If you have multiple uses of MUMPs solvers you can call this between each use so that a different directory is used for different MUMPS usage.</span><div><font color="#666666"><span><br></span></font></div><div><font color="#666666"><span> Barry</span></font></div><div><font color="#666666"><span><br></span></font><div><font color="#666666"><span><br></span></font><div><br><blockquote type="cite"><div>On Feb 28, 2022, at 2:22 PM, Sam Guo <<a href="mailto:sam.guo@cd-adapco.com" target="_blank">sam.guo@cd-adapco.com</a>> wrote:</div><br><div><div dir="ltr">Dear PETSc dev team,<div> I would like to set MUMPS OOC_TMPDIR programmatically on fly (instead of statically using <a href="https://petsc.org/main/docs/manualpages/Sys/PetscOptionsString.html#PetscOptionsString" target="_blank">PetscOptionsString</a><span>(</span><font color="#666666">"-mat_mumps_ooc_tmpdir"</font><span>, </span><font color="#666666">"out of core directory"</font><span>, </span><font color="#666666">"None"</font><span>, mumps->id.ooc_tmpdir, mumps->id.ooc_tmpdir, </span><font color="#4169E1">sizeof</font><span>(mumps->id.ooc_tmpdir), NULL);).
