【The use of HypreParVector】

[cglwdm]

I have a code as below to glue the local Vector FF to the HypreParVector X00, the FF will access the not-self part of X00 on every process: so the code is all right when mpirun -np 1, but get corrupted size vs. prev_size if I run it more than one processes.
So how to fix it? Or how to prevent FF from accessing the not-self part of X00 on a given process?
`
Array dofs;

HypreParVector X00 = X0;

for (int id = 0; id < pmesh->GetNE(); id++) {

            Q_space->GetElementDofs(id, dofs);

            for (int edge = 0; edge < 3; edge++) {

                if (dofs[edge] >= 0) {

                    index = dofs[edge];

                } else {

                    index = -dofs[edge] - 1;

                }

                X00(index) = FF(edge);

}
}

I have work out the problem, just use ParGridFunction as:
ParGridFunction pi_p(Q_space); for (int id = 0; id < Q_space->GetNE(); id++) { Array<int> dofs; Q_space->GetElementVDofs(id, dofs); pi_p.SetSubVector(dofs, FF); }
Everything is OK now!
