# VecCreateMPIHIPWithArrays
Creates a parallel, array-style vector using HIP, where the user provides the complete array space to store the vector values. 
## Synopsis
```
#include <petscvec.h> 
PetscErrorCode VecCreateMPIHIPWithArrays(MPI_Comm comm, PetscInt bs, PetscInt n, PetscInt N, const PetscScalar cpuarray[], const PetscScalar gpuarray[], Vec *v)
```
Collective, Possibly Synchronous


## Input Parameters

- ***comm     -*** the MPI communicator to use
- ***bs       -*** block size, same meaning as `VecSetBlockSize()`
- ***n        -*** local vector length, cannot be `PETSC_DECIDE`
- ***N        -*** global vector length (or `PETSC_DECIDE` to have calculated)
- ***cpuarray -*** CPU memory where the vector elements are to be stored (or `NULL`)
- ***gpuarray -*** GPU memory where the vector elements are to be stored (or `NULL`)



## Output Parameter

- ***v -*** the vector



## Notes
See `VecCreateSeqHIPWithArrays()` for further discussion, this routine shares identical
semantics.
