    AMD OpenCL runtime conflicts with Intel's

    timchist

      Hi all,

       

      I'm using an Intel i7 3770K CPU that has an integrated GPU with OpenCL capabilities (HD Graphics 4000). OpenCL support is built into the graphics driver from Intel. I also have a discrete GPU -- AMD HD 7970 supporting OpenCL, this support also implemented in a driver (this time AMD's).

       

      The problem is that after I install the AMD's driver Intel's GPU is no longer accessible via OpenCL. There are two OpenCL platforms present in the system, but the Intel's one only sees CPU (AMD's sees both CPU and GPU). Before the installation of the AMD driver Intel's platform sees two devices: the CPU and HD Graphics 4000.

       

      Is it a known issue?

       

      Regards,

      Tim
