Re: nVIDIA cuBLAS and GNU Octave

[Riccardo Corradini]

Daniel,
there is an open source implementation of the cuda driver api use the following libraries : drm and drm_nouveau.
On the upper level there is another open source library called gdev.
Please have look at the readme for nouveau driver
https://github.com/shinpei0208/gdev.
The missing part is the lack of a candidate for the substitution of nvcc with an opensource tool.
In theory llvm may work to generate the ptx.
there is also a compiler for ptx -> cubin for nvidia fermi architectures.
http://code.google.com/p/asfermi/
There is an initial hint on the path of llvm + dragonegg ...
See

Please fell free to contribute
Bests
Riccardo

I know Riccardo Corradini is working hard to get GPU computing into Octave without any non-free software tool,
I'm CC-ing him in case he has any comments.
