Michael Wolf. A true poet who's code would shine even in a heap full of 
garbage.

Re: Prefetching and false sharing

['Nitsan Wakart' via mechanical-sympathy]

I'm a bit late to the party, yes JCTools pads 128, this was based on 
measurement and was visible on non-NUMA setups. See notes 
here:http://psy-lob-saw.blogspot.co.za/2013/10/spsc-revisited-part-iii-fastflow-sparse.html
Look for the comparison between Y8 and Y83 which compare 2 identical queues 
except for the padding size(64 vs 128). Tests were run on 
Ubuntu13.04/JDK7u40/i7-4700MQ@2.40GHz(so a 3 generations ago intel laptop 
Haswell CPU).
