I've added CMake files to the project, which should simplify building with different SDKs a lot. benchmark_ocl can now be built like follows (NOTE: load cmake module on HLRN; add OpenCL-specific CMake stuff as needed).

mkdir build
cd build

cmake -DCMAKE_BUILD_TYPE=Release -DDEVICE_TYPE=CL_DEVICE_TYPE_CPU -DNUM_ITERATIONS=5 -DNUM_WARMUP=1 -DINTEL_PREFETCH_LEVEL=0 -DVEC_LENGTH=4 -DVEC_LENGTH_AUTO=16 -DOCL_BUILD_OPTIONS=""  ..

make -j

This will create a build of benchmark_ocl and all dependencies inside the folder build. The variables from the old make_ocl.sh are just passed through via -D ... here, so in a cmake_ocl.sh script, the build function can be replaced by a cmake call like above.

The build dir should be called build.<archictecture>.<sdk_suffix>. The script could then take additional input via the environment or command line:

# example values
BUILD_DIR_SUFFIX= # e.g. intel_sdk_for_opencl_2017_7.0.0.2511_x64
CMAKE_OPTIONS="-DOpenCL_FOUND=True -DOpenCL_LIBRARY=${HOME}/Software/ocl_sdks/intel/intel_sdk_for_opencl_2017_7.0.0.2511_x64/opt/intel/opencl/exp-runtime-2.1/lib64/libintelocl_2_1.so"

Good luck. :-)

Could you please list the deviation (host and device results) of all the OpenCL kernels running on a CPU or a GPU ?

Thanks
