Saving a Few Nanoseconds
by in Feature Articles on 2007-04-30Last month, in Saving a Few Minutes, we learned about G.R.G.'s experience with RUNPROG, one of the earliest examples of The Inner-Platform Effect I've ever seen. RUNPROG lived on an ancient supercomputer with an operating system that lacked the concept of search paths. Instead of a simple, four-line enhancement to "search another directory," RUNPROG was a 100,000-line assembly program that essentially did everything that the operating system did.
Although RUNPROG was entirely unnecessary, cost an incredible amount of time and money to maintain, and caused programs to run and load a magnitude slower, the business did not mind. It saved them money in the long run in that it allowed them to bill out even more CPU-time to their timesharing clients. In fact, after three short months of production use, the business had already forgotten the pain endured to create RUNPROG. That was, until Black Tuesday arrived.
