There is a size (around 1e5 connections) at which continuous networks (requiring to process every connection every time) become intolerably inefficient. 

Spiking networks (in which we keep a list of only those nodes which have had at least one 'spike' in their input, and don't touch any connections originating at other nodes) are necessary for efficient handling of large problems.

It is likely that this incremental interleaving of task with task-tracking will mean we lose most of the benefit of GPU or OMP implementations, so spiking will need to be saving at least 95% of the connection processing in order for the optimization to be worthwhile.  Therefore we will probably need two implementations of spiking!feedforward (one multiprocessing and one task-tracking) and analysis/tracking code to distinguish which which is likely to be faster.
