"Another notable change is the re-emergence of Fortran in the index at 20th position, up from 34th spot a year ago. Fortran, which emerged from IBM in the 1950s, remains popular in scientific computing. Its highest ranking on Tiobe's index was 10th in 2002.

Fortran was the first commercial programming language ever, and is gaining popularity thanks to the massive need for (scientific) number crunching. Welcome back Fortran.

The top 20 programming languages this month were: C, Java, Python, C++, C#, Visual Basic, JavaScript, Assembly language, PHP, and SQL, Classic Visual Basic, Delphi/Object Pascal, Ruby, Go, Swift, R, Groovy, Perl, MATLAB, and Fortran."

Noticed Fortran almost beating MATLAB which is on 19th place ?

To surpass it we need
- perfect %pl (must be publishable quality by default)
- add surfaceplot
- add 3D plot (OpenGL)

I have surfaceplot and OpenGL implemented, they are not difficult to do

Also
- perfect run speed on Polyhedron tests
- add Wininet (sockets)
- add support of OpenMP and create examples
- add support of HDF5 + examples

Dan you intrigued me with "surface plot". Is this a routine that uses "Z" data in addition to an X and Y to interpolate thicknesses at various positions?

Yes. In simple form it is like here. Done with current %GR quarter century ago. Same can be done with %PL

in more complex like here. Bottom is 3D, top - surface plot. Essentially it is 2D plot in 3D. Both done in OpenGL. Difference in programming almost zero

I published sources demo many times here. With OpenGL the only what's left is to add numbering like in the 3D picture. I modified existing OpenGL example supplied with Silverfrost Examples without even learning OpenGL

Other examples. Surface plot at the bottom

Good to add a pie chart

You sent me these OpenGL examples to use for learning some of the ins/outs of OpenGL. Much appreciated.

I am not sure what to make of it when Assembler is in the top 20.

Assembler became popular lately because of extensive use of testing by everyone on the net. Beating competitors just by the factor of 1% immediately makes you the winner of universe and all others bite the dust.

Can the Polyhedron tests be disassembled to understand why gfortran and IVF sometimes beat by the factor of 2-5-10 and even 30?

Look at that. Fortran jumped on 12th place.
Because it is Simplest. Fastest. Best.
And on supercomputers C and Fortran are like a king and queen.
Only utter @#$% think Fortran is dead.

By switching from the code written in C to Fortran i got so large boost in performance that i used just the PC and did not use supercomputers for almost a year.

That was amazing year. With this and other tricks we got the code run speed up by 5 orders of magnitude. Imagine, the code which on supercomputer 1000-2000 cores ran for two weeks ending on PC in 20 minutes! When for first time i ran this code i though it quickly crashed. But then i saw full directory of data Rolling Eyes

All that got me to realize one pity thing. Unfortunately it is impossible to satisfy humans. I got one task which grabbed all that extra power and even 100x more so that I recently returned to supercomputers again Sad

Got one more order of magnitude compared to previous 16-core AMD 5950x...Look at this thread count. Interesting that i got 1.35 times boost in speed going from 6 memory channels to 12. So appears this indeed is important.

And i made it incredibly cheap for that kind of performances, guarantee you will not believe me...

TIOBE Index for August 2024 :
Fortran steadily going to the top.
From 20th to 10th place already.
And ahead of MATLAB

/** And if Silverfrost
- made its compiler for Linux
- with MPI and OpenMP parallelization,
- with standard Makefiles and preprocessing language similar to other Fortran compilers
- with SDBG64 debugger capable to debug MPI parallel files (unbelievable, but there are no friendly graphics debuggers among all Linux compilers, they debug like Neanderthals planting PRINT into the code )
- added Clearwin for Linux and made more flashy scientific graphics examples including OpenGL
- made more freindly Plato for Linux
- optimized run speed beating at least Gfortran
- and advertised it at least ones in last 25 years

***it would be in the first 5***

Run on GPU.
Colleague rewrote the program to run on NVIDIA GPUs instead of regular CPU and reported that he got the speedup 173x from just single GPU !!! When Silverfrost adopts NVIDIA CUDA?

John, I do not know what is dan-talk - ?

I am waiting for confirmations from other people but the more i know about GPU the more i feel that such speedups are typical without any special trickery. But again, we always need double check
