Webinar: Accelerating FWI via OpenCL on AMD GPUs

Join Chris Mason, Acceleware Product Manager, as he presents a case study of accelerating a seismic algorithm on a cluster of AMD GPU compute nodes, for geophysical software provider and processor GeoTomo. The presentation will begin with an outline of the full waveform inversion (FWI) algorithm, followed by an introduction to OpenCL. The OpenCL programming model and memory spaces will be introduced. After a short programming example, Chris takes you step-by-step through the project phases of profiling, feasibility analysis and implementation. Chris shares the strategy for formulating the problem to take advantage of the massively parallel GPU architecture. Key optimizations techniques are discussed including coalescing and an iterative approach to handle the slices. Performance results for the GPU are compared to the CPU run times.
