VecCUDARestoreArray#
Restore a CUDA device pointer previously acquired with VecCUDAGetArray().
Synopsis#
#include "petscvec.h"
PETSC_EXTERN PetscErrorCode VecCUDARestoreArray(Vec v, PetscScalar **a)
Not Collective; No Fortran Support
Input Parameters#
v - the vector
a - the CUDA device pointer. This pointer is invalid after
VecCUDARestoreArray()returns.
Note#
This marks the host data as out of date. Subsequent access to the
vector data on the host side with for instance VecGetArray() incurs a
data transfer.
