The Elixir way of doing it is System.schedulers/0 or System.schedulers_online/0, where the former is the total number of schedulers, and the latter is the total number of schedulers which are active (i.e., actually being used)

The :erlang module provides this information with a system_info call:

:erlang.system_info(:schedulers_online)

Erlang abstracts CPUs away as "schedulers", and this API allows you to query how many are available.
