Hey! I've been doing scientific computing in Python&co (numpy, torch etc.) for awhile now. Realizing that many things deep down remain some sort of Fortran, I'd like to learn more about this final layer. I see there are many standards etc., which makes one wonder, is there a go-to list of resources for newcomers targeting modern scientific Fortran? Thanks!
The canonical reference is "Modern Fortran Explained: Incorporating Fortran 2018" by Metcalf, Reid, and Cohen. It is accurate but terse. More pedagogical but deliberately less complete (focusing on modern Fortran) is "Modern Fortran: Building efficient parallel applications" by Curcic. Many tutorials are listed at the Fortran Wiki <a href="https://fortranwiki.org/fortran/show/Tutorials" rel="nofollow noreferrer">https://fortranwiki.org/fortran/show/Tutorials</a> . Fortran Discourse <a href="https://fortran-lang.discourse.group/" rel="nofollow noreferrer">https://fortran-lang.discourse.group/</a> is an active forum.
How much modern Fortran is out there and what are people doing with modern Fortran?<p>On the rare occasions I see jobs seeking people with Fortran knowledge it tends to be in scientific fields where they wants a scientist who can muck around with legacy code.
>>> is there a go-to list of resources for newcomers targeting modern scientific Fortran?<p>There needs to be! Silo'd in DoE labs, it's retiring with the greybeards ;)<p>Learning from NVidia (same with vulkan). Target: jetson real-time image analysis.<p>But it's so fast on device I would host production services in multi-gpu fortran without reservation (if i had wall street level math loads + gpu cluster):<p><a href="https://on-demand.gputechconf.com/gtc/2013/presentations/S3050-Intro-to-CUDA-Fortran.pdf" rel="nofollow noreferrer">https://on-demand.gputechconf.com/gtc/2013/presentations/S30...</a>
