This repo is a small Elixir performance arena for testing serial or parallel processing of big collections.
To test your algorithm:
- Open
lib/process_many.ex - Add your function. It must start with
process_and accept two parameters: (1) the collection and (2) a function that accepts one parameter and returns a new value. The name should ideally comprise of your GitHub username and a short description of the algorithm (e.g. mine isprocess_dimitarvp_parallel_chunk). - Run
