This is my Contribution to Challenge:
https://github.com/yago5656/moonwalker
All the logic lies on clock.cu
expected result (testing with #20)
As you see this is a dirty script to understand and use CUDA to search the solution, you can start using this as your starting point to build more complex CUDA solvers !
actually this script is slow ! I need some help from community to speed up and fix some probable wrong points
PS: Don't use it on Visual Studio, it will not work ! this mod is for linux only (CUDA 12.2)
just change clock.cu as you want and:
and then
to run
let's get ahead, cheers

As you see this is a dirty script to understand and use CUDA to search the solution, you can start using this as your starting point to build more complex CUDA solvers !
actually this script is slow ! I need some help from community to speed up and fix some probable wrong points
PS: Don't use it on Visual Studio, it will not work ! this mod is for linux only (CUDA 12.2)
just change clock.cu as you want and:
Code:
make
and then
Code:
./clock
to run
let's get ahead, cheers
