Best Poster Paper Award Presented at ICCS 2016

Congratulations to NC State Computer Science PhD student Bharathkumar (Tiny) Ramachandra (pictured at right) and Dr. Ranga Raju Vatsavai, associate professor of computer science at NC State, for winning the Best Poster Paper Award at the 16th International Conference on Computational Science held in San Diego, CA, June 6-8, 2016.
The winning paper is “Detecting Extreme Events in Gridded Climate Data” in Procedia Computer Science, Volume 80, 2016, pages 2397-2401.  Co-authors include computer science PhD student Krishna Karthik Gadiraju, and Drs. Dale Patrick Kaiser and Thomas Paul Karnowski of Oak Ridge National Laboratory.  The abstract follows:
Detecting and tracking extreme events in gridded climatological data is a challenging problem on several fronts: algorithms, scalability, and I/O. Successful detection of these events will give climate scientists an alternate view of the behavior of different climatological variables, leading to enhanced scientific understanding of the impacts of events such as heat and cold waves, and on a larger scale, the El Nino Southern Oscillation. Recent advances in computing power and research in data sciences enabled us to look at this problem with a different perspective from what was previously possible. In this paper we present our computationally efficient algorithms for anomalous cluster detection on climate change big data. We provide results on detection and tracking of surface temperature and geopotential height anomalies, a trend analysis, and a study of relationships between the variables. We also identify the limitations of our approaches, future directions for research and alternate approaches.

The International Conference on Computational Science is an annual conference that brings together researchers and scientists from mathematics and computer science as basic computing disciplines, researchers from various application areas who are pioneering computational methods in sciences such as physics, chemistry, life sciences, and engineering, as well as in arts and humanitarian fields, to discuss problems and solutions in the area, to identify new issues, and to shape future directions for research. The theme for ICCS 2016 was "Data through the Computational Lens" to mark the increasing convergence of big data with computational sciences in tackling a myriad of problems and applications. ICCS is an ERA 2010 A-ranked conference series.
