<p>Dear All,</p>
<p>I had a question. For petsc configured with 128bit float, Is it
possible to use 64bit direct solver as mixed precision
preconditioner <span><span class="qkunPe">for krylov</span>
subspace iterative method?</span></p>
<p><span> If so , such as MUMPS or Pardiso can be used as efficient
parallel LU </span><span>preconditioner I think. <br>
</span></p>
<p><span>Regards<br>
</span></p>
