Do we need with this suite a nvidia/ati driver that executes the CUDA/OpenCL/Stream code?

Perhaps the FreeBSD Foundation can open a new project for it. Today it can be seen like a "lost-time-addon" for FreeBSD, but not only Maths/Physics/Chemistry can use GPGPU, it can be used by databases, compilers, servers, and more in a nearer future. For example, all algorithms to filter image and video (Scanner, PET, Astronomy, video de/compression, etc) are being ported to gpgpu and i can't use FreeBSD for this. > When we started working on the driver months ago one of the main > goals was to allow greater portability.

FreeBSD has better OpenMP capabilities by its network connections, i'll like to use it in the next HPC era. > For those curious why NVIDIA doesn't port CUDA to FBSD...
