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() or ISLocalToGlobalMappingCreateIS()

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
