want a replacement of cuda driver api

[GoogleCodeExporter]

Hi, I'm developer of Alea.cuBase (http://www.quantalea.net), which is new CUDA 
tool in Microsoft new F# language. We developed a kernel DSL using F#, and 
generate LLVM and finally compiled into PTX by nvidia backend.

So now I'm seeking a way to make it possible to run PTX on other platforms, 
such as AMD, Intel Phi, etc. OpenCL is one way, but it need lot of work. I 
wonder if gpuocelot would help. In the backend, we use NVIDIA Driver API call, 
using .NET P/Invoke to call the nvcuda.dll (installed by driver) directly, so 
we bypass any stuff related to C language, even we don't need nvcc toolkit.

But I saw gpuocelot uses CUDA Runtime API. So my question are:
1) is it possible to provide a dll that simply replace the nvcuda.dll but with 
the same CUDA Driver API interface?
2) Will it support Intel Phi?

Regards,
Xiang.
