Dear SpiNNaker and Spikey developers,

in case anyone is interested, my benchmarking results for running a
binary associative memory on NM-MC1 and Spikey in comparison to NEST
can be found in my master thesis available at

https://github.com/hbp-sanncs/master-thesis-astoeckel-2015/releases/do
wnload/v1.0/master_astoecke_design_space_exploration_2015.pdf

(I'll upload it on the official publishing platform of Bielefeld
University as soon as the holiday season is over.)

See Chapter 5 for the benchmarking experiments, which consist of two
dimensional neuron parameter sweeps and a one-dimensional system
(associative memory) parameter sweep. Both implicitly test the
quality of the neuron model implementation.

To summarise the relevant insights: the results for NM-MC1 are very
promising with only small deviations compared to the reference runs
on NEST. Perhaps unsurprisingly, Spikey deviates very strongly from
the reference behaviour, shows severe noise and more-or-less erratic
results in the system parameter sweeps.

It will be interesting to run larger scale experiments, as well as
experiments on NM-PM1 next year. All source code required for
repeating the experiments can be found at

Once again, thank your for your support and a happy new year,
Andreas Stöckel
