Developers who deploy applications across CPUs to GPUs are often challenged to find the best methods for analyzing and optimizing offload performance.

In Part 2 of this webinar series, technical consulting engineer Kevin O’Leary focuses on tuning software for optimal performance once hardware is available. He uses Intel® VTune™ Profiler, a performance analyzer that takes the guesswork out of cross-architecture improvements. (Part 1 of this series focuses on designing software for efficient offload even before hardware is available.)

Using a sample application written in Data Parallel C++ (DPC++), Kevin demonstrates how Intel VTune Profiler can:

  • Profile DPC++, OpenMP* offload, and code running on host and GPU processors
  • Collect the right data and turn it into rich, interpretable analysis
  • Identify the hot spots in your compute kernels, including which are key areas for optimization
  • Show how the GPU resources are being used and locate hardware bottlenecks
