Hi,

I like the idea of having separate VECCUDA and VECVIENNACL, because it is possible to implement VECCUDA without dependence on a C++ compiler (only the CUDA compiler).

I don't understand this part. NVCC also requires a C++ host compiler and is fairly picky about the supported compilers.

If you want, we can prepare a rough initial implementation of VECCUDA in the next days, and we can later discuss what to keep/discard.

Any contributions are welcome :-)

Karl: regarding the time constraints, our idea is to present something at a conference this summer, and deadlines are approaching.

Ok, this is on fairly short notice considering the changes required. I recommend to start with copying the CUSP sources and migrate it over to VECCUDA by replacing any use of cusp::array1d to a raw CUDA handle. Operations from CUSP should be replaced by CUBLAS calls.

Best regards,
Karli

If there is interest we can help in adding this stuff.

What are your time constraints?

Best regards,
Karli
