From NAND to Tetris is probably the most popular

You can also try searching for classes entitled "Advanced Computer Architecture" like so:

I'd also check out Berkeley's FireSim tutorials and community

Best of luck! There is no down side to mastery of these dark arts ;)

Udacity courses on high performance computing are good MOOCs [1][2]. Also MIT's Computation Structures course [3] covers some quantitative performance modeling.

MIT has a course for the software side: https://ocw.mit.edu/courses/electrical-engineering-and-compu...

I would be interested to find out more about this too simply because MOOCs tend to attract people who are looking for hyped-up topics and taking shortcuts in a more general sense, while this topic is the opposite in many ways.

To open the question a little more, any resources, period?
