Sets an estimate of the number and type of upcoming mkl_sparse_?_sorv operations.
stat = sparse_status_t mkl_sparse_set_sorv_hint(type, A, descr, expected_calls)
Use the mkl_sparse_set_sorv_hint routine to provide the Inspector-Executor Sparse BLAS API an estimate of the number of upcoming forward/backward sweeps or symmetric SOR preconditioner operations for performance optimization.
