The aim of this repo is to keep track of the optimization efforts in super_mass.
Short Bench time: [2.8952 ms 2.9133 ms 2.9316 ms]
change: [-3.7135% -2.9009% -2.0424%] (p = 0.00 < 0.05)

batch_size N/8 -> N/16 : increase batch count to get better load balancing. Short Bench time: [3.1212 ms 3.1328 ms 3.1444 ms]
use jemallocator as main memory allocator.

jobs count = 1 -> 8 : previously, the jobs parameter had no effect and always used all logical cores. There is no job parameter anymore by default and always uses all logical cores. Manually setting the thread count requires to disable the "auto" feature and calling init_pool
to init the global pool.

Parallelize the distance loop with a par_bridge from rayon_rs. Reduced batch size to N/8 for load balancing purposes.

JIT mean and standard deviation; complexity goes from O(nm) down to O(n) for m << n. Time complexity dominated by fft with O(nlogn).
