@funsim requested support for spmv i.e. multiplication of Mat and a Dat, which is straightforward to implement for the PETSc based backends, but less so for the (current) CUDA and OpenCL backends. However with the plan of also moving CUDA and OpenCL to PETSc in the long term it may not be worth implementing support for this operation on device for now. Thoughts?

We can do this on opencl right now, no? Since we build petsc datastructures for the solve anyway. On cuda, cusp gives us an spmv operation, so that might be straightforward, given we already build that datastructure for the solve.

I'm going to close this, because it hasn't come up as an issue.
