OpenCL-Layers

A collection of OpenCL layers.

Building

The layers in this repository can be built using CMake:

mkdir build
cd build
cmake -DCMAKE_BUILD_TYPE=Release ../
make

Using a layer

Layers are loaded and enabled by the OpenCL-ICD-Loader so applications have to use the ICD loader to be able to use layers.

On a Unix-like system, a typical usage looks like the following (taking the example of the object lifetime layer):

OPENCL_LAYERS=/path/to/OpenCL-Layers/build/object-lifetime/libCLObjectLifetimeLayer.so \
/path/to/application

This assumes that the the OpenCL-ICD-Loader is already installed on the system and configured to point to available ICDs (i.e. OpenCL implementation shared libraries).

If this is not the case, please refer to the full OpenCL-ICD-Loader documentation for how to install and configure the loader.

The following should however be useful in many scenarios:

LD_LIBRARY_PATH=/path/to/OpenCL-ICD-Loader/build \
OCL_ICD_FILENAMES=/path/to/vendor/libOpenCL.so \
OPENCL_LAYERS=/path/to/OpenCL-Layers/build/object-lifetime/libCLObjectLifetimeLayer.so \
/path/to/application
