VecCreateShared#
Creates a parallel vector that uses shared memory.
Synopsis#
#include "petscvec.h"
PetscErrorCode VecCreateShared(MPI_Comm comm, PetscInt n, PetscInt N, Vec *v)
Collective
Input Parameters#
comm - the MPI communicator to use
n - local vector length (or
PETSC_DECIDEto have calculated ifNis given)N - global vector length (or
PETSC_DECIDEto have calculated ifnis given)
Output Parameter#
vv - the vector
Notes#
Currently VecCreateShared() is available only on the SGI; otherwise,
this routine is the same as VecCreateMPI().
Use VecDuplicate() or VecDuplicateVecs() to form additional vectors of the
same type as an existing vector.
