So you seem to have completely ignored my statement about the issue of development vs running where I specifically pointed out that in an educational environment you compile many more times than you run.
in 1977 I had the task of taking students who had never seen a computer in real life, never logged into an account, never used a text editor of any type and try to teach them FORTRAN in a eight-week summer-school course of three hours of lecture each week.
I asked the administration of the school if anyone had ever taught this before in this time frame and was told "Oh yes".
In was a time-sharing system (RSTS/E on a PDP-11/70), so I had to teach them what "logging in" was, what a file was, what data was, what a text-editor did (and how to use the commands), what compiling did, what linking did, how to use an interactive debugger, then programming itself and the FORTRAN language itself.
None of the students had access to computers at home, and there were not many people who could help them at home. No online forums for help.
They struggled. I struggled. And after eight weeks they were barely getting started with very, very simple FORTRAN programs.
On the other hand I often taught a ten-week course in FORTRAN to students who already had BASIC as part of a entry-level course called "Introduction to Data Processing". The students of that course thrived due to a much greater familiarity to everything other than the edit/compile/link/run/debug process (and even editing and debugging were easier because the concept of that was already known).
BASIC allowed simple editing just by retyping the line number with the statement. It allowed interactive "debugging" by being able to print out the variables using the source code variable name, or setting the variable to a different value before telling the interpreter to "continue". in RSTS/E you were talking to the BASIC interpreter as soon as you logged in. The BASIC interpreter was much like the shell interpreter in UNIX/Linux today.
The student could type in:
Print 5*3
then hit return and the machine would print:
15
No editor, no compiler, no linker...
To be complete I know of no reason why FORTRAN could not be implemented in an interpreted fashion and after a program's source code is fully debugged sent through a "real" compiler to get a smaller, perhaps faster object. Once the program has been debugged you do not need the interactive debugger part of the program in memory.
And of course a more modern, fully functioning IDE could make the compile/link/execute/debug path significantly easier these days. And of course students today have used computers in so many ways through their phones, etc. that many of the concepts which I took up time in class the students already know.
Finally, I will say that when I finished the eight-week summer course in FORTRAN to what I felt were disastrous results I went back to the administration and questioned again if that course had ever been taught successfully before.
The answer was "no".....they had lied before.
/*But when the eventually approved and compiled code will be run every hour or so for the next 3-5 years, and that code requires MPI interconnection to 100-800 other nodes to run on every hour, devel/compile time starts looking to be less of a problem.
Pretty sure the heat generated to predict the weather has small but non-zero impact on the weather :-)*/
Quite frankly for this type of problem I might look at GPU or FPGA accelerators just like years ago we invented floating point accelerators instead of doing floating point using integer only CPUs.
Depending on the type of problem, a language like Erlang or Haskell would probably help with such a distributed problem

An interpretive language is much "faster" (and less of a resource hog) than running an edit/compile/link/execute cycle.

The scripting languages are easier to learn and definitely have a place. And they are now the gateway to programming. They're not perfect and they slurp down hardware. I can't imagine python trying to run in the days of BASIC on an early pc jr. :-)

They realized that the freshmen of today often knew less about computers than the freshmen of 20 years ago...the ones who 20 years ago downloaded source code and (in some cases) even had to COMPILE it and LINK it in order to run it.

I forgot the name of the magazine, but I would buy it every month and sit at my VIC 20, trying the code in, playing such games and Oil, where you drill to get oil hoping to hit a pocket with a devil in it. Or trying to understand what the data fields were doing.
