VecCreateMPICUDA
Creates a standard, parallel array-style vector for CUDA devices.
Synopsis
#include "petscvec.h"
PetscErrorCode VecCreateMPICUDA(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 if N is given)
- N - global vector length (or PETSC_DETERMINE to have calculated if n is given)
Output Parameter
. v - the vector
Notes
Use VecDuplicate() or VecDuplicateVecs() to form additional vectors of the
same type as an existing vector.
