Error Message: Cannot Collect GPU Hardware Metrics for the Selected GPU Adapter

Possible error messages:
  • Cannot collect GPU hardware metrics for the selected GPU Adapter.

Cause

To collect GPU hardware metrics and GPU utilization data on Linux systems (or Windows systems with driver versions older than 27.20.100.8280 ),
VTune
Profiler
uses the Intel® Metric Discovery API library that is distributed with the product. This error message displays if
VTune
Profiler
cannot access the selected GPU adapter.

Solution

Make sure that you have set the
AMPLXE_TARGET_GPU
environment variable correctly. See a description of this issue in the
VTune
Profiler
release notes
to set the variable.
For Windows systems, update the driver for the selected GPU adapters.
For Linux systems, install a version of the Intel Metric Discovery API library that is newer than 1.6.0 to support the selection of video adapters. To collect metrics from the video card of your choice, disable other adapters in the BIOS first.
