Hi,

I haven't run benchmarks much since there's still functionality
missing.
You can try 'clpeak' to get rough fp32/fp64 throughput numbers.
luxmark-3.1 should also work out of the box, but the 'spehere' scene
gives ~30% incorrect pixels on the HW that I have.
luxmark-4.x needs ocl-1.2, but works if the version is overridden using CLOVER_PLATFORM_VERSION_OVERRIDE, CLOVER_DEVICE_VERSION_OVERRIDE, CLOVER_DEVICE_CLC_VERSION_OVERRIDE.
All three env vars take string, so you need to set it to "1.2".

there are other benchmarks that you can try, like JohnTheRipper or Rodinia. Note that anything that needs image support won't work.


regards,Jan
