My first parallel programming project with CUDA - N-body Simulation

[fair horizon]

This is a project I worked on to practice parallel programming with CUDA. It is on N-body simulation and utilizes the Barnes-Hut algorithm to simulate the stars and planets under the influence of gravitational forces. I've implemented spiral galaxy and galaxies collision. The visualizations are not the prettiest, but you can find them through the README's of the repo.

Feel free to share any other interesting parallel programming project ideas that I can work on next!

that's cool as fuck

can you post a video of the 2 galaxies but they start with some offset velocity so they go into more of a spiralling collision

I want to check it out, but cmake keeps saying no

[fair horizon]

You don't have to build it. You can watch it through the youtube links I just included above.

Oh

But I really want to run it on my pc

Just from the first 5 seconds, I agree with arson

[fair horizon]

You can run it on your pc if you got cuda compatible gpu or you can just run it on google colab

[remote hearth]

Yea, that's the thing

[fair horizon]

I just included the links for both videos. Is galaxy collision something you mean?

[sage acorn]

yea

Cmake is a mess, I think I'll try building it again tomorrow
