The Platform Analysis group introduces analysis types monitoring CPU, GPU and power usage for your application/system.

  • CPU/GPU Concurrency enables you to explore code execution on the various CPU and GPU cores on your platform, correlate CPU and GPU activity and identify whether your application is GPU or CPU bound.

  • GPU Compute/Media Hotspots is targeted for applications using a Graphics Processing Unit (GPU) for rendering, video processing, and computations. If you ran the CPU/GPU Concurrency analysis and identified that your application is GPU-bound, use the GPU Compute/Media Hotspots analysis to go deeper and identify the most time-consuming GPU computing tasks and analyze performance per GPU hardware metrics.

  • GPU In-Kernel Profiling is targeted for GPU-bound applications and helps analyze GPU kernel execution per code line and identify performance issues caused by memory latency or inefficient kernel algorithms. This analysis type incurs a higher performance overhead.

  • System Overview is a driverless event-based sampling analysis that monitors general behavior of your target Linux* or Android* system and correlates power and performance metrics with the interrupt request (IRQ) handling.

  • Input and Output analysis monitors utilization of the IO subsystems, CPU and processor buses.

  • CPU/FPGA Interaction (preview) analysis explores FPGA utilization for each FPGA accelerator and identifies the most time-consuming FPGA computing tasks.

  • GPU Rendering (preview) analysis is targeted to estimate the CPU/GPU utilization of your code running on the Xen virtualization platform.

  • Platform Profiler (preview) analysis collects data on a deployed system running a full load over an extended period of time with insights into overall system configuration, performance, and behavior. The collection is run on a command prompt outside of VTune Amplifier and results are viewed in a web browser.


A PREVIEW FEATURE may or may not appear in a future production release. It is available for your use in the hopes that you will provide feedback on its usefulness and help determine its future. Data collected with a preview feature is not guaranteed to be backward compatible with future releases. Please send your feedback to


  • It is recommended to install the sampling driver for hardware event-based sampling collection types. For Linux* and Android* targets, if the sampling driver is not installed, VTune Amplifier can work on Perf* (driverless collection).

  • To enable system-wide and uncore event collection, use root or sudo to set /proc/sys/kernel/perf_event_paranoid to 0.
