Explore advanced OpenACC profiling techniques in this first lecture of the Advanced OpenACC Course from May 2016. Dive into three ways to accelerate applications, learn about OpenACC profiling tools, and discover PGPROF, the OpenACC CPU and GPU profiler. Examine the exploration and production workflow in seismic data processing, including data acquisition, imaging techniques, and model verification. Analyze the pseudo-code for Kirchhoff migration, assess baseline CPU profiles, and learn parallelization strategies. Understand how Unified Memory improves productivity and its integration with OpenACC. Explore optimization techniques, including multi-core, OMP, and pthread implementations, and compare deployment results. Gain access to homework assignments and learn how to set up Seismic Unix for practical application.
