The parallel pointer machine is a synchronous collection of finite state transducers, each transducer receiving its inputs via pointers to the other transducers. Each transducer may change its input pointers dynamically by “pointer jumping”. These machines provide a simple example of a parallel model with a time-varying processor inter-connection structure, and are sufficiently powerful to simulate deterministic spaceS(n) within timeO(S(n)).
