    We might not need OpenCL 2 support if we can get some nice C++ to spirv frontends and backends.

      SPIR is built on OpenCL 2.x.

        What's the status of OpenCL 2.0 on Linux in general? Does any of the drivers really support it nicely? Or do they crash? AFAIK the scientific community still pretty much relies on CUDA. OpenCL 2.0 is mandatory for nested parallelism.

          As far as i know.. OpenCL 2.0 is only working on AMD Proprietary drivers on Linux at the moment. Intel is at OpenCL1.2 and AMD Radeon OSS drivers (r600g) have a gallium 3d opencl driver (pretty sure thats at version 1.1 or 1.2 as well). So pretty much stuck with AMD proprietary drivers if you want OpenCL 2.0 at the moment on Linux. Its a shame, because the CUDA monopoly is growing stronger every day and by the time Intel & AMD catch up, it may be too late.

            The OpenCL 2.0 branch has a different (maybe new) name, OCL20.
            The Git log shows 69 commits in the 2 months to the Beignet 1.1.1 release, and 99 after 2015-10-08:
            Code:
            git clone git://anongit.freedesktop.org/beignet -b OCL20
            cd beignet
            git log --pretty=format:'' --after='2015-08-07' --until='2015-10-08' | wc -l  # 69
            git log --pretty=format:'' --after='2015-10-08' | wc -l  # 99
            I'm wondering why the new GEGL-OpenCL effort doesn't include Intel in the to-do list...
