Hello all!

I'm a Qemu user for a long time and I'm very satisfied by its features of flexibility, power and portability - really a good project!

Recently, reading some technical articles over internet, I have discoverd the big potentialities of the CUDA framework in relation to the scientific and graphic computing that takes strong advantage from the most recent GPUs. Someone has used it for password recovery, realtime rendering, etc, with great results.

It would be possible to use this technology in the Qemu project to achieve better performance? It could be a significative step for the develop in virtualization technology?

Someone, for example, in experimental way, has (re)wrote the md-raid kernel modules using the CUDA framework to accelerate the reed-solomon features... and it seems that works fine.
Why not for Qemu or related components?

The main question is about the dynamic transaltion engine: can it be modified for this framework? Someone says that Qemu is NOT parallelizable... but it seems strange because by definition is "Fast and Portable".
Not portable on this framework?
Pay attention, the computing on GPU is driven through a kernel module, not directly.

What do you think about this draft idea? It's just a proof-of-concept, but I hope to be useful.

Any feedback is welcome...
