I'm trying to run a GPU hotspot analysis but I'm stuck with the error message "Cannot collect GPU hardware metrics. Make sure the Intel OpenCL SDK of Intel Media SK is installed".
However, both are installed (from Media Server Studio 2018 R1). I can run and compile OpenCL GPU applications and vainfo executes correctly.
I'm running a fresh and clean install of Ubuntu 16.04 with kernel 4.15. The version of vtune is 2018 update 3.
The script "ampl-self-checker.sh" runs successfully but the generated report shows:
As far as I understand, with kernel 4.15, my i915 driver should be up-to-date and should not require any patching. Is this correct ?
Any help will be greatly appreciated.
Thank you for the report! I suggest that Metric Discovery(MD) library that is installed on your system cannot work with the 4.15 kernel. I recommend following:
Please note that MD library should be dynamically linked with libstdc++ 3.4.20 (or lower) or MD library should be linked with static libstdc++. If MD library is dynamically linked with libstdc++ > 3.4.20 you can use following workaround:
# LD_PRELOAD=/usr/lib/x86_64-linux-gnu/libstdc++.so.6 /opt/intel/vtune_amplifier_2018/bin64/amplxe-gui
