Amdahl's Law was taught in my Alma mater's "computer architecture" course. This course was primarily around CPU operation and law was specifically brought up in regards to instruction mixes and provided CPU execution units, but was then generalized.

This was the 2nd in a series of the four required courses "low level" courses (assembly programming, computer architecture, operating systems, compilers).

I am a systems software developer and Amdahl's Law is one of my standard interview questions.
