VecCreateShared

Creates a parallel vector that uses shared memory.

Synopsis

#include "petscvec.h"   
PetscErrorCode  VecCreateShared(MPI_Comm comm,PetscInt n,PetscInt N,Vec *v)

Input Parameters

comm - the MPI communicator to use
n - local vector length (or PETSC_DECIDE to have calculated if N is given)
N - global vector length (or PETSC_DECIDE to have calculated if n is given)

Output Parameter

vv - the vector

Collective

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.
