[petsc-dev] Force synchronization of CUSP vector

[Jose E. Roman]

I would like to force the copy of a VECCUSP from/to the GPU. I need this in user code, in particular from within a shell matrix MatMult.

Both VecCUSPCopyToGPU() and VecCUSPCopyToGPU_Public() are declared PETSC_INTERN in a private header. The only public function is VecCUSPCopyToGPUSome_Public(). In the "From" variants, VecCUSPCopyFromGPU() is PETSC_EXTERN but declared in a private header.

Shouldn't these functions be public?
