In the old days this was how parallel code was run and is still run on larger servers. If however, we have k < n computers we can run our models on, the total running time will n*s/k. If we have a single computer at our disposal and have to run n models, each taking s seconds, the total running time will be n*s. Parallel processing (in the extreme) means that all the f# processes start simultaneously and run to completion on their own. Once f1 completes, f2 begins, and the process repeats. Serial processing means that f1 runs first, and until f1 completes, nothing else can run. Let’s be a little more formal.Ĭonsider that we have a series of functions to run, f1, f2, etc. We’ve vaguely discussed this idea in passing, specifically in that *apply functions are faster than for loops (usually).
