MatSeqAIJRestoreKokkosView

Returns a Kokkos View obtained with MatSeqAIJGetKokkosView().

Synopsis

PetscErrorCode MatSeqAIJRestoreKokkosView(Mat, Kokkos::View<const PetscScalar *> *)

Not Collective, No Fortran Support

Input Parameters

• A - the matrix in type of MATSEQAIJKOKKOS

• kv - the Kokkos View previously obtained with MatSeqAIJGetKokkosView()

Notes

If the matrix is not of type MATSEQAIJKOKKOS, an error will be raised.

When the matching MatSeqAIJGetKokkosView() returned a non-const View, the device side of the matrix is marked modified so subsequent PETSc operations see the new values. The const overload is a no-op.
