<A NAME="VecScatterFinalizeForGPU"><H1>VecScatterFinalizeForGPU</H1></A>
Finalizes a generalized scatter from one vector to another for GPU based computation. Effectively, this function resets the temporary buffer flags. Currently, this only used in the context of the parallel SpMV call in in MatMult_MPIAIJCUSP (in mpi/mpicusp/mpiaijcusp.cu) or MatMult_MPIAIJCUSPARSE (in mpi/mpicusparse/mpiaijcusparse.cu). Once the <A HREF="../Mat/MatMultAdd.html#MatMultAdd">MatMultAdd</A> is finished, the GPU temporary buffers used for messaging are no longer valid.
