Don't forget that this is OS RESEARCH! Architecture is the first step ("Embrace..."). Next up -> Gallium when it's ready, so it'll 'run' on non-nVidia hardware ("... extend..."). After that it's killing CUDA ("knife the baby") and "... Extinguish!".
This is the tried and proven Microsoft way to operating system succes. Who's gonna disprove me on that? ;D

Originally posted by Veerappan View PostI'm not a huge fan of CUDA, but if I remember correctly, the nvcc that Nvidia open-sourced a while back was LLVM-based. If that's the case, a CUDA state tracker that can output LLVM IR might be feasible without too much effort. And once we've got LLVM IR, we might also be able to run CUDA programs on CPU/R600/Nouveau/other (assuming the user is willing to recompile their programs targetting that architecture). OpenCL is still better for us in the long run, but it would be useful to be able to execute CUDA code via the OSS drivers, even if just to ease porting to OSS CL implementations.

Kidding. I don't think going with vendor dependent things in the situation CUDA is in, is a very good idea.
(And in this case, I have some technical grounded reservations.)

Sounds awesome, but I'm sure Linus will get a few laughs from the proposal to run CUDA kernels... in the Linux kernel. It'll go something like "hahahahahahahahahahahaha NO". If we can't even do floating point or C++, how can we do something this "heavy" in the kernel?
Also: don't confuse this project with "gudev" -- I almost did at first

Gdev: A Competitive Open-Source CUDA Implementation
Phoronix: Gdev: A Competitive Open-Source CUDA Implementation
Shinpei Kato, the developer that last year at XDC2011 Chicago presented TimeGraph as an open-source GPU Linux command scheduler and PathScale's GPGPU run-time, has something new to share. Shinpei's latest project is Gdev, which comes down to being an open-source CUDA implementation that's competitive to NVIDIA's proprietary stack...
