#include "petscvec.h" PetscErrorCode VecScatterRemap(VecScatter scat,PetscInt *rto,PetscInt *rfrom)Collective on VecScatter Many br
scat | - vector scatter context Many br | |
from | - remapping for "from" indices (may be NULL) Many br | |
to | - remapping for "to" indices (may be NULL) Many br |
Many br
Notes: In the parallel case the todata is actually the indices Many brfrom which the data is TAKEN! The from stuff is where the Many brdata is finally put. This is VERY VERY confusing! Many br
In the sequential case the todata is the indices where the Many brdata is put and the fromdata is where it is taken from. Many brThis is backwards from the paralllel case! CRY! CRY! CRY! Many br
