Many biological phenomena, including peristalsis, circadian rhythms, and cardiac synchronization, may be modeled in terms of the collective behavior of non-linear oscillator ensembles. The possible types of synergetics include modelocking, amplitude death, quasiperiodicity, and chaos. This paper presents large-scale simulations on a SIMD-computer with a mesh architecture (the MasPar-1 or DECmpp 12000 system) of one- and two-dimensional arrays of disparate limit-cycle oscillators. The simulations have been optimized for this type of architecture and permit the determination of the collective behavior over time scales and for system sizes that are much larger than has hitherto been feasible.
