Tickator is software model of parallel computation. Model, that is way different that multithreading, multiprocessing, functional programming, actors, fork-join, Disruptor, you-name-it.
On the opposite hand, model that is very similar to synchronous circuits that are known from electronics. It is much closer to hardware than traditional software so in future it will be easier to prepare specialized processors with thousands cores.
