Colaborate With ft_utils

[SonicField]

The work here looks great. I see a lot of similarity between the atomics and those in ft_utils. Also, I'd love to learn more about the performance characteristics of the atomicdict.

Would you like to colaborate? How can we work best together? Seems at least we should make the atomic header stuff as common as possible.

All the best - Alex

Hi Alex 👋

Thank you for reaching out!
I would very much like to collaborate!

As for the performance of AtomicDict, some workloads are quite good now, while others definitely need improving.
In particular, the reduce method can perform very well.
There's the benchmark repo which hosts some performance comparisons.
In general you'll find that some workloads are already better than dict, and that it's still nowhere near the performance of a state of the art C++ hash table (unsurprisingly).
I've written something in my thesis, which is more human readable than plots and numbers, and goes more in depth if you're curious.

The ft_compat.h header that you have looks really neat with those macros, but I'm a bit confused. Don't you use stdatomic or something like that?
For cereggii's atomics I've opened #32 (which has a very thorough description, I know). I'd like to make it header-only and find out if there's a way for cereggii to be distributed so that it's easy for the header to be included by another package. I have absolutely no idea how to do this, but I think if we can work it out together, we can definitely save some time for both of us!
