<p>Dear PETSc Users,</p>
<p><br>
</p>
<p>I use the MUMPS wrapper in PETSc (loaded from dealii). I know that MUMPS computes a factorization based on the mulrifrontal method and since I have a very memory-strapped problem, I would like to run some test on the memory requirements for the factorizations
across some sets of parameters in my underlying FEM-problem.</p>
<p>My question is if there is a native way to check memory (as a measure of fill-in) for the MUMPS factorization in PETSc. I would prefer not to go through the operating system since that feels somewhat inconclusive to me. Does PETSc provide such functionality
in any way?</p>
<p>I would prefer to know the memory consumption for storing the factorization if that is possible, I would also take the total memory consumption of the direct solver if there is no other way, and, if nothing else is possible, I guess I would have to go with
the memory requirement of the whole application if all else fails.</p>
<p>Is anyone aware of something I can do?</p>
<p><br>
</p>
<p>Kind regards, </p>
<p>Pascal</p>
