VecHIPRestoreArrayRead#

Restore a HIP device pointer previously acquired with VecHIPGetArrayRead().

Synopsis#

#include "petscvec.h"   
PETSC_EXTERN PetscErrorCode VecHIPRestoreArrayRead(Vec v, const PetscScalar **a)

Not Collective; No Fortran Support

Input Parameters#

Note#

If the data on the host side was previously up to date it will remain so, i.e. data on both the device and the host is up to date. Accessing data on the host side e.g. with VecGetArray() does not incur a device to host data transfer.
