Below are table of various projects that can completely exhaust n-bits of keyspace. In other words, counting completely and fully from 0 to 2ⁿ-1.
This Gist implies no discussion about how this is relevant to quantum computing using Grover's algorithm, meet-in-the-middle or birthday attacks, or anything of the like. It's strictly a Gist about raw speed, measuring the result in bits.
If you know of other noteworthy and verifiable brute force searching projects,

What is strict aliasing? First we will describe what is aliasing and then we can learn what being strict about it means.
In C and C++ aliasing has to do with what expression types we are allowed to access stored values through. In both C and C++ the standard specifies which expression types are allowed to alias which types. The compiler and optimizer are allowed to assume we follow the aliasing rules strictly, hence the term strict aliasing rule. If we attempt to access a value using a type not allowed it is classified as undefined behavior(UB). Once we have undefined behavior all bets are off, the results of our program are no longer reliable.
Unfortunately with strict aliasing violations, we will often obtain the results we expect, leaving the possibility the a future version of a compiler with a new optimization will break code we th
