VecSetLocalToGlobalMapping#
Sets a local numbering to global numbering used by the routine VecSetValuesLocal() to allow users to insert vector entries using a local (per-processor) numbering.
Synopsis#
#include "petscvec.h"
PetscErrorCode VecSetLocalToGlobalMapping(Vec x, ISLocalToGlobalMapping mapping)
Logically Collective
Input Parameters#
x - vector
mapping - mapping created with
ISLocalToGlobalMappingCreate()orISLocalToGlobalMappingCreateIS()
Notes#
All vectors obtained with VecDuplicate() from this vector inherit the same mapping.
Vectors obtained with DMCreateGlobaVector() will often have this attribute attached to the vector so this call is not needed
