My code isn't very complete but since everyone else is sharing I'll post 
what I've got.

FWIW I had to go back pretty far and then still make changes to get a 
version of your soa_compare.benchmark.cpp that compiled on windows VS2015.

particle_count=1,000,000
minimum duration=2.85542

comparative performance table:

method   rel_duration
________ ______________
Aos      3.08266
SoA      1.51109
Flat     1.50358
StdArray 1.91317
Block    1.60447
SSE      1.35994
SSE_opt  1.18056
