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_DECIDE
to have calculated ifN
is given)N - global vector length (or
PETSC_DECIDE
to have calculated ifn
is 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.
