I recently installed the latest intel opencl sdk for Linux on two Ubuntu 14.04 boxes - one with nvidia graphics, one with AMD graphics, I found that neither clinfo nor my program can emulate the intel opencl platform. the only output is the nvidia opencl.
The intel ocl library was installed in the default path at
/opt/intel/intel-opencl-1.2-6.2.0.1760/opencl-1.2-sdk-6.2.0.1760/lib64/
however, under /etc/OpenCL/vendors/, there is only nvidia.icd. I checked my laptop where an old version of intel opencl sdk was installed, it has the intel64.icd file (with a single line: libintelocl.so). However, neither intel64.icd nor libintelocl.so could be found on the latest intel opencl sdk.
I also checked the release note about Linux installation, I could not find any discription on icd installation and LD_LIBRARY_PATH configurations

can anyone comment on how to make intel ocl work side by side with nvidia and amd opencl? thanks
if this is not possible with the latest sdk, where can I download the previous sdk packages?
