p4est also uses MPI so yes.
By the way: after you install deal.II, you should run "make test" in

Respected Professor,
Yes, I remember this discussion regarding not using --download mpich tag
while installing Petsc happening on github as well.

I think, if I can disable openmpi somehow, I will be in good shape. This

I am surprised why it is not working. I can't recall what has changed.
I don't remember installing any new libraries. It was working till Monday.
Also, I have installed petsc with --download mpich tag but donot have any

and more importantly, it was working until monday.

This can happen if you have conflicting mpi libraries installed (for

Yes, you are right :).
When running with 4 mpi processes, all threads print their rank as 0.
Why is it broken all of a sudden. What is this problem called ? How do I
correct it ?
I don't know. Are you calling MPI_Init, for example?

Hello all,
I am working on a 3D solid mechanics problem using deal.ii.
