Nice, it says:

>We have adapted the superposition/convolution algorithm to the GPU using a combination of NVIDA's Compute Unified Device Architecture (CUDA) software development environment and the Digital Mars’ D programming language for our implementation.<

How have you used D with CUDA? I'd like to know a bit more technical details.
And do you know about BSGP (that I think is a step toward the future of such things)?
