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.

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?
