Wrong variable in live poisson control code

Quick fix with https://github.com/SpiNNakerManchester/sPyNNaker/pull/733

Wrong variable in live poisson control code

I think however the correct fix is either of. 1. Check label first time it is used and go pop if wrong. 2. Check and fix the label every time...

allowing sub partitioning of keys for allowing retina/ssa to be filtered via routing

Too far behind and idea now done better elsewhere

Ring buffer sigma and spikes-per-second on a per synapse-type basis

Is this still valid?

No checking for round to zero or too big for int16 when scaling STDP parameters

Is this still an issue? if yes do you have a PR for your fix? if no pr do you have a sample script to replicate the error.

get_average_spike_rate could be more efficient

I would recommend counting per neuron. This is easier to implement and avoids the need to communicate between processors or even chips.

get_average_spike_rate could be more efficient

The classic way to do distributed average is using n_values and sum. The average is then the total(sum)/total(n_values) In our case we can compute n_values as we know how many...

get_average_spike_rate could be more efficient

On models that spike more than once per timestep n_values is still the number of timesteps! For example say something had the spikes 3, 0 1, 4, 2, 1, 3...

better delay_support_adder on second pass

yes doing it in the splitter and only adding to Machine graph is the nicest but probably hardest solution

better delay_support_adder on second pass

The biggest issue with move adding delays to the splitter is that then the DelayExtensionMachineVertex has no DelayExtensionVertex app vertex so the places where the Machine Vertex depends on the...
