Monitoring Media Performance Metrics in Real Time

Intel® GPA provides a new feature for performance analysis of GPU-accelerated media applications.

Start analyzing the performance of your media application from monitoring of real-time metrics:

1. Click the Intel® GPA Monitor icon in the taskbar notification area and select Media Performance….
2. In the Media Performance dialog box check three green bars displaying GPU utilization in real-time:
   • GPU General Usage – shows the percentage of time either the execution unit (EU) or multi-format codec (MFX) of GPU was active
   • GPU Execution Unit (EU) Engine Usage – shows the percentage of time the EU array was active; the table provides a breakdown of the EU utilization per media operation type (for example, video-processing , encode)
   • GPU Multi-Format Codec (MFX) Engine Usage – shows the percentage of time GPU MFX was active; the table provides a breakdown of the GPU MFX utilization per media operation type  (for example, decode)

     Here is the description of all media operation types that appear under EU and MFX real-time bars:
     

     Operation	Description
     DECODE	Video decode
     VPP	Video post- and pre- processing
     ENCODE	Video encode
     GHAL3D	Non-media (3D graphic)
     Unknown	Unknown operation
