Hi,


I have an APU AMD A10 -7850K with the latest AMD APP SDK 2.9 as well as the latest Catalyst Drivers 14.4.

The OS is redhat 6.3


As a part of the installation for the SDK it set's up LD-LIBRARY_PATH to the path to it's own libOpenCL.so.

However when LD_LIBRARY_PATH is not set I see 3 devices (it falls back to use /usr/lib64/libOpenCL.so) :


AMD A10-7850K APU with Radeon(TM) R7 Graphics

Tahiti

Spectre


when LD_LIBRARY_PATH is set to the AMD SDK's libOpenCL.so, the Spectre is missing.

Does anyone know why this is? I am using clinfo to see the devices


P.S. I have set the DISPLAY=:0 and chmod'd 666 the 2 devieces /dev/ati/card[0-1]
