So, here is the problem I am having. I tried running the following timing program: https://github.com/ChisholmKyle/PosixMachTiming with the value in the loop increased to UINT_MAX to get better precision. (It also uses clock_gettime().) And then I run it twice but get different precisions. How does this happen? The number of operations are exactly the same (or should be).
