Sounds like a nice Google SoC project or > even something funded. This project is by far too much for a gsoc student not to mention who would mentor it... People throw around the term "GPGPU/CUDA" too much and don't realize that it breaks down into... 1) Kernel drivers (not ported to FreeBSD - see PSCNV.. There has other related things like drm, firmware. etc) 2) Runtime (do you need CUDA API, OpenCL.. etc) 3) Assembler 4) Code generation (ptx, direct isa.. which can be nv50, nvc0. etc) 5) Programming model (front-end which is typically CUDA/OpenCL or lesser known HMPP)
