DALocalToGlobal
Maps values from the local patch back to the global vector. The ghost points are discarded.
Synopsis
#include "petscda.h"
PetscErrorCode PETSCDM_DLLEXPORT DALocalToGlobal(DA da,Vec l,InsertMode mode,Vec g)
Not Collective
Input Parameters
Output Parameter
g -the global vector
Note
This routine discards the values in the ghost point locations. Use
DALocalToGlobalBegin()/DALocalToGlobalEnd() to add the values from the
ghost points.
The global and local vectors used here need not be the same as those
obtained from DACreateGlobalVector() and DACreateLocalVector(), BUT they
must have the same parallel data layout; they could, for example, be
obtained with VecDuplicate() from the DA originating vectors.
Keywords
distributed array, local-to-global
