common data access patterns, for deep storage hierarchies, and for massive parallelism. Additionally, we present a thorough theoretical analysis of the data access cost to exploit the structural locality, and select the best array partitioning strategy for a given operation. In a series of performance tests on large scientific datasets, we have observed that our framework outperforms Spark by as much as 2070X on the same tasks.

    Dr. John Wu is a Senior Computer Scientist at Lawrence Berkeley National Laboratory. He works actively on a number of topics in data management, data analysis, and high-performance computing.  His algorithmic research work includes statistical methods for feature extraction, indexing techniques for searching large datasets, and matrix based techniques for machine learning and scientific computing. He has authored and coauthored more than 100 technical publications, 11 of which have more than 100 citations each. He is the developer of a number of software packages, including, IDEALEM, SDS, FastBit and TRLan.  Among them, the FastBit software for indexing large datasets has earned an R&D 100 Award, and is used by many organizations.  For example, a German bioinformatics company uses FastBit to accelerate their molecular docking software by hundreds of times, and an US internet company uses it to sift through terabytes of advertisement related data daily.  A FastBit paper is collected among the 40 major works funded by DOE Office of Science, as a part of its 40th Anniversary celebration.
