Massively Parallel Earthquake Simulations on GPUs
This presentation describes an R&D effort sponsored by NASA’s Earth Sciences Division, that involves GPU implementation of a topologically-realistic numerical simulation of earthquakes occurring on the fault systems of California. The computationally intensive modules include (i) Generation of a large-scale stress influence matrix (Green’s functions) from fault element data, and (ii) Calculation of stress from the strain vector using large-scale matrix vector multiply, during the rupture propagation phase. Identification of the computational bottlenecks, CUDA code implementation and various code optimizations that led to a 45× speedup over a multi-core CPU implementation, for a 30,000-year earthquake simulation, will be discussed.
Dr. Monish Tandale earned his MS and PhD in Aerospace Engineering at Texas A&M University. Currently he is a Senior Research Scientist at Optimal Synthesis Inc. where he leads GPU Computing R&D projects supported by NASA and the Department of Defense. These R&D projects have accelerated many computationally intensive algorithms in diverse domains such as aircraft trajectory prediction, numerical optimization for air-traffic management, Monte Carlo simulation, particle filter tracking for ballistic missile interception, financial market forecasting and earthquake simulation. His GPU computing research received recognition on NVIDIA’s CUDA Spotlight and was selected as one of the highlights of GTC 2010.
