"Pure parallelism" refers to the execution of pure Haskell functions on multiple
CPU cores, (hopefully) speeding up the computation. Since we are still dealing
with pure functions, however, we get none of the problems normally associated
with concurrent execution: no non-determinism, no need for locks, etc.
In this episode we will develop a pure but parallel implementation of linear
regression. We will briefly recap how linear regression works, before discussing
the two primitive functions that Haskell offers for pure parallelism: `par` and
`pseq`.
