Abstract

Summary

We present GeoDRIVE, a software framework tailored to seismic applications embedding high performance features. We discuss the spatial cache-blocking algorithm for the Finite-Difference Time-Domain (FDTD) method and the protocol to find optimal parameters. GeoDRIVE was successfully applied on 3-D large scale seismic surveys using the Shaheen II supercomputer at KAUST. Two applications are presented. In the first one, we successfully produced a 3-D image of the subsurface geologic layers at a record resolution of 7.5 meters with a maximum frequency of 100 Hz ( ). The second application is an elastic modeling using in average 2434 compute nodes in parallel. This achievement represents a workload of 59.6 ExaFLOP on a current PetaFLOP/s machine. This indicates that the next generation of supercomputers targeting the ExaFLOP/s sustained performance, would reduce the running-time of our application to one hour or less. With such performance, it is reasonable to predict that 3D elastic imaging will be a routinely used algorithm by seismic exploration in the next years.
