VecCreateMPIPThread

Creates a parallel vector using posix threads.

#include "petscvec.h"  
PetscErrorCode VecCreateMPIPThread(MPI_Comm comm,PetscInt n,PetscInt N,PetscInt nthreads,PetscInt affinities[],Vec *v)

Collective on MPI_Comm

	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_DETERMINE to have calculated if n is given)
	nthreads	- Number of local threads (or PETSC_DECIDE to have nthreads calculated)
	affinities	- Local thread affinities (or PETSC_NULL for PETSc to set affinities)

vv -the vector

Use VecDuplicate() or VecDuplicateVecs() to form additional vectors of the same type as an existing vector.
