<p class="MsoNormal">Hello PETSc developers,<u></u><u></u></p>
<p class="MsoNormal"><u></u> <u></u></p>
<p class="MsoNormal">I am having some issues with using MUMPS solver after the solution phase from PETSc. I am solving a matrix equation with about 2.17 million DOFs and for 1764 RHSs. MUMPS successfully solves the system for all RHS; however, after the solve
phase the distributed solution from MUMPS vector/matrix is scattered back to PETSc mpi vector (done within PETSc) and this is where I am getting the error.
<u></u><u></u></p>
<p class="MsoNormal"><u></u> <u></u></p>
<p class="MsoNormal">FYI, when I use 1323 RHSs, there is no issue. Moreover, I had to use v3.18.6 (or lower) because of some compiling issue with v3.19+ and SuperLU_DIST on our cluster with older intel mpi.
<u></u><u></u></p>
<p class="MsoNormal"><u></u> <u></u></p>
<p class="MsoNormal">Any help is greatly appreciated. Thanks.</p></div></div></div></blockquote><div><br></div><div>Have you configured with 64-bit indices?</div><div><br></div><div> Thanks,</div><div><br></div><div> Matt</div><div> </div><blockquote class="gmail_quote" style="margin:0px 0px 0px 0.8ex;border-left:1px solid rgb(204,204,204);padding-left:1ex"><div class="msg-8811726290652265571"><div lang="EN-US" style="overflow-wrap: break-word;"><div class="m_-4118899637568871307WordSection1"><p class="MsoNormal"></p>
