The CUDA kernel execution syntax is really just syntactic sugar, and
not needed for CUDA programming. My example code using cudaConfigure,
cudaSetupArgument and cudaLaunch seems impractical at first, but with
a C++ wrapper it becomes very convenient to use:
cuda::function<void (int, int*)> f = &kernel_function;
With nvcc and C++98, I was using the following wrapper. It's not the
nicest code, but it will look better with C++11 and variadic templates
to implement cuda::function.
Anyway, the kernel launching is only a side issue ;-).
