Given any task Π, Brandt’s speedup theorem (PODC 2019) provides a mechanical way to design another task Π' on the same input-set as Π such that, for any t ≥ 1, Π is solvable in t rounds in the LOCAL model if and only if Π' is solvable in t-1 rounds in the LOCAL model. We dissect the construction in Brandt’s speedup theorem for expressing it in the broader framework of all round-based models supporting full information protocols, which includes models as different as asynchronous wait-free shared-memory computing with iterated immediate snapshots, and synchronous failure-free network computing.
