My impression was intel is mostly faster. However, does it apply to

I'll give it a go if it's so. However, I remember changing a no. of
options to build and in the end, it was slower. that's a few yrs ago though.
It varies, but usually not by a large factor and a broken compiler takes
infinitely long to produce correct answers. Report the bug to Intel,
use gfortran (latest version), and get on with your business. If/when
Intel fixes the bug, if you still have a license, try ifort again.
Actually in my original email, I mentioned that by using petsc.h instead
of petsc.h90, I was able to compile and build successfully. Running it
seems to be fine. I will try gfortran when I have the time and report my
results. Thanks!
