Seismic imaging aims at providing accurate and detailed 3D maps of the earth subsurface from acoustic wave propagation recording at the surface. Today's seismic imaging algorithms are rather crude compared to what this industry would do if given access to Exascale systems. CGGVeritas applications portfolio and geophysical research activities provide samples of seismic imaging codes representative of current and future trends of the oil and gas industry. From a programming perspective, those codes are both very compute and I/O intensive, but are most of the times featuring enough intrinsic parallelism to make them good candidates for large scale parallelisation.
The DEEP Architecture will allow us to study the level of scalability of our key applications by re-engineering the codes to take advantage of the vector capabilities of the Booster Nodes, while relying on the Cluster Nodes to address the lack of locality of these algorithms by exchanging data during the computations.
These simulations are done by CGGVeritas, France.
