My take away from a quick read: If there are N items here that all need to be processed by procedure P, the naive solution is to loop N times spoon feeding the items into P. The preferred solution is to have P take a reference to entire sets of items, specifically arrays of items. This is nice! This to me seems very sensible whether you have some fancy hardware doing P in parallel, or even just a plain old FOR loop - in the latter case it's the same length loop as the naive solution but you don't expose your procedure call mechanism to the loop. And it's a win on the calling side bc it'll help declutter the business logic there.
