Accelerators Analysis Group
- Use the GPU Offload analysis to profile applications that use a Graphics Processing Unit (GPU) for rendering, video processing, and computations. This analysis type helps you identify whether your application is CPU or GPU bound.
- For GPU-bound applications, use the GPU Compute/Media Hotspots (preview) analysis type to see the GPU kernel execution per code line. Identify performance issues caused by memory latency or inefficient kernel algorithms.
- To enable system-wide and uncore event collection, use root or sudo to set/proc/sys/kernel/perf_event_paranoidto0.$ echo 0>/proc/sys/kernel/perf_event_paranoid
