[petsc-users] Configure issues with scalapack

[Satish Balay]

I would:

- use 'top' to see where the hang is
- retry the build and see if the hang persists
- tweak compiler options [change from -O3 to -O2 or such, or use latest cmake] and see if that makes a difference.

Also note - the instructions for using Intel OneAPI MPI
