Jeff Preshing gave a really good introduction to atomics at CppCon 2014.[1] He explains it so clearly that 1 day later I had a fully tested lock-free work stealing queue and a queue. One of my favorite talks of last year. [1]: [this video]

For those interested in the implementation of atomic operations see Jeff Preshing's "How Ubisoft Develops Games for Multicore - Before and After C++11", especially after 15m55s in on the video, or slide 37 of the pdf on github. Video: [this video] PDF: [LINK]

Similar talk: CppCon 2014: Jeff Preshing "How Ubisoft Develops Games for Multicore - Before and After C++11" [this video] Ubisoft's talk spends more time getting into the weeds with atomic ops. Naughty Dog's is more of an architecture discussion. If you can only watch one, I'll recommend Naughty Dog's.

I'm making a game/engine with efficiency/performance as a top goal. I'v spent years thinking about the design. And after i figured it out, i found a talk from an Ubisoft employee that is mostly what i came up with. The problems are many, especially since i want to support multiplayer. The biggest solutions are around how data is transformed and scheduling the code that transforms it, more or less. The talk: [this video]
