It's time for me to focus a lot of my energy to learning FORTRAN for high performance coding. My strongest language is by far C#, so this should be a very interesting experience to say the least. I will try and document the transition from such a modern language to FORTRAN in case someone else finds themselves going through a similar language transition.
Simply getting started is quite an awakening; it's obvious from a few google searches that the community base is much smaller and information harder to come by. Just finding a compiler is not so trivial. The most promising and expensive looks to be Intel's, but it looks like gfortran is the way to go...
Downloading and installing gfortran was very straightforward. Now for the long line of tutorials

UPDATE:
Am also going to checkout Photran
