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).<br>

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

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.<br>

Any contributions are welcome :-)<br>

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

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.<br>

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

What are your time constraints?<br>
