Add Runge-Kutta benchmarks about benchmarks

[awvwgk]

While I'm happy to see fpm used outside the Fortran community, it also shows some risks when not used properly.
In this case, it looks like they used Haskell fpm's flag feature to link against pthread:

fpm build --flag -ldl --flag -lpthread

Luckily for them, this also disables the debugging flags and runtime checks from the debug profile.
Still, the Fortran timings could improve by actually enabling optimizations for the benchmark run.

I found a few more ODE integration benchmarks of Fortran vs Julia: https://github.com/PIK-ICoN/NetworkDynamicsBenchmarks

Good catch! I didn't even pay attention to the fact they are using fpm.

Shows that we need to improve fpm to be usable easily by the outside community.

Hi all! I put that Fortran benchmark together. It was my first foray into FPM. I had expected it to go more smoothly.

I couldn't determine how to choose flags using the Fortran FPM, thus I used the Haskell version. Optimizations flags were also added using the --flags feature (I explicitly indicated all my desired flags).

Can you clarify: Does using a '--flag' disable all existing flags in the --debug profile? Is this documented somewhere?

Thanks for any input or improvements regarding use of the fpm tool. I'm pleased to see effort into a unified Fortran package manager and had hopes it would go a bit more smoothly than it did. It seems to me most features are undocumented. You'll see I also hacked the Flibs sqlite wrapper to use FPM for this little project, but it isn't using the fpm build system in a good way: https://github.com/Lima-Lima/fsqlite

Hi Lucas, as the author of fsqlite (and Flibs) I am interested in the issues you found. I have not tried it myself yet, but it should be a nice exercise - for both fsqlite and fpm :). Op di 30 mrt. 2021 om 08:41 schreef Lucas ***@***.***>:
