And I quote:

You're still writing in C, just using D to make an (extern) function 
call.  So it's not exactly D on the GPU, so I don't think it counts - 
plus the build sequence to build the C part with GCC->NVCC pass-through 
(or the MSVC->NVCC pass-through) would be a absolute nightmare to work with.

I looked into OpenCL, which appears (at first glance) to be a funky way 
of stringing together assembler instructions using C function calls. 
I'm sure it's fast, but it's not the most friendly looking code to me 
(then again, I don't know ASM, so what do I know?)
