Add tuning script to reduce the load time of models

[ufechner7]

When using MTK we cache the simplified model in a serialized problem file. The load time of the problem can be reduced a lot (lets say from 20s to 5s) when this process is pre-compiled.

Idea: Create a script "tune" that does the following:

• create the required prob_xxx.bin file(s)
• trigger the package pre-compilation
• load the package and quit

Usage:

tune quasi-static=2,3,6 dynamic=2,3

--> create prob files for 2, 3 and 6 tether segments using the quasi-static model and prob files for 2 and three tether segments using the dynamic tether model and pre-compile the package such that all five problems can be loaded fast

Good idea. We should serialize the settings hash as well, to make sure that the serialized problems have the correct settings. And we should add the option to create quasi-static, dynamic or both.

I don't think we should serialize the settings.yaml file. The parameters in there should just be parameters of the serialized problem that can still be changed after loading the problem.

[1-Bart-1]

I agree that we should parameterize as much as possible. But not everything can be parameterized. The number of segments has to be fixed, the setting fixed_indes should be the same, and the PointMassSystem has to be the same. In general only scalar values can change, while segments/tethers etc. should stay the same.

Can this be closed?

[ufechner7]

No. Did you implement it? It would still be useful.

[1-Bart-1]

I did not. I don't know how to trigger the pre-compilation.

[ufechner7]

To trigger the pre-compilation is easy:

rm -rf ~/.julia/compiled/v1.11/KiteModels

OK, you need to know the Julia version before you can do this.
