:orphan: # VecCreateMPIHIPWithArray Creates a parallel, array-style vector using HIP, where the user provides the device array space to store the vector values. ## Synopsis ``` #include PetscErrorCode VecCreateMPIHIPWithArray(MPI_Comm comm, PetscInt bs, PetscInt n, PetscInt N, const PetscScalar gpuarray[], Vec *v) ``` Collective ## 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) - ***gpuarray -*** the user provided GPU array to store the vector values ## Output Parameter - ***v -*** the vector ## Notes See `VecCreateSeqHIPWithArray()` for further discussion, this routine shares identical semantics. ## See Also `VecCreateMPIHIP()`, `VecCreateSeqHIPWithArray()`, `VecCreateMPIWithArray()`, `VecCreateSeqWithArray()`, `VecCreate()`, `VecDuplicate()`, `VecDuplicateVecs()`, `VecCreateGhost()`, `VecCreateMPI()`, `VecCreateGhostWithArray()`, `VecPlaceArray()` ## Level intermediate ## Location src/vec/vec/impls/mpi/cupm/hip/vecmpicupm.hip.cpp --- [Edit on GitLab](https://gitlab.com/petsc/petsc/-/edit/release/src/vec/vec/impls/mpi/cupm/hip/vecmpicupm.hip.cpp) [Index of all Vec routines](index.md) [Table of Contents for all manual pages](/manualpages/index.md) [Index of all manual pages](/manualpages/singleindex.md)
