 # Scheduling (OpenMP)
-**Scheduling** in OpenMP controls how loop iterations are divided among threads.
+**Scheduling** in OpenMP controls how loop iterations are divided among threads. By default, `parallel for` splits iterations into roughly equal static chunks assigned to threads upfront. This works well when each iteration takes the same time. When iteration cost varies, static assignment leaves some threads idle while others are still running. A loop where some values of `i` trigger much more work than others is a common example. The `schedule` clause selects the assignment strategy.
