Get Started with Intel® GPA

 
Use the Get Started document to run basic system and frame analysis using your own application:
Notes
  • GPU metrics collection limitations:
    • If more than one application are launched from Graphics Monitor simultaneously, GPU metrics are collected only for the application on the foreground.
    • If the System Analyzer is attached to a running application or the System View, GPU metrics are collected for the application, to which the System Analyzer is attached.
    • If a frame is open in Graphics Frame Analyzer in parallel with an application launched from Graphics Monitor, GPU metrics are available only in Graphics Frame Analyzer.
    • For applications, which use Intel® Metrics Discovery API, Intel® GPA does not collect GPU metrics by default. To enable GPU metrics collection by Intel® GPA, disable the
      GPU Metrics Collection by Target Application
       toggle button in the Graphics Monitor.
  • To get GPU metrics for Vulkan-based applications in the Graphics Frame Analyzer on Ubuntu 16.04 or Ubuntu 18.04, enable the Vulkan VK_INTEL_performance_query extension. For detailed instructions, please see Known Issues and Limitations .
  • T
     o get GPU metrics in the Graphics Frame Analyzer on Ubuntu 16.04 or Ubuntu 18.04, set /proc/sys/dev/i915/perf_stream_paranoid to 0 upon every reboot of your system with:
echo 0 > /proc/sys/dev/i915/perf_stream_paranoid
 

Product and Performance Information

Intel's compilers may or may not optimize to the same degree for non-Intel microprocessors for optimizations that are not unique to Intel microprocessors. These optimizations include SSE2, SSE3, and SSSE3 instruction sets and other optimizations. Intel does not guarantee the availability, functionality, or effectiveness of any optimization on microprocessors not manufactured by Intel. Microprocessor-dependent optimizations in this product are intended for use with Intel microprocessors. Certain optimizations not specific to Intel microarchitecture are reserved for Intel microprocessors. Please refer to the applicable product User and Reference Guides for more information regarding the specific instruction sets covered by this notice.
