[nengo-user] faq item: spaun memory requirements?

[Xuan Choo]

Hello Alan (and anyone else interested in running spaun),

Spaun is a rather hefty beast. It requires at least 24GB of ram to run the
model. The latency timings of the ram doesn't matter so much, it would just
affect the running speed of the model itself.
Spaun also requires about 2.5 hours of real world time to run 1 second of
simulated time. Note that this run time estimate is based on Spaun running
on a 8 core (16 hyperthreaded cores) 2.6GHz machine.

Cheers!
