![]() ![]() = GPU device ID 2 : Intel(R) HD Graphics = = CPU device ID 1 : Intel(R) Core(TM) i7-5600U CPU 2.60GHz = When I list all available devices (mcxcl -L), I get the following output, there are 3, and 2 devices referred to the same CPU (i7-5600U): Platform Name Intel(R) OpenCL ![]() However, after both drivers are installed, I no longer be able to run my code on the GPU. Once the GPU driver is installed, my OpenCL code () can list and run my simulation on the HD 5500 GPU (speed =1200 photon/ms).Īfter I succeeded this step, I installed the Intel OpenCL CPU driver (opencl-1.2-sdk-5.0.0.43), with a hope that I can run my code on either device by a switch, or both simultaneously (I use "-G" and a 0-1 mask to select active devices). I first installed the OpenCL 1.2 Driver (86_64 ) for Intel HD graphics on my Ubuntu box (involving patching and installing Linux kernel 4.1), downloaded from the following link
