But you won’t want to have to create the CUSP or ViennaCL objects on the fly each time from the CUDA/OpenCL “raw pointers”?

why not? I can just 'wrap' an existing memory buffer for use with the respective operations provided with the respective library.

So you mean like VecPlaceArray()? Ok.

Yes.

This is a big refactorization, probably more than what Lisandro is looking for in the short run.

Definitely.

So what do we do in the short run, provide VecCUSPGetCUDAArray() and VecViennaCLGetOpenCLArray()? I’m ok with that.

Agree'd. These are just simple wrappers on top of VecCUSPGetArrayRead()/VecCUSPGetArrayReadWrite() and VecViennaCLGetArrayRead()/VecViennaCLGetArrayReadWrite() I can add these over the weekend. Best regards, Karli
