VecCreateMPIHIP#
Creates a standard, parallel, array-style vector for HIP devices.
Synopsis#
#include <petscvec.h>
PetscErrorCode VecCreateMPIHIP(MPI_Comm comm, PetscInt n, PetscInt N, Vec *v)
Collective, Possibly Synchronous
Input Parameters#
comm - the MPI communicator to use
n - local vector length (or
PETSC_DECIDEto have calculated if N is given)N - global vector length (or
PETSC_DETERMINEto 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.
This function may initialize PetscDevice, which may incur a device synchronization.
