DMGlobalToLocalBegin#

Begins updating local vectors from global vector

Synopsis#

#include "petscdm.h"          
#include "petscdmlabel.h"     
#include "petscds.h"     
PetscErrorCode DMGlobalToLocalBegin(DM dm, Vec g, InsertMode mode, Vec l)

Neighbor-wise Collective

Input Parameters#

Notes#

The operation is completed with DMGlobalToLocalEnd()

One can perform local computations between the DMGlobalToLocalBegin() and DMGlobalToLocalEnd() to overlap communication and computation

DMGlobalToLocal() is a short form of DMGlobalToLocalBegin() and DMGlobalToLocalEnd()

DMGlobalToLocalHookAdd() may be used to provide additional operations that are performed during the update process.
