I have been programming in fortran for about a year and a half since I
wrote my "Hello World" program. Since then my projects get bigger and
bigger and although I own two fortran manuals... Metcalfe, Reid and
Cohen, and Ellis, Phillips  and Lahey, I still do not know very well
how to set options on my compiler to make programs run fast or how to
do profiling of the programs... or something even more basic, how to
tell when your coding style are making things running slower than they
should. Soooo my question is if anybody knows about any good source to
self train your self
