Parallelising your code. Do you do it?   [Edit]

Survey period: 5 Jul 2010 to 12 Jul 2010

Our CPUs aren't getting as fast as fast as they used to, and we're now well and truly in a multi-core world. What do you do to take advantage of this? (Suggested by El Corazon)

I write image analysis software and parallel processing is an absolute must. BUT you better be careful - coding by the seat of your pants is asking for trouble. You have to spend some time designing how it's going to work, otherwise it probably won't, or (worse) it will work sometimes, or (even worse) it will work slightly differently each time. Yes, I have been reduced to swearing at my own software. Some careful planning and it shouldn't be too painful, just tedious. But you get to watch every core running flat out which is pretty funny. Hah! Who's making who work now?
