Respected Professor, Yes, I remember this discussion regarding not using --download mpich tag while installing Petsc happening on github as well.
Yes, I think I should now do it. Although it still remains a mystery to me, how and why openmpi got installed and is now clashing with mpich. Anyways, for the time being, I have edited my PATH, and using Petsc mpich as default. I must reinstall Petsc and deal.ii again. Is there a need to reinstall P4est as well ? Thanks a lot Prof. Bangerth and Timo for your help and suggestions.
