Thanks a lot for your bounty contribution!

There is a small addition we would want to make in the tutorial.

For the code there may be a way to showcase one of TFHE-rs tree-like reduction (though you used the one from rayon) and there may be a trick to speed up the fill order routine by potentially doing more work but exploiting more threads on an m6i.metal AWS instance, the machine has 64 CPUS and 128 threads and 500 Gigs of ram

My suggestion would be to explore the proposed alternative approach (creating a dedicated function in your code) on a small use case for your dev machine (which has a lower amount of thread to see if the implementation works ok) and then we can bench that on the m6i.metal to see if we are gaining for the overall computation time.

Cheers

ok, we should have the updated infos for the cla bot soon, thanks

[IceTDrinker]

Thanks a few more detailed comments otherwise this looks very good.

We'll probably manage the location in our docs ourselves to make it easier and avoid additional back and forth on this PR.

Cheers!
