1. Download the Intel Fortran compiler for your Mac, Linux or Windows
box. This will also give you a number of tuning tools. This compiler can
understand syntax back to FORTRAN-66 through Fortran2018 (and often
without any switches - it can usually figure it out and do the right thing).
2. Get a copy of

3. Go to the physics and chem depts a place start as Larry said
4. Or head to a supercomputer center in the US or EU

instead of increased. It has a lot to do with how floating
point works, it's not exact like integers are.
I was unaware that there's formal training to be had around this but
it's something I'd like to learn more about. Any recommendations on
materials? I don't mind diving into Fortran itself either.
