What language will be most used to write new #HPC applications/code over the next few years?

#Fortran?

C/C++?

Julia?

Python?

Copilot / ChatGPT / other #AI prompt languages?

#CUDA?

I'm an HPC user of CPU Fortran compilers, and my primary/preferred compiler is__________"

Was für eine Freude. Mal wieder alten #fortran Code debuggen.

I would be a greybeard #UNIX guy if I could grow a non-scraggley beard, and it's unfair to the #DOGE teens to claim that the IRS and Social Security rely on ancient #COBOL code that only a few people alive actually understand. They also rely on ancient #FORTRAN code and even I never studied that at Computer Camp.

Pondering if I dare to put #Fortran into my CV.

I can do some Fortran, partly because it keeps coming up in all sorts of #retrocomputing contexts, but, even with Ratfor enhancements, I don't consider it a well-designed or pleasant language, and I'm not sure I can see myself working at a place that deals in new Fortran code now that nice, human-friendly languages such as NumPy and APL have been invented. Besides, 21st century Fortran is a really weird language that doesn't even know what it wants to be when it grows up.

The original #LISP had 7 primitives: \(\texttt{cons}\), \(\texttt{car,}\) \(\texttt{cdr}\), \(\texttt{atom}\), \(\texttt{quote}\), \(\texttt{eq}\), and \(\texttt{cond}\). And the original #Smalltalk syntax could fit on a 5×7 card. That meant a novice could learn the syntax in a matter of minutes, and direct all his efforts to learning how properly to wield the power of that Turing-complete language. This was why, in the 1970s and the 1980s, many college freshmen were taught FP in Scheme (a more modern LISP) and many middle school children were taught OO in Smalltalk. These were surely the best "first" #programming languages.

#FORTRAN and #BASIC were simple, too. FORTRAN, the first high-level language, has been in continuous use since the late 1950s by engineers, who are not keyboard warriors. BASIC was invented in the early 1960s for teaching programming to non-STEM students at Dartmouth. It sired a whole generation of self-taught children in the 1980s.

Compare those to C++, Erlang, Python, Haskell, Java, JavaScript, Scala, Rust, Kotlin, and pretty much every language in popular use today. Most consider Python and JavaScript to be the simplest of modern languages. Yet, they are massive, complex languages. No 10-year-old could teach himself those, nor should he.

The original versions of those classic languages cannot be used to solve modern problems. But they should still be taught to youngsters as their first language. Throwing in the kids' faces a modern enterprise language confuses them and discourages them. Consequently, many novices never attain that state of flow, when the joy of programming gushes forth.

#Simplicity is a virtue. Self-motivated learning is virtuous.

I don’t suppose there are Fortran bindings for Godot right?

I predicted¹ in 2014 that #julialang might replace #Fortran for #science and #engineering calculations. I think this process has begun and will continue.

In case you want to broaden your #programming skills. Fortran seems to be making a comeback (currently 11 in the Tiobe index: https://www.tiobe.com/tiobe-index/fortran/ ).

This is from 2017, written at the end of my Physics PostDoc where I used quite a bit of Fortran and learned to appreciate it much more than I expected.

Interested in #MPI and #OpenMP parallel programming to speed up your scientific applications written in #C, #Cpp, #Fortran or #Python (with #numpy)?

Attend our course in #Mainz at the Johannes Gutenberg University (#JGU) for a 4-day course from 1. April to 4. April 2025! We still have plenty of space available!

See our announcement page for further details and to register: https://indico.zdv.uni-mainz.de/event/34/

Note, it is an on-site course.

I don't remember much about #Markov Chains, #Random-Walk. Fokker-Planck. Jeez Louise. Scratched around trying to read and understand stuff. Fortunately at the time, my advisor cleared the decks, said don't bother, here is a 2-D #Gaussian dispersion model I wrote in BASIC. Re-write it in #FORTRAN and add two flavors: a #Lagrangian and a K-theory particle dispersion model, for a convective boundary layer. Use those formulations for a connective boundary layer you learned in Turbulence.

Waifuvault Unofficial #fortran SDK now supports albums.

Was a bit of a slog, even compared to the C SDK.

Still got docs to update, but thats for tomorrow me...

We wouldn't have this problem with DOGE's interns if they had to learn COBOL, FORTRAN, and PASCAL - like I had to.

BTW: My major programming language? Perl

Second only to Objective-C... NOT SWIFT. Obj-C!

Writing #python to parse SAS code to call #rust via FFI to generate #json to feed into a #javascript front end written in #typescript

Gotta get #fortran or #brainfuck in here just to round it off.
