        Yes, it's a separate multithreading-based solver package. I noticed that PETSc support SuperLU (sequential package) and SuperLU_DIST through the option "--download-superlu" and "--download-superlu_dist", but SuperLU_MT doesn't seem to exist. I'm gonna try to add it according to Pierre's suggestions and push into PETSc. Thanks, Matthew.

                                Dear PETSc team,<br>
<br>
I want to call the multithreading sparse direct solver SuperLU_MT in PETSc, Could I download by "--download-superlu-mt"? Or what is a good way to support calling SuperLU_MT interface in PETSc? Thank you.

                                Is it a separate package, or only configure arguments to SuperLU?
