Description
PlanZero models are computation recurrences. I'd like to maximize the opportunity for vectorized computation in evaluating each recurrence, by taking advantage of opportunities, wherever they arise, to compute several consecutive timesteps with vectorized computational expressions. I'm not aware of an open-source Python software project that implements such a scheduler.

Research direction
The issue names no files, tests, or entry points. Start by locating PlanZero’s recurrence-evaluation code, then review the related projects ModelX/LifeLib, Devito, and PyTensor’s Scan operator for scheduling approaches. Before implementation, define which consecutive timesteps can be vectorized and what behavior or performance improvement counts as done.
