DoE Supports Samatova’s Research on AMR

Dr. Nagiza Samatova, professor of computer science at NC State University, has been awarded $383,000 by the US Department of Energy (DoE) to support her research proposal entitled “In Situ Indexing and Query Processing of AMR Data.”
The award will run from September 1, 2014 to August 31, 2017. 
Abstract –One of the most significant advances for large-scale scientific simulations has been the advent of Adaptive Mesh Refinement, or AMR. By using dynamic gridding, AMR can achieve substantial savings in memory, computation, and disk resources while maintaining or even increasing simulation accuracy, relative to static, uniform gridding. However, the resultant non-uniform structure of the simulation mesh produced by AMR methods cause inefficient access patterns during data analysis and visualization. Given the exponential increase in simulation output, the massive I/O operations are becoming a substantial bottleneck in simulations and analysis. To efficiently analyze AMR data, we propose an integrated, three-prong approach that aims: (a) To devise an AMR query model; (b) To develop effective in situ indexing and query processing methods for AMR data analytics; and (c) To investigate data storage layout strategies for AMR data retrieval optimized for analytics-induced heterogeneous data access patterns. The results, algorithms, and software will be in the public domain.
