I see the code in git hub https://github.com/AsteroidsAtHome/PeriodSearch last modificacion 3 years ago

in period searchmain
in the period_searh_optimization_cpu
input_period_search
period_searh_in_2263

only for visualize one of the task

...... a lot of numbres i think probably matrix and derivades calculations of Two methods are outlined for estimating the attitude and rotation of an object with a known shape and orbit using only light curve measurements :/ bayesian inference?, this methods, ...

i remember when use newthon rhapson and gauss seidel when system converge for caluclation of nodes electrical systems of power. ( in spanish) (calculaba los incrementos de los resultados de las matrices inversas, y si no convergía en el error hacia otra iteracion hasta que el sistema pasaba el error minimo fijado)

this is my work of system iterations (start page 64 of pdf) 4 nodes by hand, yes, BY HAND muahahaha one iteration of nwethon rhapson its toooo crazy

Its no have manual for understand how works the period search application,, but, i think, i can use deep seek R1 IA, (R1) for code , for understand.

i think this IA can write the code c... in python?

¿How works in the cpu this code? Can i see the code run with asembler or xdbg debugger , and see , the diagram fluxes?

I think what the IA can generate code for visulize the simulation (light curve) in boinc?, because only can see propierties of task

You can find the latest code in the "dev" branch.
period_search_optimization_simd (cpu)
period_search_opencl_amd (opencl)
period_search_cuda (cuda)

If you're trying to understand what the code does, it's easier to begin with the simpler version that doesn't include any SIMD or GPU optimizations.

There's no guide or comprehensive documentation, but you can find some resources about the math behind here

The app uses well-known algorithms like

https://en.wikipedia.org/wiki/Gaussian_elimination

> i think this IA can write the code c... in python?
AI can explain what each part does and write a similar code in Python for educational purposes, but you still need some math+dev background to understand it.

> Can i see the code run with asembler or xdbg debugger
Sure, if you can compile it... However, the assembly output won't provide much insight into what the code does.
