How many cores and SIMD lanes? What type of ANN did you use if for? Was it hard to implement into your existing code? This is a big deal for me, since I gave up

How many cores and SIMD lanes? What type of ANN did you use if for? Was it hard to implement into your existing code? This is a big deal for me, since I gave up C for Erlang/LFE, and I am working my way through Gene Sher's book 'Handbook of Neuroevolution Through Erlang'. I like the conceptual fit, but I would be more interested in the present to try this on some old C coded NNs.
