The parallelize Function

Run loop iterations across threads.

One Core Is Not Enough

A plain loop runs on a single core while the rest sit idle. For heavy work, that wastes most of your CPU.

for i in range(n):
    out[i] = heavy(i)

Parallelism means handing different loop iterations to different cores so they all work at the same time. 🧵
