Dear PETSc team,

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,

Yes, one would need to add it: https://github.com/xiaoyeli/superlu_mt

Gang, it would be a good exercise to make your first contribution to PETSc if you feel like it.

You should be able to copy/paste most of what is in config/BuildSystem/config/packages/SuperLU.py into a new file config/BuildSystem/config/packages/SuperLU_MT.py

Thanks,

Pierre

or only configure arguments to SuperLU?

Thanks,

Matt

Best Regards,
Gang
