"Pragma Volatile(VARIABLE);" will mark a variable as 'undecidably mutable', something like a memory-mapped clock where any access of the value could have a different value -- I don't recall any way to bind a variable to a register, and in any case that's likely a bad idea: the compiler is typically smart enough to know when to put things in a register. -- Many men, working multiple years on the problem, are likely to have a better understanding of the how/when... this is precisely why the "big new overhaul" in programming is parallelism: the market selected C/C++ and thus bonded to a low-level view of computing (because it was "more efficient" and they had more "control") which is inherently a poor fit for the problem of parallelization.

You will get the same result every time you try to fit the code to the machine rather than the code to the problem. (Of course, sometimes the machine is the 'problem' as is the case with OSes and device rivers.)
