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#
v - the vector
a - the HIP device pointer. This pointer is invalid after
VecHIPRestoreArrayRead()
returns.
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.
