          Hello,<br>
          <br>
          Sorry for dummy question, but what are options for parallel
          ILU in petsc? Which packages are best for big sparse matrices
          (&gt;= 10^6)?<br>
          Where do I start from?<br>

        <div>I generally recommend against parallel ILU, but Hypre has
          it.</div>
