Change Proposal Name OpenCL
Summary
This change will bring basic OpenCL support to Fedora to support the development of OpenCL enabled software and the development of OpenCL implementations itself.. This will include enabling Mesa's OpenCL state-tracker (in 9.3), packaging pocl - an CPU only OpenCL implementation - and the introduction of several other OpenCL related packages.

- Review Request: opencl-filesystem - OpenCL filesystem layout - A package owning shared paths DONE
- Package related packages
- Review Request: gocl - GLib/GObject based library for OpenCL - glib based OpenCL library DONE
- Review Request: clinfo - Enumerate OpenCL platforms and devices - A tool to query informations about the available OpenCL platforms DONE
- Package ViennaCL - A math library whcih can utilize CPU (OpenMP) and GPU (OpenCL/CUDA) WIP
- Package pyopencl - A python library for accessing OpenCL BLOCKED BY rhbz #1002898
- Update existing packages if needed
- gegl (to be investigated)
- ocl-icd (done)
- Potential projects to be packaged:
- Package beignet
- Package khronos icd - probably not
- Package radeontop - To monitor a Radeon GPU (which supports OpenCL)
- Package piglit - This will be a testuite for the OpenCL implementations
- Other stuff:
- Add a new group to comps or a opencl-dev package?
- Add virtual provides to the opencl implementations - So a app requireing opencl just needs to require the virtual package (so any provider)
- Version opencl-headers
Benefit to Fedora
