Simulating Earthquake Faults (FESD)
HPGeoC Researchers are assisting researchers from six other universities and the US Geological Survey (USGS) to develop detailed, large-scale computer simulations of earthquake faults under a new $4.6 million National Science Foundation (NSF) grant announced September 2011. The initial focus is on the North Americn plate boundary and the San Andreas system of Northern and Southern California.
GPU Acceleration Project
HPGeoC has developed a hybrid CUDA+MPI paradigm with AWP-ODC code that achieved 2.3 Pflop/s sustained performance and enabled a rough fault 0-10Hz modeling simulation on ORNL Titan. This code is also used to study the effects of nonlinearity on surface waves during large quakes on the San Anderas fault.
