VecCUDARestoreArray#
Restore a CUDA device pointer previously acquired with VecCUDAGetArray().
Synopsis#
#include "petscvec.h"
PETSC_EXTERN PetscErrorCode VecCUDARestoreArray(Vec v, PetscScalar **a)
This marks the host data as out of date.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.
Input Parameters#
v - the vector
a - the CUDA device pointer. This pointer is invalid after VecCUDARestoreArray() returns.
Fortran note#
This function is not currently available from Fortran.
