[petsc-dev] VecScatterInitializeForGPU

[Dominic Meiser]

Hi,

I'm trying to understand VecScatterInitializeForGPU in 
src/vec/vec/utils/veccusp/vscatcusp.c. I don't understand why this 
function can get away with casting the fromdata and todata in the inctx 
to VecScatter_MPI_General. Don't we need to inspect the VecScatterType 
fields of the todata and fromdata?

Cheers,
Dominic
