Feature: Faster histogram construction when the number of bins exceeds 80#162
Merged
Conversation
This commit switches the `cloud-microphysics` `histogram_t` constructor to using a different algorithm when the number of bins reaches a threshold of 80, at which value the new algorithm outperforms the original algorithm. The original algorithm used `do concurrent`, but required accessing the entire data once per bin. The new algorithm is inherently serial, but only accesses the data set once, keeping a running tally of the bin count.
