Abstract

Earthquakes, Tsunamis, the Ionosphere and Computer Science

Tsunami detection and forecasting is a difficult problem that scientists are trying to tackle. Early estimation and accurate prediction of the arrival time and size of a tsunami can save lives and help with impact assessment. Tsunami inducing earthquakes cause ground and sea-surface displacements that push on the atmosphere and propagate into the ionosphere. IonoSeis is a software simulation package that leverages satellite-based ionospheric remote-sensing techniques to determine the epicenter of these earthquakes. The execution time of the ray-tracing component of IonoSeis prevents its use as a real-time modelling tool. A proposed solution is to replace this component with a newer ray-tracing package developed by Los Alamos National Lab called GeoAc and optimize it. This research is a case study that aims to determine how much improvement stands to be gained by using the polyhedral framework and dataflow graphs to parallelize and optimize the operational GeoAc code.

Biography

Ravi earned his bachelor’s degree in computer science with a minor in applied mathematics. He is currently a master’s student studying computer science. Ravi is a member of the Application Data flow optimizations with Programming languages and Transformations (ADaPT) lab and his research focuses on performance optimization. He was the lead developer on a lidar data processing project and presented a paper on his work at the 15th international conference on eScience in 2019. Ravi is currently working on a case study to parallelize scientific applications using polyhedral dataflow graphs. Ravi enjoys traveling and experiencing new cultures and environments. When he’s not working on his thesis, you can find him reading or learning to play the guitar.
