As OpenCL 2.0 is likely to be slower than 1.2, we recommend that this is used only where needed. (This is because 2.0 uses more registers and has lots of int64 operations, and some of the 2.0 features (pipes and especially device queues) are implemented in software so do not provide any performance gain.) Beignet will continue to improve OpenCL 2.0 performance. +This requires LLVM/Clang 3.9 or later, libdrm 2.4.66 or later and x86_64 linux. +As required by the OpenCL specification, kernels are compiled as OpenCL C 1.2 by default; to use 2.0 they +must explicitly request it with the -cl-std=CL2.0 build option.
