That's close to "Hello World" in COBOL. Read a number and add it.
For anyone interested it sums all integers from 1 to 1000. Written as a benchmark for different languages.
Maybe the terminator was running a benchmark in those scenes :P
Not as far fetched. RDRAM does something similar when it comes online: it has to "train" the physical link every time the system is booted by generating bogus traffic and timing it (and can also retrain on certain errors). Complicated stuff, RDRAM. Also, anything with a differential pair may employ training like this.
As I type this, I am -literally- in the process of writing a self-timing loop using a binary increase of iterations to find average execution time plateau.
