C++ AMP may be an open specification but it only targets DirectX. But
the ideas behind it are very sensible, use closures and internal
iteration with library support to drive the compiler to construct the
required kernels.

Today you have to download the kernel to the attached GPGPU over the
bus. In the near future the GPGPU will exist in a single memory address
space shared with all the CPUs. At this point separately downloadable
kernels become a thing of the past, it becomes a compiler/loader issue
to get things right.
