Solutions to Advent of Code puzzles using the Lamellar Runtime.

For most these problems, there appears to exist an efficient serial implementation, limiting the benefit of a parallel (and distributed) runtime. Still, this is an effort to explore Lamellar and provide some examples on how to use the runtime!

Generally, I will implement a serial solution as well as at least one Lamellar based solution.

I utilize the cargo-aoc crate as the execution harness.

install using cargo install cargo-aoc

run using cargo aoc optionally specifying a day with -d <day>

bench using cargo aoc bench optionally specifying a day with -d <day> and including the input parsing with -g

Run in WSL on an AMD 7950x
